Description

Communication method and device
Technical Field
The present application relates to the field of communications technologies, and in particular, to a communication method and apparatus.
Background
With the development of the fifth generation mobile communication technology (5G), in the deployment of operators, a base station operating in an evolved universal mobile telecommunications system terrestrial radio access (E-UTRA) system and a base station operating in a 5G New Radio (NR) system may be configured to communicate with a terminal device together, that is, the terminal device may be connected to both the base station operating in the E-UTRA system (hereinafter, referred to as an E-UTRA base station) and the base station operating in an NR system (hereinafter, referred to as an NR base station), so that data may be transmitted using both the frequency of the E-UTRA system and the frequency of the NR system, thereby improving the throughput of the terminal device. Such a scenario, in which a terminal device is simultaneously connected to base stations of two different access technologies, may be referred to as multi-RAT dual connectivity (MR-DC).
In an MR-DC scenario, a master base station (MN) and a secondary base Station (SN) will cooperate together to communicate with a terminal device. The terminal device needs to report the capabilities of the MR-DC to the primary and secondary base stations, i.e. the E-UTRA and NR capabilities supported by the terminal device are visible to both the primary and secondary base stations. However, the main base station is responsible for coordinating the capabilities of the terminal device, such as band combining capability and baseband processing capability, between the main base station and the secondary base station. The primary base station provides the secondary base station with UE capabilities that can be used to configure a Secondary Cell Group (SCG). The secondary base station may request the UE capability for configuring the SCG from the master base station, but eventually the master base station determines whether to accept or reject the secondary base station SN capability request.
From the perspective of communication hardware, part of the communication hardware in the terminal equipment is required to communicate with the main base station, and the other part of the communication hardware is required to communicate with the auxiliary base station. The hardware capability of the communication of the terminal device includes, for example, radio frequency capability, which represents how many frequency resources the terminal device can use to communicate with the base station, and baseband processing capability, which represents the transmission rate when the terminal device communicates with the base station. Generally, the radio frequency capability and the baseband processing capability of the terminal device are determined, and the terminal device occupies more hardware capability when communicating with one base station, and then occupies less hardware capability when communicating with another base station, and vice versa. This requires that when a terminal device communicates with two base stations, the capabilities of each base station must be reasonably coordinated or partitioned so that both base stations can reasonably schedule data.
The foregoing introduces that in an MR-DC scenario, a terminal device may send capability information of the terminal device to a base station. However, in the MR-DC scenario, the terminal device only sends the capability information of the terminal device to the base station, and the base station does not know how to allocate the capability of the terminal device between the primary base station and the secondary base station, which may cause that neither the base station nor the terminal device can work normally.
Disclosure of Invention
The embodiment of the application provides a communication method and device, which are used for ensuring that a base station and terminal equipment can normally work in an MR-DC scene.
In a first aspect, a first communication method is provided, which may be performed by a communication apparatus, such as a terminal device or a chip provided in the terminal device. The method comprises the following steps: the terminal device determines a first matching relationship, wherein the first matching relationship comprises a matching relationship between at least one piece of first capability information and at least one piece of second capability information, the at least one piece of first capability information comprises capability information of the terminal device in a first communication system, and the at least one piece of second capability information comprises capability information of the terminal device in a second communication system; the terminal device sends the first matching relationship to at least one of a first network device and a second network device, wherein the terminal device is connected to the first network device and the second network device at the same time, the first network device operates under the first communication system, and the second network device operates under the second communication system.
In this embodiment, the terminal device may determine a first matching relationship, where the first matching relationship indicates a matching relationship between the first capability information and the second capability information of the terminal device, and then the network device may determine, according to the first matching relationship, a capability division condition of the terminal device, that is, may determine how to allocate the capability of the terminal device to the primary network device and the secondary network device. For example, the network device selects to allocate according to a first matching relationship, allocates first capability information indicated by the first matching relationship to the primary network device, allocates second capability information indicated by the first matching relationship to the secondary network device, and as long as the allocated capability information satisfies the first matching relationship, the terminal device can normally operate according to the capability thereof, and the network device can normally schedule the terminal device. Therefore, the method provided by the embodiment of the application can enable the network equipment and the terminal equipment to normally work in an MR-DC scene.
With reference to the first aspect, in a first possible implementation manner of the first aspect, the method further includes: the terminal device sends the at least one piece of first capability information to at least one of the first network device and the second network device; the terminal device sends the at least one piece of second capability information to at least one of the first network device and the second network device.
Since the terminal device sends the first matching relationship to the at least one network device, the terminal device may first send the at least one first capability information to the at least one network device, and the at least one network device may determine the capability partition of the terminal device according to the at least one first capability information and the first matching relationship. Similarly, if at least one network device needs to obtain at least one piece of second capability information, the terminal device may also send the at least one piece of second capability information to the at least one network device. If the terminal device needs to send at least one first capability information and at least one second capability information to the network device, the terminal device may send the at least one first capability information and the at least one second capability information to the at least one network device through one message to save signaling overhead, or the terminal device may send the at least one first capability information and the at least one second capability information to the at least one network device through different messages, respectively, so that confusion of the capability information may be avoided as much as possible through separate sending.
With reference to the first aspect or the first possible implementation manner of the first aspect, in a second possible implementation manner of the first aspect, the first capability information is first partial capability information of the terminal device in the first communication system, and the method further includes: and the terminal equipment sends at least one piece of third capability information to at least one of the first network equipment and the second network equipment, wherein the third capability information is second part capability information of the terminal equipment in the first communication system.
In the foregoing, it is introduced that the first capability information includes capability information of the terminal device in the first communication system, and the first capability information includes the first part of capability information of the terminal device in the first communication system, that is, the first capability information includes only a part of capability information of the terminal device in the first communication system, so that the terminal device may further send the second part of capability information of the terminal device in the first communication system to at least one network device in order to enable the network device to obtain more capability information of the terminal device in the first communication system. As an example, the sum of the first part of capability information and the second part of capability information of the terminal device in the first communication system is the total capability information of the terminal device in the first communication system, so that the network device can obtain the total capability information of the terminal device, and thus the terminal device can be better scheduled.
With reference to the second possible implementation manner of the first aspect, in a third possible implementation manner of the first aspect, the method further includes: the terminal device sends at least one third capability information identifier to at least one of the first network device and the second network device, where one third capability information identifier indicates one third capability information.
That is, the identifier of the third capability information, sent by the terminal device to the at least one network device, and after receiving the identifier of the third capability information, the network device can also determine the third capability information of the terminal device. The third capability information identifier generally has a smaller information amount than the third capability information, so that the transmission overhead can be effectively saved.
With reference to the first aspect or any one possible implementation manner of the first aspect to the third possible implementation manner of the first aspect, in a fourth possible implementation manner of the first aspect, the second capability information is first partial capability information of the terminal device in the second communication system, and the method further includes: and the terminal equipment sends at least one piece of fourth capability information to at least one of the first network equipment and the second network equipment, wherein the fourth capability information is second part capability information of the terminal equipment in the second communication system.
Similar to the first capability information, the second capability information may include the first part of capability information of the terminal device in the second communication system, that is, the second capability information includes only a part of capability information of the terminal device in the second communication system, and then, in order to enable the network device to obtain more capability information of the terminal device in the second communication system, the terminal device may further send the second part of capability information of the terminal device in the second communication system to at least one network device. As an example, the sum of the first part of capability information and the second part of capability information of the terminal device in the second communication system is all capability information of the terminal device in the second communication system, so that the network device can obtain all capability information of the terminal device, and thus the terminal device can be better scheduled.
With reference to the fourth possible implementation manner of the first aspect, in a fifth possible implementation manner of the first aspect, the method further includes: the terminal device sends at least one fourth capability information identifier to at least one of the first network device and the second network device, where one fourth capability information identifier indicates one fourth capability information.
Similarly to the third capability information identifier, the terminal device may also be an identifier of the fourth capability information, which is sent to the at least one network device by the terminal device, and after receiving the fourth capability information identifier, the network device may also determine the fourth capability information of the terminal device. The fourth capability information identifier generally has a smaller information amount than the fourth capability information, so that the transmission overhead can be effectively saved.
With reference to the first aspect or any possible implementation manner of the first aspect to the fifth possible implementation manner of the first aspect, in a sixth possible implementation manner of the first aspect, the matching relationship between the at least one piece of first capability information and the at least one piece of second capability information specifically includes: the first matching relationship comprises at least one piece of first information, and one piece of the first information indicates the matching relationship between one piece of first capability information and one piece of second capability information; the first information is a first value indicating that the matching relationship between the one first capability information and the one second capability information is not supported; the first information is at least one second matching relationship indicating a matching relationship supporting the one first capability information and the one second capability information, wherein one second matching relationship is a matching relationship between third capability information and fourth capability information, or one second matching relationship is a matching relationship between a third capability information identifier and a fourth capability information identifier.
If each of the at least one first capability information included in the first matching relationship represents a first part of capability information of the terminal device under the first communication system, each of the at least one second capability information included in the first matching relationship represents a first part of capability information of the terminal device under the second communication system, the first matching relationship is equivalent to only indicating a matching relationship between the first part of capability information of the terminal device under the first communication system and the first part of capability information of the terminal device under the second communication system, and the terminal device has other capability information under the first communication system, for example, third capability information, and similarly, the terminal device also has other capability information under the second communication system, for example, fourth capability information, and a certain matching relationship is required between the third capability information and the fourth capability information, if the terminal device does not inform the network device about these matching relationships, the network device may likewise not know how the capabilities of the terminal device are divided.
In view of this, in the embodiment of the present application, a first value may be set for the first information, and if the value of the first information is the first value, the first information indicates that the corresponding matching relationship is not supported, that is, the matching relationship between a first capability information and a second capability information corresponding to the first information is not supported, in addition, the first information may also include at least one second matching relationship in addition to the first value, which indicates that the corresponding matching relationship is supported, that is, the matching relationship between a first capability information and a second capability information corresponding to the first information is supported, and a second matching relationship indicates the matching relationship between a third capability information and a fourth capability information. Therefore, the matching relationship between the first capability information and the second capability information and the matching relationship between the third capability information and the fourth capability information can be sent to the network equipment together through the first matching relationship without sending additional matching relationships, which is beneficial to reducing the interaction process between the equipment and reducing the transmission overhead. And direct indication is carried out through the first matching relationship, and the mode is simpler.
With reference to the first aspect or any possible implementation manner of the first aspect to the fifth possible implementation manner of the first aspect, in a seventh possible implementation manner of the first aspect, the determining that the first matching relationship includes a matching relationship between at least one piece of first capability information and at least one piece of second capability information specifically includes: the first matching relationship comprises at least one piece of first information, and one piece of the first information indicates the matching relationship between one piece of first capability information and one piece of second capability information; the first information is a first value indicating that the matching relationship between the one first capability information and the one second capability information is not supported; the first information is a second value indicating that a matching relationship between the one first capability information and the one second capability information is supported.
