Description

Method and equipment for configuring carrier

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method and a device for configuring a carrier.

Background

A Packet Data Convergence Protocol (PDCP) layer data retransmission mechanism is introduced in a fifth generation mobile communication technology (5G) system, and a general idea is that, if a duplicate transmission function of a PDCP layer is configured and activated for a radio bearer, each original data packet generated by the PDCP layer needs to be copied into a same data packet, and then the original data packet and the copied data packet are delivered by the PDCP layer to two different Radio Link Control (RLC) entities, and are transmitted to a Media Access Control (MAC) layer through different logical channels.

In order to ensure the reliability of data transmission, the original data packet and the copied data packet transmitted to the MAC layer cannot be transmitted through the same MAC Protocol Data Unit (PDU), because only through transmission of different MAC PDUs, the transmission of another MAC PDU cannot be affected by the loss of one MAC PDU, which is equivalent to that the reliability is doubled. Therefore, two RLC entities can transmit two data packets to different MAC entities through different logical channels, and finally form two MAC PDUs for transmission on different carriers. This involves two logical channels and two carriers, and in order to increase the transmission success rate, generally, corresponding transmission relationships can be set for the logical channels and the carriers.

The corresponding transmission relationship exists not only in the scenario of the repeated transmission of the PDCP layer but also in the scenario of the repeated transmission of the non-PDCP layer. In the prior art, after the repeated transmission function of the PDCP layer is deactivated, all the corresponding transmission relationships between the logical channels and the carriers are released, so that the terminal device cannot use the corresponding transmission relationships between the logical channels and the carriers in some scenarios of non-repeated transmission.

Disclosure of Invention

The embodiment of the application provides a method and equipment for configuring carriers, which are used for continuously applying corresponding transmission relations between logical channels and carriers set for other scenes after a repeated transmission function of a PDCP layer is deactivated.

In a first aspect, a first method for configuring a carrier is provided, where the method includes: determining a first parameter of a first logical channel, wherein the first parameter is used for indicating that a carrier used for transmitting data in the first logical channel is a first carrier, the first logical channel belongs to a first radio bearer, the first radio bearer is configured with a repeat transmission function, and the repeat transmission function is activated, and the first parameter is different from a second parameter, wherein the second parameter is used for indicating that a carrier used for transmitting data in the second logical channel is a second carrier, the second logical channel belongs to a second radio bearer, the second radio bearer is not configured with the repeat transmission function, or the second radio bearer is configured with the repeat transmission function, but the repeat transmission function is not activated; sending a first message, the first message including the first parameter.

In this embodiment of the present application, two different parameters, that is, a first parameter and a second parameter, may be configured for the retransmission function and the non-retransmission function, so that after the retransmission function is deactivated, only the first parameter corresponding to the retransmission function may be deleted, and the second parameter configured for the non-retransmission function may be continuously reserved, that is, the corresponding transmission relationship between the logical channel and the carrier determined according to the second parameter may continuously exist, and therefore, after the retransmission function is deactivated, the corresponding transmission relationship between the logical channel and the carrier configured for the non-retransmission function may be continuously applied.

The data in the second logical channel is transmitted only by the second carrier, which is indicated by the second parameter, that is, after the repeated transmission function of the first radio bearer is deactivated, the second parameter will continue to exist, so the corresponding transmission relationship between the logical channel and the carrier indicated by the second parameter will continue to be used.

In addition, in this embodiment of the present application, after the repeated transmission function of the first radio bearer is deactivated, the first parameter may be deleted, or the first parameter may also exist continuously, that is, the corresponding transmission relationship between the logical channel and the carrier indicated by the first parameter may also be used continuously, which is not limited specifically.

With reference to the first aspect, in a possible implementation manner of the first aspect, the first logical channel and the second logical channel are the same logical channel.

In a third aspect, a third method for configuring a carrier is provided, which includes: determining a first value of a parameter of a first logical channel, where the first value is used to indicate that a carrier used for transmitting data in the first logical channel is a first carrier, the first logical channel belongs to a first radio bearer, the first radio bearer is configured with a repeat transmission function, and the repeat transmission function is activated, the first value and a second value of the parameter are determined according to different value rules, the second value is used to indicate that a carrier used for transmitting data in a second logical channel is a second carrier, the second logical channel belongs to a second radio bearer, the second radio bearer is not configured with a repeat transmission function, or the second radio bearer is configured with the repeat transmission function, but the repeat transmission function is not activated; and sending a first message, wherein the first message comprises the first value of the parameter.

The method may be performed by a third communication device, for example, a network device or a communication device capable of supporting a network device to implement the functions required by the method, or for example, a chip capable of being disposed in a network device, for example, a base station.