As a simpler example, for example, a first message may be implemented by 1 bit, if the value of the 1 bit is 1, it indicates that the corresponding matching relationship is supported, and if the value of the 1 bit is 0, it indicates that the corresponding matching relationship is not supported. In this way, on the premise of ensuring that the first matching information can effectively indicate the matching relationship between the first capability information and the second capability information, the amount of information included in the first matching relationship is reduced as much as possible, thereby reducing the transmission overhead.
With reference to the seventh possible implementation manner of the first aspect, in an eighth possible implementation manner of the first aspect, the method further includes: the terminal device sends at least one third matching relationship to at least one of the first network device and the second network device, where each third matching relationship corresponds to a matching relationship between one of the first capability information and one of the second capability information, the first information corresponding to the matching relationship between one of the first capability information and one of the second capability information is the second value, one third matching relationship includes at least one second matching relationship, and one second matching relationship is a matching relationship between third capability information and fourth capability information, or one second matching relationship is a matching relationship between a third capability information identifier and a fourth capability information identifier.
It was introduced above that if each of the at least one first capability information included in the first matching relationship represents a first part of capability information of the terminal device under the first communication system, each of the at least one second capability information included in the first matching relationship represents a first part of capability information of the terminal device under the second communication system, then the first matching relationship is only equivalent to indicating a matching relationship between the first part of capability information of the terminal device under the first communication system and the first part of capability information of the terminal device under the second communication system, and the terminal device has other capability information under the first communication system, for example, also the third capability information, and similarly, the terminal device also has other capability information under the second communication system, for example, also the fourth capability information, the third capability information and the fourth capability information also need a certain matching relationship, and the terminal device also needs to send to the network device. Then, the terminal device may send at least one third matching relationship to the network device separately, where each third matching relationship corresponds to a matching relationship between one piece of the first capability information and one piece of the second capability information, and one third matching relationship includes at least one second matching relationship, and the second matching relationship is a matching relationship between the third capability information and the fourth capability information. That is, the terminal device may send the first matching relationship and the at least one third matching relationship to the network device, respectively, so that the network device can determine all capability partitioning conditions of the terminal device. And different matching relations are sent separately, so that confusion of the matching relations can be avoided.
With reference to the first aspect or any one possible implementation manner of the first aspect to the eighth possible implementation manner of the first aspect, in a ninth possible implementation manner of the first aspect, before the sending, by the terminal device, the first matching relationship to at least one of the first network device and the second network device, the method further includes: the terminal device receives a capability request message from at least one of the first network device and the second network device, where the capability request message is used to request the terminal device to send capability information of the terminal device.
That is to say, the network device may send the capability request message to the terminal device when the network device needs to obtain the capability information of the terminal device, and the terminal device may send the first matching relationship to the network device after receiving the capability request message from the network device, so that the sending of the first matching relationship better meets the requirement of the network device. Of course, the terminal device may also actively send the first matching relationship to the network device, without a request from the network device, so that an interaction process of signaling may be reduced.

Then, after the decision, the main network device may send a notification message to another network device in addition to determining how the terminal device should be scheduled, and then the other network device may determine how to schedule the terminal device after receiving the notification message.
With reference to the second aspect or any possible implementation manner of the first possible implementation manner of the second aspect to the ninth possible implementation manner of the second aspect, in a tenth possible implementation manner of the second aspect, before the network device receives the first matching relationship from the terminal device or another network device, the method further includes: and the network equipment sends a capacity request message to the terminal equipment, wherein the capacity request message is used for requesting the terminal equipment to send the capacity information of the terminal equipment.

The terminal device can divide the capability information of the terminal device into at least two parts, and the capability information can be sent separately when being sent to the network device, so that the information amount included in one message can be reduced, and the condition of network congestion can be avoided as much as possible. In addition, taking the example of dividing the parameter set according to the value conditions of the parameters and dividing the parameter set into the first part of parameters and the second part of parameters, it can be seen that the first part of parameters is fixed parameters, that is, the first capability information corresponds to fixed capability, and for a band combination, only one value set of the first part of parameters corresponds, for example, for the first communication system, only one first capability information corresponds, so that for the parameters with unchanged values in the parameter set, the values of the parameters are sent to the network device only once without being sent for multiple times, thereby reducing the amount of repeatedly sent information and saving the overhead.

S11: when the network device sends a UE capability request message to the terminal device, the terminal device receives the UE capability request message from the network device, where the UE capability request message is used to request the terminal device to send a radio access capability of the terminal device in a Radio Access Technology (RAT). The UE capability request message may include one or more RATs (e.g., one or more of evolved universal mobile telecommunications system terrestrial radio access (E-UTRA) technology, universal mobile telecommunications system terrestrial radio access (UTRA) technology, new radio (or new air interface) technology (NR), and E-UTRA-NR) indication requesting capability information of the terminal device under the RAT.
It should be noted that, for a terminal device in a connected state, when the network device needs further capability information of the terminal device, the network device may initiate a UE capability request procedure to request the required capability information.
S12: and the terminal equipment sends the UE capability message to the network equipment, and the network equipment receives the UE capability message from the terminal equipment. The UE capability message carries capability information of the terminal device, where the capability information of the terminal device is a wireless access capability of the terminal device in a certain wireless access technology. If a certain RAT is included in the UE capability request message, the terminal device needs to include capability information of the certain RAT in the UE capability message and set the RAT type parameter in the UE capability message to the certain RAT. For example: UE capability information of E-UTRA-NR is requested in the UE capability request message, the terminal equipment needs to include the capability information of E-UTRA-NR in the UE capability message, and the RAT type parameter in the UE capability message is set to eutra-NR.
It can be seen that, currently, the terminal device sends the capability information of the terminal device to the network device, so that the network device schedules the terminal device according to the capability of the terminal device. In addition, the terminal device may correspond to different capabilities in different communication systems, for example, if the terminal device accesses a network device in an LTE system, the terminal device may send capability information of the terminal device in an E-UTRA system to the network device in the LTE system, or if the terminal device accesses a network device in an NR system, the terminal device may send capability information of the terminal device in the NR system to the network device in the NR system, and the whole process may refer to the process shown in fig. 1.
The capability of the terminal device may be different according to the frequency band (band) in which the terminal device operates, and the supported frequency bands may be different when the terminal device is in different communication systems. For convenience of description herein, the concept of band combination is directly applied, and a band combination includes at least one band that includes a bandwidth from one frequency point to another, for example, E-UTRA uplink band 9 represents 880 MHz-915 MHz, and E-UTRA downlink band 9 represents 925 MHz-960 MHz. Of course, in a communication system, there may be overlapping portions of the frequency bands included in different combinations of frequency bands supported by the terminal device. Under the NR system, for example, it is considered that a terminal device may support one or more band combinations, each of which includes at least one band. For example, in the NR system, a terminal device supports a frequency band a and a frequency band B, where the frequency band a and the frequency band B can be simultaneously supported, the terminal device can be considered to support 3 frequency band combinations, a first frequency band combination of the 3 frequency band combinations includes a frequency band a, a second frequency band combination includes a frequency band B, and a third frequency band combination includes frequency bands a and B, and each frequency band combination can correspond to different capabilities, for example, a capability corresponding to the first frequency band combination includes a capability 1, a capability corresponding to the second frequency band combination includes a capability 2 and a capability 3, and a capability corresponding to the third frequency band combination includes a capability 1, a capability 2 and a capability 3. The same is true for the E-UTRA system. The capability information sent by the terminal device to the network device includes the capability information of the terminal device at each frequency band combination supported by the terminal device, that is, includes information of each capability of the terminal device at each frequency band combination supported by the terminal device.
With the development of 5G technology, in the deployment of operators, a network device operating in an E-UTRA system and a network device operating in an NR system may be configured to communicate with a terminal device together, that is, the terminal device may be connected to both a network device operating in an E-UTRA system (hereinafter, referred to as an E-UTRA network device) and a network device operating in an NR system (hereinafter, referred to as an NR network device), so that data may be transmitted by using both the frequency of the E-UTRA system and the frequency of the NR system, thereby improving the throughput of the terminal device, and this scenario may be referred to as an MR-DC scenario.
In the MR-DC scenario, the primary network device and the secondary network device will cooperate together in communication with the terminal device. This requires, from the hardware perspective of communication, that one part of the hardware of the terminal device that communicates communicate with the primary network device and another part with the secondary network device. Generally, the hardware capability of the terminal device is determined, or the capability of the terminal device is determined, and if the terminal device occupies more hardware resources when communicating with one network device, the terminal device occupies less hardware resources when communicating with another network device.
As can be seen from the foregoing description, in the case that the terminal device is connected to only one network device, the terminal device may send the capability information of the terminal device to the network device, and then it may be determined that, in the MR-DC scenario, the terminal device may also send the capability information of the terminal device to the network device. However, in the MR-DC scenario, the terminal device only sends the capability information of the terminal device to the network device, and the network device side does not know how to allocate the capability of the terminal device between the primary network device and the secondary network device. Taking as an example that the terminal device is connected to a network device under an NR system and a network device under an E-UTRA system in an MR-DC scenario, the terminal device supports for example 3 band combinations under the NR system, each band combination may correspond to at least one capability, e.g., 5 capabilities for the 3 band combinations, e.g., 2 band combinations are supported in the E-UTRA system, each of the frequency band combinations may correspond to at least one capability, for example, the 2 frequency band combinations correspond to 2 capabilities, so that only one capability is applied to two network devices connected to the terminal device, for example, a network device in the NR system may utilize one capability of a certain band combination of the terminal device in the NR system, and a network device in the E-UTRA system may utilize one capability of a certain band combination of the terminal device in the E-UTRA system. However, the problem is that not every capability under the E-UTRA system and any capability under the NR system can be matched, where the matching is that the terminal device can simultaneously support, for example, capability 1 of band combination 1 of the terminal device under the E-UTRA system may only be matched with capability 2 of band combination 2 of the terminal device under the NR system, the terminal device can simultaneously support capability 1 of band combination 1 under the LTE system and capability 2 of band combination 2 under the NR system, but capability 1 of band combination 1 of the terminal device under the LTE system cannot be matched with capability 3 of band combination 2 of the terminal device under the NR system, that is, the terminal device cannot simultaneously support capability 1 of band combination 1 under the E-UTRA system and capability 3 of band combination 2 under the NR system.
Then, the terminal device only sends the capability information of the terminal device under two communication systems to the network device in a unified manner, and with reference to the example in the previous paragraph, the terminal device supports, for example, 3 frequency band combinations under the NR system, where the 3 frequency band combinations correspond to 5 capabilities, and supports, for example, 2 frequency band combinations under the E-UTRA system, where the 2 frequency band combinations correspond to 2 capabilities, then the terminal device may only send the information of the 7 capabilities to the network device in a unified manner, and the network device does not know how to select after receiving the capability information, which may cause the network device and the terminal device to fail to operate normally.
Or, the embodiment of the present application provides an assumption that, for example, in an EN-DC scenario, a terminal device needs to report a frequency band combination manner of all supported E-UTRA and NR in the EN-DC scenario, and because there are multiple possible frequency band combinations between each frequency band combination of E-UTRA and each frequency band combination of NR, the possibility of frequency band combinations of all supported E-UTRA and NR in the EN-DC scenario is very high, and the terminal device reports the combinations to a network device one by one, so that when the terminal device reports capability information of the terminal device, the amount of content that needs to be reported is too large. Moreover, among a plurality of possible combinations of E-UTRA and NR frequency band combinations, some E-UTRA frequency band combinations or some NR frequency band combinations may report repeatedly, for example, one E-UTRA frequency band combination may be combined with either NR frequency band combination 1 or NR frequency band combination 2, so that the terminal device reports the two combinations, which causes repeated reporting of E-UTRA frequency band combination information, which further causes a problem of too large content when the terminal device reports the capability information of the terminal device, thereby causing unnecessary overhead.
In view of this, the embodiments of the present application provide a communication method to ensure that the network device and the terminal device achieve normal operation in the MR-DC scenario as much as possible, and the embodiments of the present application also aim to consider reducing overhead.
The technical solution provided by the embodiment of the present application may be applied to an MR-DC scenario, or may also be applied to other scenarios, for example, as long as the terminal device is connected to at least two network devices, the technical solution provided by the embodiment of the present application may be applied no matter what communication system the at least two network devices operate in.
Please refer to fig. 2, which is an application scenario of the embodiment of the present application. In fig. 2, two network devices and a terminal device are included, where the two network devices are a first network device and a second network device respectively, the first network device may be a main network device of the terminal device, and the second network device is a secondary network device of the terminal device, or the first network device is a secondary network device of the terminal device, and the second network device is a main network device of the terminal device, and both of the two network devices are base stations, for example, then the main network device is a main base station, and the secondary network device is a secondary base station. The first network device operates in an E-UTRA system, for example, and the second network device operates in an NR system, for example, i.e., the first network device operates in an E-UTRA system, for example, and the second network device operates in an NR system, for example, or the first network device operates in an NR system, for example, and the second network device operates in an E-UTRA system, for example, i.e., the first network device operates in an NR network, for example, and the second network device operates in an E-UTRA system, for example, and the second network device operates in an E-UTRA network device, for example. Wherein the terminal device is connected to both network devices simultaneously, and the terminal device can communicate with both network devices.
The technical scheme provided by the embodiment of the invention is described below by combining the accompanying drawings.
In the embodiment of the present application, the first communication system may refer to an E-UTRA system and the second communication system may refer to an NR system, or the first communication system may refer to an NR system and the second communication system may refer to an E-UTRA system, and in the following description, two communication systems, i.e., the E-UTRA system and the NR system, are mainly taken as an example. Alternatively, the first communication system and/or the second communication system may also be future upcoming communication systems, without limitation.
An embodiment of the present application provides a communication method, please refer to fig. 3, which is a flowchart of the method. In the following description, the method provided by the embodiment of the present application is applied to the application scenario shown in fig. 2 as an example.
S31, the terminal device determines a first matching relationship, wherein the first matching relationship comprises a matching relationship between at least one piece of first capability information and at least one piece of second capability information, the at least one piece of first capability information comprises capability information of the terminal device in a first communication system, and the at least one piece of second capability information comprises capability information of the terminal device in a second communication system;
s32, if the terminal device sends the first matching relationship to at least one of a first network device and a second network device, the at least one of the first network device and the second network device receives the first matching relationship from the terminal device, where the terminal device is connected to the first network device and the second network device at the same time, the first network device operates under the first communication system, and the second network device operates under the second communication system; in addition, fig. 3 is an example in which the terminal device sends the first matching relationship to both the first network device and the second network device;
s32, the first network device and the second network device determine the capability division of the terminal device according to the first matching relation.
In this embodiment, the terminal device may actively send the capability partition condition of the terminal device to the network device, that is, actively send the first matching relationship information, or at least one of the first network device and the second network device may send a capability request message to the terminal device, where the capability request message is used to request the terminal device to send the capability information of the terminal device, and then the terminal device may send the first matching relationship to the network device.
The capability of the terminal device may be understood as the capability of the terminal device under the corresponding frequency band combination. The capability of the terminal device under a frequency band combination is embodied by a plurality of parameters corresponding to the frequency band combination, such as the parameters included in the capability information. The parameter for indicating the capability of a frequency band combination may be understood to be included in a parameter set, that is, the capability of a frequency band combination may be embodied by a parameter included in the parameter set, and the parameter set includes at least one parameter. Of course, the concept of parameter sets is presented here only for easy understanding, and the parameter set combination does not necessarily exist, that is, the parameters for representing the capability of one frequency band combination are not necessarily set in one parameter set.
As can be seen from the foregoing description, a piece of first capability information includes capability information of the terminal device under the first communication system, and specifically, a piece of first capability information includes all capability information of the terminal device under the first communication system, or a first part of capability information, that is, a part of capability information of the terminal device under the first communication system. It is also introduced above that a first capability information may be specifically understood to include the capability of a frequency band combination of the terminal device under the first communication system, and accordingly, a first capability information may include all the capability information of a frequency band combination of the terminal device under the first communication system, or a first part of capability information, that is, a part of capability information, of a frequency band combination of the terminal device under the first communication system. That is, the total capability information or the first partial capability information included in one piece of first capability information is conditional in nature, and does not mean the total capability information or the first partial capability information of the terminal device in any case in the first communication system, but means the total capability information or the first partial capability information of one band combination of the terminal device in the first communication system, and the band combination is the band combination of the first communication system corresponding to the matching relationship corresponding to the first capability information. The meaning of a second capability information is also understood and not described in detail.
As an embodiment, the first capability information includes all capability information of the terminal device in the first communication system, and it may be understood that one first capability information is a value of a parameter set corresponding to one frequency band combination supported by the terminal device in the first communication system. For example, a frequency band combination supported by the terminal device in the first communication system corresponds to a parameter set, and different first capability information may be obtained when values of parameters included in the parameter set are different, or it may be understood that a first capability information indicates a capability corresponding to a frequency band combination supported by the terminal device in the first communication system. For example, the first communication system is an NR system, one frequency band combination supported by the terminal device under the NR system is a frequency band combination 1, which corresponds to one parameter set, where the parameter set includes a parameter a, a parameter B, and a parameter C, when a value of the parameter a is a1, a value of the parameter B is B1, and a value of the parameter C is C1, a1, B1, and C1 constitute one first capability information of the frequency band combination 1, when a value of the parameter a is a2, a value of the parameter B is B1, and a value of the parameter C is C1, a2, B1, and C1 constitute another first capability information of the frequency band combination 1, and so on, each first capability information of the frequency band combination 1 includes all capability information of the frequency band combination 1. Of course, how each parameter can take value is determined by the terminal device according to the capability of the terminal device.
As another embodiment, the one first capability information includes a first part of capability information of the terminal device under the first communication system. The parameters included in the parameter set corresponding to one frequency band combination supported by the terminal device in the first communication system may be divided into at least two parts, where each part may include at least one parameter. One of the portions is referred to as a first partial parameter, and the first partial parameter represents first capability information, which can be understood as a first capability information that is a value of the first partial parameter in a parameter set corresponding to a frequency band combination. For example, a frequency band combination supported by the terminal device in the first communication system corresponds to a parameter set, and the parameter set is divided into at least two parts, wherein at least one parameter belongs to the first part of parameters obtained by the division, and then different first capability information can be obtained when the values of the parameters included in the first part of parameters are different. For example, the first communication system is an NR system, a frequency band combination supported by the terminal device under the NR system is a frequency band combination 1, which corresponds to a parameter set, the parameter set includes a parameter a, a parameter B and a parameter C, the parameter set is divided into at least two parts, for example, into two parts, where the parameter a and the parameter C belong to a first part of parameters, and the parameter B belongs to a second part of parameters, then, when the parameter a takes a value of a1 and the parameter C takes a value of C1, a1 and C1 constitute a first capability information of the frequency band combination 1, when the parameter a takes a value of a2 and the parameter C takes a value of C1, a2 and C1 constitute another first capability information of the frequency band combination 1, and so on, the same for the second part of parameters, different values of the parameter B may constitute different capability information, and capability information represented by the second part of parameters is referred to as third capability information, that is, different values of the parameter B may constitute different third capability information. Each piece of first capability information of the band combination 1 includes a first part of capability information of the band combination 1, that is, capability information embodied by a first part of parameters. Each third capability information of the band combination 1 includes the second partial capability information of the band combination 1, i.e. the capability information embodied by the second partial parameter. Of course, how each parameter in the at least two parts in one parameter set can take value is determined by the terminal device according to the capability of the terminal device.
The above-described division of a parameter set into at least two parts, where the specific number of the at least two parts may be set by a protocol or may be predefined by a network device or a terminal device. The dividing modes may be multiple, for example, the dividing modes may be divided randomly, or the dividing modes may be divided according to the importance of the parameter, for example, the more important parameter is divided into one part, or the dividing modes may be divided according to whether the value of the parameter changes, and the following description focuses on the dividing modes according to whether the value of the parameter changes.
For example, values of some parameters are not changed, that is, values of some parameters in a parameter set corresponding to a band combination may be fixed, and values of some parameters may be changed, for example, a carrier aggregation band level (ca-bandwidth class), which may be different levels such as a, b, and c … …. Then, according to the parameter value, the parameters included in the parameter set may be divided into a first part of parameters and a second part of parameters, where the first part of parameters includes parameters whose values do not change, and thus the first part of parameters may also be referred to as fixed parameters, the capability represented by the first part of parameters may also be referred to as fixed capability, and the second part of parameters includes parameters whose values change, and thus the second part of parameters may also be referred to as variable parameters, and the capability represented by the second part of parameters may also be referred to as variable capability. The parameters are divided according to the value conditions of the parameters, so that the management of the parameters is more effective.
For example, the first communication system is an NR system, and a frequency band combination supported by the terminal device under the NR system is a frequency band combination 1, which corresponds to a parameter set, where the parameter set includes a parameter a, a parameter B, and a parameter C, and the parameter set is divided into at least two parts according to whether values of the parameters are variable, where the parameter a and the parameter C are parameters whose values do not change, and are divided into first part parameters, and the parameter B is a parameter whose value changes, and is divided into second part parameters. The values of the parameter a and the parameter C are not changed, for example, the value of the parameter a is a1, and the value of the parameter C is C1, then a1 and C1 constitute the first capability information of the band combination 1, and the band combination 1 corresponds to only the first capability information. However, the value of the parameter B may vary, and each possible value of the parameter B may constitute a third capability information, that is, a third capability information is a value of a second part of parameters in a parameter set corresponding to a frequency band combination, and for the frequency band combination 1, one or more third capability information may be corresponding.
As in the above two embodiments, it can be simply understood that the first capability information includes all capability information or part of capability information of the terminal device in one frequency band combination of the first communication system. The same applies to the second capability information, which is briefly described below.
As an embodiment, the second capability information includes all capability information of the terminal device in the second communication system, and it can be understood that one second capability information is a value of a parameter set corresponding to one frequency band combination supported by the terminal device in the second communication system. For example, a frequency band combination supported by the terminal device in the second communication system corresponds to a parameter set, and different second capability information may be obtained when values of parameters included in the parameter set are different, or it may be understood that a second capability information indicates a capability corresponding to a frequency band combination supported by the terminal device in the second communication system. For example, a frequency band combination supported by the terminal device in the second communication system corresponds to a parameter set, and different second capability information may be obtained when values of parameters included in the parameter set are different. For example, the second communication system is an E-UTRA system, one frequency band combination supported by the terminal device in the E-UTRA system is a frequency band combination 2, which corresponds to one parameter set, where the parameter set includes a parameter D, a parameter E, and a parameter F, when a value of the parameter D is D1, a value of the parameter E is E1, and a value of the parameter F is F1, D1, E1, and F1 constitute one second capability information of the frequency band combination 2, when a value of the parameter D is D2, a value of the parameter E is E1, and a value of the parameter F is F1, D2, E1, and F1 constitute another second capability information of the frequency band combination 2, and so on, each second capability information of the frequency band combination 2 includes all capability information of the frequency band combination 2. Of course, how each parameter can take value is determined by the terminal device according to the capability of the terminal device.
As another embodiment, the one second capability information includes a first part of capability information of the terminal device under the second communication system. The parameters included in the parameter set corresponding to one frequency band combination supported by the terminal device in the second communication system may be divided into at least two parts, where each part may include at least one parameter. One of the portions is referred to as a first partial parameter, and the first partial parameter represents second capability information, so that it can be understood that one second capability information is a value of the first partial parameter in a parameter set corresponding to one frequency band combination. For example, a frequency band combination supported by the terminal device in the second communication system corresponds to a parameter set, and the parameter set is divided into at least two parts, wherein at least one parameter belongs to the first part of parameters obtained by division, and then different second capability information can be obtained when the values of the parameters included in the first part of parameters are different. For example, the second communication system is an E-UTRA system, a frequency band combination supported by the terminal device in the E-UTRA system is a frequency band combination 2, which corresponds to a parameter set, the parameter set includes a parameter D, a parameter E and a parameter F, the parameter set is divided into at least two parts, for example, the two parts are divided, where the parameter D and the parameter F belong to a first part of parameters, and the parameter E belongs to a second part of parameters, then, when the parameter D takes the value D1 and the parameter F takes the value F1, D1 and F1 constitute a second capability information of the frequency band combination 2, when the parameter D takes the value D2 and the parameter F takes the value F1, D2 and F1 constitute another second capability information of the frequency band combination 2, and so on, for the second part of parameters also, the same, different values of the parameter E may constitute different capability information, the capability information represented by the second part of parameters is referred to as fourth capability information, that is, different values of the parameter E may constitute different fourth capability information. Each second capability information of the band combination 2 includes a first part of capability information of the band combination 2, i.e. capability information embodied by a first part of parameters. Each fourth capability information of the band combination 2 includes the second partial capability information of the band combination 2, i.e. the capability information embodied by the second partial parameter. Of course, how each parameter in the at least two parts in one parameter set can take value is determined by the terminal device according to the capability of the terminal device.
The above-described division of a parameter set into at least two parts, where the specific number of the at least two parts may be set by a protocol or may be predefined by a network device or a terminal device. And the division mode may be various, for example, the division may be random, or the division may be performed according to the value of the parameter. For example, the values of some parameters are not changed, that is, the values of some parameters may be fixed, and the values of some parameters may be changed in the parameters corresponding to one frequency band combination. Then, according to the parameter value, the parameters included in the parameter set may be divided into a first part of parameters and a second part of parameters, where the first part of parameters includes parameters whose values do not change, and thus the first part of parameters may also be referred to as fixed parameters, the capability represented by the first part of parameters may also be referred to as fixed capability, and the second part of parameters includes parameters whose values change, and thus the second part of parameters may also be referred to as variable parameters, and the capability represented by the second part of parameters may also be referred to as variable capability.
For example, the second communication system is an E-UTRA system, and a frequency band combination supported by the terminal device in the E-UTRA system is a frequency band combination 2, which corresponds to a parameter set, the parameter set includes a parameter D, a parameter E, and a parameter F, and the parameter set is divided into at least two parts according to whether the value of the parameter is variable, where the parameter D and the parameter F are parameters whose values are not variable, and are divided into first part parameters, and the parameter E is a parameter whose value is variable, and is divided into second part parameters. The values of the parameter D and the parameter F are not changed, for example, the value of the parameter D is D1, and the value of the parameter F is F1, then D1 and F1 constitute the second capability information of the band combination 2, and the band combination 2 only corresponds to the second capability information. The value of the parameter E may vary, and each possible value of the parameter E may constitute fourth capability information, that is, a fourth capability information is a value of a second part of parameters in a parameter set corresponding to a frequency band combination, and for the frequency band combination 2, one or more fourth capability information may be corresponding.
As described above, the first capability information includes all capability information or partial capability information of the terminal device in one frequency band combination of the first communication system, and the second capability information includes all capability information or partial capability information of the terminal device in one frequency band combination of the second communication system, so that the first capability information and the second capability information may be combined differently for the first matching relationship. For example, each of the at least one first capability information included in the first matching relationship may represent all capability information of the terminal device under the first communication system, and each of the at least one second capability information included in the first matching relationship may represent all capability information of the terminal device under the second communication system; or, each piece of first capability information in the at least one piece of first capability information included in the first matching relationship may represent a first part of capability information of the terminal device in the first communication system, and each piece of second capability information in the at least one piece of second capability information included in the first matching relationship may represent a first part of capability information of the terminal device in the second communication system; or, each of the at least one first capability information included in the first matching relationship may represent all capability information of the terminal device in the first communication system, and each of the at least one second capability information included in the first matching relationship may represent a first part of capability information of the terminal device in the second communication system; or, each of the at least one first capability information included in the first matching relationship may represent a first part of capability information of the terminal device in the first communication system, and each of the at least one second capability information included in the first matching relationship may represent all capability information of the terminal device in the second communication system.
As can be seen from the foregoing description, the terminal device may support at least one frequency band combination in the first communication system, each frequency band combination may correspond to one first capability information or a plurality of first capability information, and similarly, the terminal device may also support at least one frequency band combination in the second communication system, each frequency band combination may correspond to one second capability information or a plurality of second capability information, and only one first capability information is selected for the first network device and only one second capability information is selected for the second network device. Since the terminal device is connected to the first network device and the second network device at the same time, the terminal device needs to support the first capability information applied by the first network device and the second capability information applied by the second network device at the same time. However, the frequency band combination supported by the terminal device in the first communication system corresponds to at least one first capability information, the frequency band combination supported by the terminal device in the second communication system corresponds to at least one second capability information, but not any combination of the first capability information and any second capability information, and the terminal device can support the first capability information and the second capability information simultaneously, for example, the first capability information corresponding to the frequency band combination supported by the terminal device in the first communication system includes a first capability information a and a first capability information B, the second capability information corresponding to the frequency band combination supported by the terminal device in the second communication system includes a second capability information C and a second capability information D, wherein the first capability information a and the second capability information C cannot be supported simultaneously by the terminal device, that is, if the first network device selects the first capability information a, if the second network device selects the second capability information C, the terminal device cannot support the second capability information C, and thus the network device cannot normally schedule the terminal device.
In view of this, in this embodiment, the terminal device may determine a first matching relationship, where the first matching relationship includes a matching relationship between at least one first capability information and at least one second capability information, and it may be understood that the first matching relationship includes multiple matching relationships (or specifically, the first matching relationship includes multiple sub-matching relationships), where each of the multiple matching relationships is used to indicate a matching relationship between one first capability information and one second capability information, and the first matching relationship may indicate how the first capability information and the second capability information should be distributed, that is, the first network device may determine which first capability information should be selected by using the first matching relationship, and the second network device may determine which second capability information should be selected by using the second network device. In addition, a first capability information corresponds to a frequency band combination of the terminal device under the first communication system, and a second capability information corresponds to a frequency band combination of the terminal device under the second communication system, that is, a first capability information includes capability information of a frequency band combination of the terminal device under the first communication system, and a second capability information includes capability information of a frequency band combination of the terminal device under the second communication system, so that each matching relationship included in the first matching relationship actually indicates a matching relationship between the capability information of a frequency band combination of the terminal device under the first communication system and the capability information of a frequency band combination of the terminal device under the second communication system.
In the above paragraph, it is described how the first matching relationship indicates how the first capability information and the second capability information should be allocated, and how the first matching relationship indicates the capability division of the terminal device is described below. The manner of indicating the capability division condition of the terminal device by the first matching relationship may include multiple manners, and the first manner is described first, and then other manners are introduced later.
1. The first way.
In a first manner, the first matching relationship may include at least one first information, wherein one first information indicates a matching relationship between one first capability information and one second capability information. Or, as can be known from the foregoing, the first matching relationship includes multiple kinds of matching relationships, so that the number of the first information included in the first matching relationship is the same as the number of the matching relationships included in the first matching relationship, one of the first information is used to indicate one kind of matching relationship, and the first information and the matching relationships included in the first matching relationship are in a one-to-one correspondence relationship. For example, the first information may have at least two values, if the value of the first information is the first value, it indicates that the corresponding matching relationship is not supported, that is, the matching relationship between a first capability information and a second capability information corresponding to the first information is not supported, and if the value of the first information is the second value, it indicates that the corresponding matching relationship is supported, that is, the matching relationship between a first capability information and a second capability information corresponding to the first information is supported.
As a simpler example, for example, a first message may be implemented by 1 bit (bit), if the value of the 1 bit is 1, it indicates that the corresponding matching relationship is supported, and if the value of the 1 bit is 0, it indicates that the corresponding matching relationship is not supported. In this way, on the premise of ensuring that the first matching information can effectively indicate the matching relationship between the first capability information and the second capability information, the amount of information included in the first matching relationship is reduced as much as possible, thereby reducing the transmission overhead. Taking the first communication system as an E-UTRA system, the second communication system as an NR system, all the first capability information corresponding to the band combination supported by the terminal device in the E-UTRA system includes first capability information 1, first capability information 2, and first capability information 3, and all the second capability information corresponding to the band combination supported by the terminal device in the NR system includes first capability information 4, second capability information 5, and second capability information 6, for example, one first matching relationship may refer to table 1:
TABLE 1
Figure BDA0001654122790000251
Table 1 indicates that 1 in table 1 indicates first capability information 1, 2 indicates first capability information 2, 3 indicates first capability information 3, 4 indicates second capability information 4, 5 indicates second capability information 5, 6 indicates second capability information 6, wherein the first matching relationship includes first capability information and second capability information, which may be directly the first capability information and the second capability information, or may include an identifier of the corresponding first capability information (or referred to as a first capability information identifier) and an identifier of the corresponding second capability information (or referred to as a second capability information identifier), for example, an identification number (ID) of the capability information, for example, the first network device and the second network device may pre-store a corresponding relationship between the first capability information and the first capability information identifier and store a corresponding relationship between the second capability information and the second capability information identifier, the first matching relationship only needs to include the first capability information identifier and the second capability information identifier. In table 1, each of √ and × denotes the first information, for example, √ denotes that the first information takes the second value and × denotes that the first information takes the first value, or √ and × herein may be 1 and 0 instead, and the meaning is not changed. The first matching relationship shown in table 1 indicates a matching relationship between the first capability information of the terminal device in the E-UTRA system and the second capability information of the terminal device in the NR system, and also indicates which matching relationships can be supported by the terminal device and which matching relationships are not supported by the terminal device, so that both the first network device and the second network device can determine which matching relationships are optional according to the first matching relationship.
In addition to the above example, it is simpler that the first matching relationship may have another expression. Continuing with the example that the first communication system is an E-UTRA system, the second communication system is an NR system, all the first capability information corresponding to the band combination supported by the terminal device in the E-UTRA system includes first capability information 1, first capability information 2, and first capability information 3, and all the second capability information corresponding to the band combination supported by the terminal device in the NR system includes first capability information 4, second capability information 5, and second capability information 6, for another first matching relationship, refer to table 2:
TABLE 2
√ √ ×
√ √ √
√ × √
It can be seen that the first matching relationship shown in table 2 no longer includes the contents of the first capability information and the second capability information, but only includes the first information.
If this is the case, it is possible to specify in advance which first capability information and which second capability information each indicate a matching relationship between each of the first information in the first matching relationship. For example, a fixed order of all the first capability information of the terminal device in the first communication system may be specified, all the first capability information in the fixed order may be represented in a first sequence, and a fixed order of all the second capability information of the terminal device in the second communication system may be specified, and all the second capability information in the fixed order may be represented in a second sequence, for example, the first information included in the first matching relationship may be used to indicate a matching relationship between the first capability information in the first sequence and the first second capability information in the second sequence, the second first information included in the first matching relationship may be used to indicate a matching relationship between the first capability information in the first sequence and the second capability information in the second sequence, and so on.
Alternatively, it may not be necessary to specify the first sequence and the second sequence in advance, because the terminal device may also transmit at least one first capability information to at least one of the first network device and the second network device, and may also transmit at least one second capability information to at least one of the first network device and the second network device, then the first sequence may be determined according to a transmission order of the terminal device, for example, an order of the first capability information included in the first sequence is identical to an order of the first capability information transmitted by the terminal device, the first capability information transmitted by the terminal device first is arranged before the first sequence, and an order of the second capability information included in the second sequence is also identical, so that the first sequence and the second sequence may be obtained according to the transmission order of the terminal device, and likewise, for example, the first information included in the first matching relationship, is used to indicate a matching relationship between a first capability information in the first sequence and a first second capability information in the second sequence, the first matching relationship comprising a second first information is used to indicate a matching relationship between a first capability information in the first sequence and a second capability information in the second sequence, and so on. In addition, the content of the terminal device transmitting the at least one first capability information and the at least one second capability information will be described later, and thus will not be described in detail here.
The terminal device sends the first matching relation to the network device, and obviously, the transmission overhead can be further saved.
In a first manner, each piece of first capability information in at least one piece of first capability information included in the first matching relationship may represent all capability information of the terminal device in the first communication system, and each piece of second capability information in at least one piece of second capability information included in the first matching relationship may represent all capability information of the terminal device in the second communication system; or, in the first manner, each piece of first capability information in the at least one piece of first capability information included in the first matching relationship may represent a first part of capability information of the terminal device in the first communication system, and each piece of second capability information in the at least one piece of second capability information included in the first matching relationship may represent a first part of capability information of the terminal device in the second communication system. Then, if each of the at least one first capability information included in the first matching relationship represents a first part of capability information of the terminal device in the first communication system, each of the at least one second capability information included in the first matching relationship represents a first part of capability information of the terminal device in the second communication system, then the first matching relationship is equivalent to merely indicating a matching relationship between the first part of capability information of the terminal device in the first communication system and the first part of capability information of the terminal device in the second communication system, and the terminal device has other capability information in the first communication system, for example, also the third capability information, and similarly, the terminal device also has other capability information in the second communication system, for example, also the fourth capability information, the third capability information and the fourth capability information also need a certain matching relationship, and if the terminal device does not notify the network device of the matching relationship, the network device may not know how the capability of the terminal device is divided.
Therefore, if each of the at least one first capability information included in the first matching relationship in the first mode represents a first part of capability information of the terminal device in the first communication system, and each of the at least one second capability information included in the first matching relationship represents a first part of capability information of the terminal device in the second communication system, then the terminal device may send at least one third matching relationship to at least one of the first network device and the second network device in addition to the first matching relationship to the at least one of the first network device and the second network device, where the network device that sent the first matching relationship by the terminal device and the network device that sent the at least one third matching relationship by the terminal device may be the same network device, for example, the terminal device sends both the first matching relationship and the at least one third matching relationship to the first network device and the second network device, or both the first matching relationship and the at least one third matching relationship are sent to the first network device, or the terminal device sends the network device of the first matching relationship and the terminal device sends the network device of the at least one third matching relationship, or different network devices may be used, for example, the terminal device sends the first matching relationship to the first network device and the second network device, and sends the at least one third matching relationship to the first network device or the second network device, or the terminal device sends the first matching relationship to the first network device and sends the third matching relationship to the second network device, which is not limited in this specific embodiment. If only one network device receives the first matching relationship, the network device may send the first matching relationship to another network device, and similarly, if only one network device receives at least one third matching relationship, the network device may send at least one third matching relationship to another network device.
A third matching relationship corresponds to one of the first matching relationships, that is, a third matching relationship corresponds to a matching relationship between a first capability information and a second capability information. Moreover, the matching relationship in the first matching relationship corresponding to the third matching relationship is a matching relationship in which the value of the corresponding first information is the second value, that is, the matching relationship of one first capability information and one second capability information corresponding to each third matching relationship, and the values of the corresponding first information are the second values, it can be considered that the number of the third matching relationships is the same as the number of the first information whose value is the second value included in the first matching relationship. Furthermore, a third matching relationship may further include at least one second matching relationship, where one second matching relationship is a matching relationship between the third capability information and the fourth capability information, for example, one second matching relationship is a matching relationship between one third capability information and one fourth capability information.
That is, if the value of the first information corresponding to a certain matching relationship indicated by the first matching relationship is the second value, which indicates that the terminal device can support the matching relationship, the network device is likely to select to apply the matching relationship. The first matching relationship only indicates a matching relationship between the first part of capability information of the terminal device in the first communication system and the first part of capability information of the terminal device in the second communication system, and therefore, the terminal device needs to notify the network device of the matching relationship between the third capability information and the fourth capability information, that is, the network device is notified of the matching relationship between the second part of capability information of the terminal device in the first communication system and the second part of capability information of the terminal device in the second communication system, so that the network device can finally determine how the capabilities of the terminal device are divided.
For example, the first communication system is an E-UTRA system, the second communication system is an NR system, the frequency band combination supported by the terminal device in the first communication system includes a frequency band combination 1 and a frequency band combination 2, and the frequency band combination supported by the second communication system includes a frequency band combination 3, for example, a parameter set corresponding to the frequency band combination is divided into a first partial parameter and a second partial parameter according to whether the value of the parameter is variable, so that the number of the first capability information or the second capability information corresponding to one frequency band combination is 1, and the number of the third capability information or the fourth capability information corresponding to one frequency band combination is greater than or equal to 1. For example, the first capability information corresponding to the band combination 1 includes first capability information 1, the third capability information corresponding to the band combination 1 includes third capability information 1 and third capability information 2, the first capability information corresponding to the band combination 2 includes first capability information 2, the third capability information corresponding to the band combination 2 includes third capability information 3, the second capability information corresponding to the band combination 3 includes second capability information 1, the fourth capability information corresponding to the band combination 3 includes fourth capability information 1 and fourth capability information 2, the first capability information 1, the first capability information 2 and the second capability information 1 all include corresponding first partial capability information, and the third capability information 1, the third capability information 2, the third capability information 3, the fourth capability information 1 and the fourth capability information 2 all include corresponding second partial capability information. Then, the first matching relationship indicates a matching relationship between the first capability information and the second capability information, for example, the first matching information includes 2 kinds of matching relationships, which are a matching relationship between the first capability information 1 and the second capability information 1, and a matching relationship between the first capability information 2 and the second capability information 1, respectively, and the first matching information includes 2 pieces of first information, a first one of the first information indicates that the matching relationship between the first capability information 1 and the second capability information 1 is supported, a second one of the first information indicates that the matching relationship between the first capability information 2 and the second capability information 1 is not supported, and the first matching relationship refers to, for example, table 3:
TABLE 3
Figure BDA0001654122790000281
In addition to the first matching relationship, the terminal device further sends at least one third matching relationship to at least one of the first network device and the second network device, where the matching relationship in the first matching relationship corresponding to the third matching relationship needs to be a matching relationship in which the value of the first information is the second value, that is, the number of the third matching relationships is 1, the third matching relationship corresponds to the matching relationship between the first capability information 1 and the second capability information 1, and the third matching relationship includes a matching relationship between the third capability information of the frequency band combination 1 and the fourth capability information of the frequency band combination 3. The third matching relationship includes at least one second matching relationship, where each second matching relationship is a matching relationship between one third capability information and one fourth capability information, for example, the third matching relationship includes 3 second matching relationships, a first second matching relationship is a matching relationship between the third capability information 1 and the fourth capability information 1, a second matching relationship is a matching relationship between the third capability information 2 and the fourth capability information 1, and a third second matching relationship is a matching relationship between the third capability information 1 and the fourth capability information 2. Third matching relationship referring to table 4, for example, one row in table 4 represents a second matching relationship:
TABLE 4
Third capability information 1, fourth capability information 1
Third capability information 2, fourth capability information 1
Third capability information 1, fourth capability information 2
The third matching relationship may include specific third capability information and fourth capability information, for example, the third matching relationship shown in table 4 includes specific third capability information 1, third capability information 2, third capability information 3, fourth capability information 1 and fourth capability information 2, which is indicated more directly; alternatively, the third matching relationship may include only the identifier of the third capability information and the identifier of the fourth capability information, where the identifier of the third capability information is referred to as the third capability information identifier, for example, the ID of the third capability information, and the identifier of the fourth capability information is referred to as the fourth capability information identifier, for example, the ID of the fourth capability information.
Then, after obtaining the first matching relationship and the at least one third matching relationship, the first network device can more accurately determine the capability partition of the terminal device, and similarly, after obtaining the first matching relationship and the at least one third matching relationship, the second network device can also more accurately determine the capability partition of the terminal device.
In the first manner, if each of the at least one first capability information included in the first matching relationship indicates a first part of capability information of the terminal device in the first communication system, and each of the at least one second capability information included in the first matching relationship indicates a first part of capability information of the terminal device in the second communication system, then this embodiment further provides at least one third matching relationship for indicating a matching relationship between the third capability information and the fourth capability information. Then, the matching relationship between the third capability information and the fourth capability information may be notified to the network device in other forms besides being transmitted to the network device in the manner as shown in the first manner. A second way in which the first matching relationship indicates the capability division of the terminal device is described below, in which a way is described how to inform the network device of the matching relationship between the third capability information and the fourth capability information in another form.
2. The second way.
In the second mode, the first matching relationship may further include at least one first information, wherein one first information indicates a matching relationship between one first capability information and one second capability information. Similarly to the first manner, the first matching relationship includes a plurality of matching relationships, and then the number of the first information included in the first matching relationship is the same as the number of the matching relationships included in the first matching relationship, one of the first information is used to indicate one matching relationship, and the first information and the matching relationships included in the first matching relationship are in a one-to-one correspondence relationship.
In the first mode, the first information may indicate that the corresponding matching relationship is supported or not supported through the first value and the second value, and in the second mode, the first information may still set the first value, but may not set the second value, for example, if the value of the first information is the first value, it indicates that the corresponding matching relationship is not supported, that is, the matching relationship between one first capability information and one second capability information corresponding to the first information is not supported, and in addition, the first information may include at least one second matching relationship in addition to the first value, and indicates that the corresponding matching relationship is supported, that is, the matching relationship between one first capability information and one second capability information corresponding to the first information is supported. In this context, the first information can be understood to comprise either the first value or the at least one second matching relationship, or the at least one second matching relationship can also be regarded as a second value in a sense. One of the second matching relationships is a matching relationship between the third capability information and the fourth capability information, for example, one of the second matching relationships is a matching relationship between one of the third capability information and the fourth capability information. For the explanation of the at least one second matching relationship, reference is made to the above description of the at least one second matching relationship in the first way.
Continuing with the example condition of tables 3 and 4 in the first manner above, if the example condition is applied to the second manner, then the first matching relationship may refer to table 5:
TABLE 5
Figure BDA0001654122790000301
The first matching relationship shown in table 5 includes, in addition to the matching relationship between the first capability information and the second capability information, 3 second matching relationships, where the first second matching relationship is the matching relationship between the third capability information 1 and the fourth capability information 1, the second matching relationship is the matching relationship between the third capability information 2 and the fourth capability information 1, and the third second matching relationship is the matching relationship between the third capability information 1 and the fourth capability information 2.
It can be seen that, in the first matching relationship, the first information which is valued as the second value in the first manner is changed to include at least one second matching relationship, so that the matching relationship between the first capability information and the second capability information and the matching relationship between the third capability information and the fourth capability information can be sent to the network device together through the first matching relationship without sending additional matching relationships, which is beneficial to reducing the interaction process between devices and reducing the transmission overhead. And direct indication is carried out through the first matching relationship, and the mode is simpler.
The second matching relationship may include specific third capability information and fourth capability information, for example, the second matching relationship shown in table 5 includes specific third capability information 1, third capability information 2, third capability information 3, fourth capability information 1 and fourth capability information 2, which is indicated more directly; alternatively, the second matching relationship may include only the identifier of the third capability information and the identifier of the fourth capability information, where the identifier of the third capability information is referred to as the third capability information identifier, for example, the ID of the third capability information, and the identifier of the fourth capability information is referred to as the fourth capability information identifier, for example, the ID of the fourth capability information.
Tables such as table 2 to table 5 above are only examples given for easy understanding, and in practical applications, the first matching relationship may not be in a table form, for example, the first matching relationship may only include at least one first information, and then the first matching relationship may only be in a string of binary sequences, and the same may also be true for at least one third matching relationship, and not necessarily in a table form. The embodiment does not limit the specific implementation form of the first matching relationship and the at least one third matching relationship.
In this embodiment, the terminal device may send the first matching relationship to the network device through the first matching relationship message, and if the terminal device further needs to send at least one third matching relationship to the network device, the terminal device may send the at least one third matching relationship through the second matching relationship message. Of course, the terminal device may also send the first matching relationship and/or the at least one third matching relationship through other messages. For example, the first matching relationship message and the second matching relationship message may be dedicated signaling, for example, Radio link Control (RRC) messages, and the first matching relationship message and the second matching relationship message may include at least one container (container) of capability information and a corresponding RAT type, and the container of the capability information may include matching relationships, such as the first matching relationship and at least one third matching relationship. For example, the first matching relation message and the second matching relation message may include a RAT type parameter, and the RAT type parameter is set to eutra-nr, and further include a container containing EN-DC capability information.
In addition, as can be seen from the first manner or the second manner, if each piece of first capability information in at least one piece of first capability information included in the first matching relationship indicates a first part of capability information of the terminal device in the first communication system, and each piece of second capability information in at least one piece of second capability information included in the first matching relationship indicates a first part of capability information of the terminal device in the second communication system, the second matching relationship sent by the terminal device to the network device corresponds to a matching relationship between the first capability information and the second capability information that can be supported by the terminal device. For example, if the terminal device can support the matching relationship between the first part of the capability information of the band combination 1 in the first communication system and the first part of the capability information of the band combination 2 in the second communication system, and the network device may choose to apply the matching relationship, the terminal device may transmit the matching relationship between the second part of the capability information of the band combination 1 and the second part of the capability information of the band combination 2, that is, the matching relationship between the third capability information of the band combination 1 and the fourth capability information of the band combination 2 to the network device, so that the network device can determine the capability division of the terminal device, whereas if the terminal device does not support the matching relationship between the first part of the capability information of the band combination 1 in the first communication system and the first part of the capability information of the band combination 2 in the second communication system, the network device does not select to apply the matching relationship, and the terminal device does not need to send the matching relationship between the second part of the capability information of the band combination 1 and the second part of the capability information of the band combination 2 to the network device, thereby effectively saving transmission overhead.
Of course, the above two manners of indicating the capability division condition of the terminal device to the network device through the first matching relationship (or through the first matching relationship and the at least one third matching relationship) are merely examples, and the embodiment does not limit the manner of indicating the capability division condition of the terminal device to the network device.
It has been introduced that the terminal device is to send the first matching relationship and possibly also at least one third matching relationship to the network device, and then the terminal device is to send the matching relationships to the network device, and may also send at least one first capability information of the terminal device to the network device, and of course, may also send at least one second capability information to the network device, so that the network device may actually determine the capability partition of the terminal device according to the matching relationship sent by the terminal device.
The terminal device may send the at least one piece of first capability information to at least one of the first network device and the second network device. The at least one first capability information transmitted by the terminal device may be a complete set of first capability information that the terminal device has in the first communication system. For example, the at least one piece of first capability information sent by the terminal device to the network device includes first capability information 1 and first capability information 2 that can be supported in band combination 1, and first capability information 3 that can be supported in band combination 2. The frequency band combination 1 and the frequency band combination 2 are all frequency band combinations supported by the terminal device in the first communication system, the first capability information 1 and the first capability information 2 are all first capability information supported by the terminal device in the frequency band combination 1, and the first capability information 3 is all first capability information supported by the terminal device in the frequency band combination 2.
The terminal device sends at least one type of first capability information to the network device, where one possible manner is to send the first capability information corresponding to each possible frequency band combination in a form of a list, for example, if the terminal device supports 2 frequency band combinations in the first communication system, then for each frequency band combination in the 2 frequency band combinations, all the corresponding first capability information is sent in a form of a list. For example, the 2 frequency band combinations are frequency band combination 1 and frequency band combination 2, the first capability information corresponding to the frequency band combination 1 includes first capability information 1 and first capability information 2, and the first capability information corresponding to the frequency band combination 2 includes first capability information 3, then at least one type of first capability information sent by the terminal device may be as shown in table 6:
TABLE 6
Frequency band combination 1 First capability information 1, first capability information 2
Frequency band combination 2 First capability information 3
Or, the terminal device sends at least one type of first capability information to the network device, and another possible way is to send all the first capability information corresponding to all the frequency band combinations supported by the terminal device in the first communication system in a unified form of a list, and during sending, the corresponding relationship between the frequency band combinations and the first capability information may not be concerned any more. Continuing with the example of table 6, if in this manner the at least one first capability information sent by the terminal device may be as shown in table 7:
TABLE 7
First capability information 1
First capability information 2
First capability information 3
Of course, if this way is adopted, the correspondence between the band combination and the first capability information may have been notified to the network device in advance.
If the terminal device also needs to send at least one second capability information to the network device, the sending manner for the at least one second capability information is similar, and reference may be made to the introduction regarding the sending manner for the at least one first capability information.
For example, the terminal device may send at least one first capability information through a first capability report message, and send at least one second capability information through a second capability report message. Of course, the terminal device may also send the at least one first capability information and/or the at least one second capability information via other messages. For example, the first capability reporting message and the second capability reporting message may be dedicated signaling, for example, radio link control (RRC) messages, and a container (container) of at least one capability information and a corresponding RAT type may be included in the first capability reporting message and the second capability reporting message, and the container of the capability information may include capability information, such as the first capability information and the second capability information, and may also be understood as including capability parameters corresponding to the capability information. For example, the first capability report message may include a RAT type parameter, which may be set to eutra, and further include a container containing E-UTRA capability information, and the second capability report message may include a RAT type parameter, which may be set to NR, and further include a container containing NR capability information. Wherein, the network device of the terminal device sending the at least one first capability information and the network device of the terminal device sending the at least one second capability information may be the same network device, for example, the terminal device sends the at least one first capability information and the at least one second capability information to both the first network device and the second network device, or the network device of the terminal device sending the at least one first capability information and the network device of the terminal device sending the at least one second capability information may also be different network devices, for example, the terminal device sends the at least one first capability information to both the first network device and the second network device and sends the at least one second capability information to only the second network device, or the terminal device sends the at least one first capability information only to the first network device, and transmitting the at least one second capability information only to the second network device. If the terminal device sends the at least one first capability information to only one of the network devices, the network device may send the received at least one first capability information to another network device, and the same is true for the at least one second capability information.
It is also introduced in the foregoing that each of the at least one first capability information included in the first matching relationship may represent a first part of capability information of the terminal device under the first communication system, and then the terminal device may send at least one third capability information to the network device in addition to the at least one first capability information. The at least one third capability information sent by the terminal device may be a full set of third capability information that the terminal device has in the first communication system. For example, the at least one third capability information sent by the terminal device to the network device includes third capability information 1 and third capability information 2 that can be supported in band combination 1, and third capability information 3 and third capability information 4 that can be supported in band combination 2. The band combination 1 and the band combination 2 are all band combinations supported by the terminal device in the first communication system, the third capability information 1 and the third capability information 2 are all third capability information supported by the terminal device in the band combination 1, and the third capability information 3 and the third capability information 4 are all third capability information supported by the terminal device in the band combination 2.
The terminal device sends at least one kind of third capability information to the network device, where one possible manner is to send the third capability information corresponding to each possible frequency band combination in a form of a list, for example, if the terminal device supports 2 frequency band combinations in the first communication system, then for each frequency band combination in the 2 frequency band combinations, all the third capability information corresponding to the terminal device is sent in a form of a list. For example, the 2 frequency band combinations are frequency band combination 1 and frequency band combination 2, the third capability information corresponding to the frequency band combination 1 includes third capability information 1 and third capability information 2, and the third capability information corresponding to the frequency band combination 2 includes third capability information 3 and third capability information 2, then at least one kind of third capability information sent by the terminal device may be as shown in table 8:
TABLE 8
Frequency band combination 1 Third capability information 1, third capability information 2
Frequency band combination 2 Third capability information 3, third capability information 4
Or, the terminal device sends at least one third capability information to the network device, and another possible way is to send all the third capability information corresponding to all the frequency band combinations supported by the terminal device in the first communication system in a unified form of a list, and during sending, the corresponding relationship between the frequency band combinations and the third capability information may not be concerned any more. Continuing with the example of table 8, if in this way the terminal device transmits at least one third capability information, it can be as shown in table 9:
TABLE 9
Third capability information 1
Third capability information 2
Third capability information 3
Third capability information 4
Of course, if this way is adopted, the correspondence between the band combination and the third capability information may have been notified to the network device in advance.
It is further mentioned in the foregoing that, in the at least one second matching relationship, the third capability information identifier may be included, and then, in addition to sending the at least one third capability information to the network device, the terminal device also needs to send the at least one third capability information identifier corresponding to the at least one third capability information to the network device, so that after the network device obtains the at least one second matching relationship, it may be determined which third capability information is indicated by the third capability information identifier included in the at least one second matching relationship. For example, the terminal device may identify and transmit the at least one third capability information and the at least one third capability information to the network device, without separately transmitting them, so as to reduce transmission overhead. In the sending, the third capability information may be sent in a corresponding form, taking table 8 as an example, if the terminal device further sends the third capability information identifier together, the at least one third capability information and the at least one third capability information identifier sent by the terminal device may be as shown in table 10:
watch 10
Figure BDA0001654122790000341
Taking table 8 as an example, at least one third capability information and at least one third capability information identifier sent by the terminal device may be as shown in table 11:
TABLE 11
Third capability information 1, third capability information identification 1
Third capability information 2, third capability information identification 2
Third capability information 3, third capability information identification 3
Third capability information 4, third capability information identification 4
It can be seen that, regardless of the transmission mode of the terminal device shown in table 10 or table 11, the third capability information and the third capability information identifier are all in a one-to-one correspondence relationship, and the network device can determine which third capability information is indicated by one third capability information identifier.
In addition, each piece of second capability information in the at least one piece of second capability information included in the first matching relationship may represent a second part of capability information of the terminal device under the first communication system, and then, the terminal device may send at least one piece of fourth capability information to the network device in addition to the at least one piece of second capability information to the network device. If the terminal device is to transmit at least one fourth capability information to the network device, the transmission manner for the at least one fourth capability information is similar, and reference may be made to the introduction regarding the transmission manner for the at least one third capability information. Of course, if the at least one second matching relationship includes the fourth capability information identifier, the terminal device sends at least one fourth capability information to the network device, and also sends at least one fourth capability information identifier corresponding to the at least one fourth capability information to the network device, and a manner in which the terminal device sends the fourth capability information identifier may refer to a manner in which the terminal device sends the third capability information identifier.
For example, the terminal device may send the at least one third capability information (or the at least one third capability information and the at least one third capability information identifier) through a third capability reporting message, and send the at least one fourth capability information (or the at least one fourth capability information and the at least one fourth capability information identifier) through a fourth capability reporting message. Of course, the terminal device may also send the at least one third capability information and/or the at least one fourth capability information through other messages. For example, the third capability reporting message and the fourth capability reporting message may be dedicated signaling, for example, radio link control (RRC) messages, and a container (container) of the third capability reporting message and the fourth capability reporting message, which may include at least one capability information and a corresponding RAT type, and the container of the capability information may include capability information, such as the third capability information and the fourth capability information, and may also be understood as including capability parameters corresponding to the capability information. For example, the third capability report message may include a RAT type parameter, which may be set to eutra, and further include a container containing E-UTRA capability information; or, the fourth capability report message may include a RAT type parameter, where the RAT type parameter may be set to NR, and further includes a container containing NR capability information.
Wherein, the network device of the terminal device sending the at least one third capability information and the network device of the terminal device sending the at least one fourth capability information may be the same network device, for example, the terminal device sends the at least one third capability information and the at least one fourth capability information to both the first network device and the second network device, or the network device of the terminal device sending the at least one third capability information and the network device of the terminal device sending the at least one fourth capability information may also be different network devices, for example, the terminal device sends the at least one third capability information to both the first network device and the second network device and sends the at least one fourth capability information to only the second network device, or the terminal device sends the at least one third capability information only to the first network device, and transmitting the at least one fourth capability information only to the second network device. If the terminal device sends at least one third capability information to only one of the network devices, the network device may send the received at least one third capability information to another network device, and the same is true for at least one fourth capability information.
As can be seen from the foregoing description, each of the first network device and the second network device may obtain the first capability information and the second capability information of the terminal device, when the first capability information is the first part capability information of the terminal device in the first communication system, each of the first network device and the second network device may further obtain the third capability information of the terminal device, when the second capability information is the first part capability information of the terminal device in the second communication system, each of the first network device and the second network device may further obtain the fourth capability information of the terminal device, and each of the first network device and the second network device may obtain the first matching relationship and may further obtain at least one third matching relationship. The master network device of the terminal device of the first network device and the second network device may determine how to allocate the capabilities of the terminal device, the master network device may select a matching relationship from the first matching relationships, that is, a matching relationship between one of the first capability information and one of the second capability information, and allocate the capabilities of the terminal device according to the matching relationship, and correspondingly, if there is at least one third matching relationship, the matching relationship may correspond to a third matching relationship, and the master network device may also allocate the capabilities of the terminal device according to the third matching relationship.
For example, if the primary network device is the first network device, the primary network device assigns one of the selected first matching relationships indicating one of the first capabilities information to the primary network device, and assigns one of the selected first matching relationships indicating one of the second capabilities information to the secondary network device. If the matching relationship corresponds to a third matching relationship, the primary network device further selects a second matching relationship among the third matching relationships, assigns a third capability information indicated by the second matching relationship to the primary network device, and assigns a fourth capability information indicated by the second matching relationship to the secondary network device.
Or, the primary network device is the second network device, the primary network device determines to assign one of the selected first matching relationships indicated one of the second capability information to the primary network device, and determines to assign one of the selected first matching relationships indicated one of the first capability information to the secondary network device. If the matching relationship corresponds to a third matching relationship, the primary network device further selects a second matching relationship among the third matching relationships, assigns a fourth capability information indicated by the second matching relationship to the primary network device, and assigns a third capability information indicated by the second matching relationship to the secondary network device.
The selection of a first matching relationship from the first matching relationships and how to select a second matching relationship from the third matching relationships is relevant to the specific implementation of the primary network device. For example, the selection may be random, or the selection may be based on the current network quality, etc., and the specific selection manner is not limited.
The master network device determines the capability division of the terminal device after selecting a matching relationship from the first matching relationships, or after selecting a matching relationship from the first matching relationships and selecting a second matching relationship from a third matching relationship corresponding to the matching relationship. The primary network device may then inform the secondary network device about the capability partitioning of the terminal device, e.g. the primary network device may send a notification message to the secondary network device indicating the capability partitioning of the terminal device. Wherein, the main network device may directly send the capability information of the terminal device allocated to the auxiliary network device through the notification message, and then the auxiliary network device may directly obtain the capability information of the terminal device after receiving the notification message, so as to directly call the terminal device according to the obtained capability information of the terminal device, or the main network device may also simply notify the auxiliary network device of the identifier of one of the selected first matching relationships through the notification message, or notify the auxiliary network device of the identifier of one of the selected first matching relationships through the notification message, and notify the identifier of one of the selected second matching relationships in one of the selected third matching relationships corresponding to the matching relationships, and then the auxiliary network device may query the first matching relationships after receiving the notification message, or inquiring the first matching relation and the at least one third matching relation to determine the capacity division condition of the terminal equipment, wherein in the notification mode, the information amount of the notification message is small, so that the transmission overhead is small.
Or, the primary network device may determine capability information of the terminal device applied by the primary network device, for example, if it is determined that the primary network device is the first network device, the primary network device determines the applied first capability information, then the primary network device may send the determined first capability information or a first capability information identifier of the determined first capability information to the secondary network device, and after receiving the first capability information or the first capability information identifier, the secondary network device determines, according to the first matching relationship, that there are one or more matching relationships associated with the first capability information or the first capability information in the first matching relationship, then if there is only one matching relationship associated with the first capability information or the first capability information in the first matching relationship, the secondary network device determines to select the matching relationship and determines that the second capability information associated with the matching relationship is the second capability information of the terminal device applied by the secondary network device, if there are a plurality of matching relationships associated with the first capability information or the first capability information in the first matching relationship, the secondary network device may select one of the matching relationships, so as to determine that the second capability information associated with the selected matching relationship is the second capability information of the terminal device applied by the secondary network device. For example, the secondary network device may be selected according to the network quality and other factors, or randomly selected, and the specific selection manner is not limited in this embodiment. In this way, both the primary network device and the secondary network device have a certain subjective initiative and both have a certain option.
By the method provided by the embodiment, the terminal device can send the matching relationship between the capability information of the terminal device to the network device, so that the network device can determine the capability division of the terminal device according to the obtained matching relationship to schedule the terminal device. Therefore, the terminal equipment can work normally, and the network equipment can also schedule the terminal equipment normally.
As described above, the first capability information may include all capability information of the terminal device in the first communication system, and it is understood that one first capability information is a value of a parameter set corresponding to a frequency band combination supported by the terminal device in the first communication system, and if the frequency band combination corresponds to a plurality of first capability information, each of the first capability information is a value of the parameter set, that is, each of the first capability information includes values of all parameters in the parameter set. However, it is also introduced in the foregoing that, in the parameters included in the parameter set corresponding to a frequency band combination, values of some parameters may be fixed, and then the values of the parameters are the same for any first capability information corresponding to the frequency band combination, which is equivalent to that, if the terminal device sends a plurality of first capability information corresponding to the frequency band combination to the network device, for the parameters whose values are not changed, the same information is sent multiple times, so that repeated sending is actually caused, and a large overhead is also brought.
In order to solve the technical problem, an embodiment of the present application further provides a communication method, by which transmission overhead can be reduced as much as possible, and a situation of repeated transmission can also be reduced. Fig. 4A is a flowchart of the method. The embodiment shown in fig. 4A may be continuously applied to the application scenario shown in fig. 2, for example, the network device in the following may be the first network device or the second network device in fig. 2, or the embodiment shown in fig. 4A may also be applied to the application scenario shown in fig. 4B, where the application scenario shown in fig. 4B includes a terminal device and a network device, that is, the embodiment shown in fig. 4A may also be applied to a scenario where the terminal device only accesses one network device. For example, in the scenario shown in fig. 4B, the network device operates in an E-UTRA system, that is, the network device is an E-UTRA network device, or operates in an NR system, that is, the network device is an NR network device, but is not limited thereto, and the network device may be other network devices. In the following description, the application scenario shown in fig. 4B continues to be exemplified by the method provided in the embodiment of the present application.
S41, the terminal device sends first capability information to the network device, and the network device receives the first capability information from the terminal device, wherein the first capability information is first part capability information of first capability of the terminal device;
s42, the terminal device sends at least one piece of second capability information to the network device, and the network device receives at least one piece of second capability information from the terminal device, where the second capability information is a second part of capability information of the first capability, the first capability is a capability of the terminal device in a radio access technology, and one piece of the first capability information and the at least one piece of second capability information form all capability information of the first capability.
In this embodiment, for example, the terminal device and the network device both operate in the first communication system, the radio access technology is a radio access technology applied to the first communication system, and the total capability information corresponding to the first capability is the total capability information of the terminal device in the first communication system. For example, if the first communication system is an NR system, the radio access technology applied by the first communication system is an NR technology, or if the first communication system is an E-UTRA system, the radio access technology applied by the first communication system is an E-UTRA technology.
The first capability information includes a first portion of capability information of the first capability of the terminal device, and not all capability information of the first capability of the terminal device. For a set of parameters corresponding to a combination of frequency bands, the set of parameters may be divided into at least two parts, each of which may include at least one parameter. The dividing manner may also be multiple, for example, the dividing manner may be random, or the dividing manner may be divided according to importance of the parameter, for example, dividing the more important parameter into one part, or dividing the more important parameter according to whether a value of the parameter changes, and the specific dividing manner is not limited. The following description focuses on the manner in which the parameter is divided according to whether the value of the parameter changes.
For example, values of some parameters are not changed, that is, values of some parameters in a parameter set corresponding to a band combination may be fixed, and values of some parameters may be changed, for example, carrier aggregation band levels, which may be different levels such as a, b, and c … …. For example, according to the parameter value, the parameters included in the parameter set are divided into a first part of parameters and a second part of parameters, where the first part of parameters includes parameters whose values do not change, and thus the first part of parameters may also be referred to as fixed parameters, the capacity represented by the first part of parameters may also be referred to as fixed capacity, and the second part of parameters includes parameters whose values change, and thus the second part of parameters may also be referred to as variable parameters, and the capacity represented by the second part of parameters may also be referred to as variable capacity. For example, the capability indicated by the first partial parameter is a first partial capability, the capability indicated by the second partial parameter is a second partial capability, a first capability information is, for example, a value of the first partial parameter corresponding to a frequency band combination, and a second capability information is a value of the second partial parameter corresponding to a frequency band combination.
Of course, the number of the parameter set to be divided into the number of parts is greater than or equal to 2, and the number may be defined by a protocol, or may be specified by a terminal device or a network device, without limitation.
The division is continued by taking as an example the case whether the value of the parameter will change. As can be seen from the foregoing description, for each frequency band combination supported by the terminal device in the first communication system, one piece of first capability information may correspond to one or more pieces of second capability information, and then the first capability information sent by the terminal device in S41 may include the first capability information corresponding to all frequency band combinations supported by the terminal device in the first communication system, that is, the number of the first capability information sent by the terminal device in S41 may also be one or more. Similarly, the at least one piece of second capability information sent by the terminal device in S42 may also include second capability information corresponding to all frequency band combinations supported by the terminal device in the first communication system, so that the network device can acquire all capability information of the terminal device in the first communication system, that is, acquire the first capability of the terminal device.
Because the first capability information sent to the network device includes first capability information corresponding to all band combinations supported by the terminal device in the first communication system, and the at least one piece of second capability information sent to the network device also includes second capability information corresponding to all band combinations supported by the terminal device in the first communication system, there should be a certain correspondence between the first capability information and the second capability information, and this correspondence is embodied by the band combinations. Then, the terminal device may further send capability relationship information to the network device, where the capability relationship information indicates at least one matching relationship between the first capability information and the at least one second capability information, and the network device may determine the matching relationship between the first capability information and the at least one second capability information after receiving the capability relationship information from the terminal device. Taking a way of dividing according to whether the value of the parameter changes or not as an example, each matching relationship therein represents a matching relationship between one piece of first capability information and one or more pieces of second capability information.
For example, the terminal device corresponds to two frequency band combinations, namely, a frequency band combination 1 and a frequency band combination 2 under the first communication system, wherein the frequency band combination 1 corresponds to one piece of first capability information, is a first capability information 1, and corresponds to 2 pieces of second capability information, namely, a second capability information 1 and a second capability information 2, the frequency band combination 2 corresponds to one piece of first capability information, is a first capability information 2, and corresponds to 3 pieces of second capability information, namely, a second capability information 3, a second capability information 4, and a second capability information 5, then the first capability information sent to the network device by the terminal device in S41 includes the first capability information 1 and the first capability information 2, and at least one piece of second capability information sent to the network device in S42 includes the second capability information 3, the second capability information 4, and the second capability information 5. In addition, the terminal device may also send capability relationship information to the network device, and the capability relationship information can indicate a matching relationship between the first capability information 1 and the second capability information 1 and 2, and indicate a matching relationship between the first capability information 2 and the second capability information 3, the second capability information 4, and the second capability information 5.
Taking the way of dividing according to the situation that whether the value of the parameter changes or not as an example, the second capability information that the terminal device needs to send to the network device may be more. Then, as another embodiment, the terminal device may send at least one second capability information identifier to the network device instead of the at least one second capability information, where one second capability information identifier is used to indicate one second capability information. That is to say, the terminal device sends the second capability information identifier instead of sending the second capability information, so that the network device can also determine the at least one piece of second capability information after receiving the at least one piece of second capability information identifier, and the information amount of the second capability information identifier is generally much smaller than that of the second capability information, by which means the transmission overhead can be reduced. Of course, the precondition for this method is that the network device obtains the corresponding relationship between the at least one piece of second capability information and the at least one piece of second capability information identifier in advance, that is, the network device already knows in advance what second capability information the second capability information identifier is used to indicate, so that the network device can determine the corresponding at least one piece of second capability information after receiving the at least one piece of second capability information identifier. For example, the terminal device may send the corresponding relationship between the at least one piece of second capability information and the at least one piece of second capability information identifier to the network device in advance, or the corresponding relationship between the at least one piece of second capability information and the at least one piece of second capability information identifier may be predefined by a protocol.
Similarly, for the first capability information, the terminal device may send the first capability information identifier to the network device instead of the first capability information, where one first capability information identifier is used to indicate one first capability information. That is to say, the terminal device sends the first capability information identifier instead of sending the first capability information, so that the network device can also determine the first capability information after receiving the first capability information identifier, and the information amount of the first capability information identifier is generally much smaller than that of the first capability information, by which way, the transmission overhead can be further reduced. Of course, the precondition of this method is that the network device obtains the corresponding relationship between the first capability information and the first capability information identifier in advance, that is, the network device already knows what first capability information the first capability information identifier is used to indicate in advance, so that the network device can determine the corresponding first capability information after receiving the first capability information identifier. For example, the terminal device may transmit the correspondence between the first capability information and the first capability information identifier to the network device in advance, or the correspondence between the first capability information and the first capability information identifier may be predefined by a protocol.
The terminal device may send at least one second capability information identifier to the network device and send the first capability information identifier to the network device, or the terminal device may send at least one second capability information identifier to the network device and send the first capability information to the network device, or the terminal device may send at least one second capability information to the network device and send the first capability information identifier to the network device, or the terminal device may send at least one second capability information to the network device and send the first capability information to the network device, which is not limited in this specific embodiment.
It should be noted that, if the terminal device sends the at least one second capability information identifier to the network device and sends the first capability information identifier to the network device, the capability relationship information indicates at least one matching relationship between the first capability information identifier and the at least one second capability information identifier. That is, the type of capability relation information indication is related to the type of information transmitted by the terminal device.
For the concept of the first capability information, the sending method (for example, what message to send), and the like, reference may be made to the related description of the first capability information or the second capability information in the embodiment shown in fig. 3, and for the concept of the second capability information, the sending method (for example, what message to send), and the like, reference may be made to the related description of the third capability information or the fourth capability information in the embodiment shown in fig. 3, and repeated parts are not repeated again.
Taking the example of dividing the parameter set according to the value conditions of the parameters and dividing the parameter set into the first part of parameters and the second part of parameters, it can be seen that the first part of parameters are fixed parameters, and for a band combination, the first part of parameters only correspond to one value set of the first part of parameters, for example, for the first communication system, only correspond to one piece of first capability information, so that for the parameters with unchanged values in the parameter set, the values of the parameters are sent to the network device only once without being sent for multiple times, the information amount sent repeatedly is reduced, and the overhead is saved. The second part of parameters are variable parameters, and for a band combination, the second part of parameters may correspond to at least one value set of the second part of parameters, for example, for the first communication system, the second part of parameters correspond to at least one piece of second capability information.