In this embodiment of the present application, different values of a parameter, that is, a first value and a second value, may be configured for a retransmission function and a non-retransmission function, where the first value and the second value are determined according to different value rules, for example, or the first value and the second value are applied to different scenarios, so that after the retransmission function is deactivated, only the first value corresponding to the retransmission function may be deleted, and the second value configured for the non-retransmission function may be continuously retained, that is, a corresponding transmission relationship between a logical channel and a carrier determined according to the second value may continue to exist, so that after the retransmission function is deactivated, the corresponding transmission relationship between the logical channel and the carrier configured for the non-retransmission function may continue to be applied.

It can be seen that in the embodiment of the present application, two different values of the same parameter are configured for the retransmission function and the non-retransmission function, and the two values are not confused with each other and are not overlapped with each other, so that the first value configured for the retransmission function and the second value configured for the non-retransmission function are independent from each other, and the second value configured for the non-retransmission function is not deleted because the retransmission function is deactivated, so that the corresponding transmission relationship between the logical channel configured for the non-retransmission function and the carrier can be continuously used.

In this embodiment, the first logical channel and the second logical channel may be the same logical channel, that is, the same logical channel may also be configured with different values of the same parameter, so as to distinguish different scenarios applied by the logical channel.

In a fourth aspect, a fourth method for configuring a carrier is provided, the method comprising: receiving a first message, where the first message includes a first value of a parameter of a first logical channel, where the first value is used to indicate that a carrier used for transmitting data in the first logical channel is a first carrier, the first logical channel belongs to a first radio bearer, the first radio bearer is configured with a repeat transmission function, and the repeat transmission function is activated, the first value and a second value of the parameter are determined according to different value rules, the second value is used to indicate that a carrier used for transmitting data in a second logical channel is a second carrier, the second logical channel belongs to a second radio bearer, the second radio bearer is not configured with a repeat transmission function, or the second radio bearer is configured with the repeat transmission function, but the repeat transmission function is not activated; and determining to transmit the data in the first logic channel by using only a first carrier according to the first value.

With reference to the fourth aspect, in a possible implementation manner of the fourth aspect, the method further includes: and after the repeated transmission function of the first radio bearer is deactivated, only using the second carrier to transmit the data in the second logic channel.

With reference to the fourth aspect, in a possible implementation manner of the fourth aspect, the first logical channel and the second logical channel are the same logical channel.

For a technical effect of the fourth aspect or any one of its possible implementations, reference may be made to the introduction of the third aspect or various possible implementations of the third aspect.

In a fifth aspect, a fifth method for configuring a carrier is provided, the method including: determining indication information, where the indication information is used to indicate whether a terminal device continues to transmit data in a first logical channel only by using a first carrier after a repeated transmission function of a first radio bearer is deactivated, where the first logical channel belongs to the first radio bearer; and sending the indication information.

The method may be performed by a fifth communication device, for example, a network device or a communication device capable of supporting a network device to implement the functions required by the method, or for example, a chip capable of being disposed in a network device, for example, a base station.

In the method, for the corresponding transmission relationship between the logical channel and the carrier under the first radio bearer, it can be directly determined whether to continue to use the corresponding transmission relationship after the repeated transmission function of the first radio bearer is deactivated, and then the terminal device can determine whether to continue to use the corresponding transmission relationship after the repeated transmission function of the first radio bearer is deactivated according to the indication information, which is simpler in mode. Moreover, the corresponding transmission relationship between the logical channel and the carrier may be set for the repeated transmission function of the first radio bearer, or may also be set for the non-repeated transmission function of the first radio bearer, and it is clear that, no matter why the corresponding transmission relationship set by the function is set, the terminal device may be instructed whether to continue to use after the repeated transmission function of the first radio bearer is deactivated, which is more flexible.

With reference to the fifth aspect, in a first possible implementation manner of the fifth aspect, the sending the indication information includes: sending a first message, where the first message includes the indication information, and the first message is used to configure a duplicate transmission function of the first radio bearer, or the first message is used to deactivate the duplicate transmission function of the first radio bearer.

When configuring the retransmission function for the first radio bearer, the configuration is generally performed through a message, such as an RRC message. The deactivation of the duplicate transmission function for the first radio bearer is also typically indicated by a message, such as an RRC message. In the embodiment of the application, the indication information can be included in any one of the two messages, so that the indication information can be transmitted through the existing message without using an additional message, and the transmission resource is saved.

With reference to the fifth aspect, in a first possible implementation manner of the fifth aspect, the sending the indication information includes: sending an RRC message, where the RRC message is used to instruct to deactivate a duplicate transmission function of the first radio bearer, and to instruct to transmit data in the first logical channel only by using the first carrier after the duplicate transmission function of the first radio bearer is deactivated; or, sending a MAC CE, where the MAC CE is configured to instruct to deactivate a duplicate transmission function of the first radio bearer, and instruct to transmit data in the first logical channel by using the first carrier or another carrier after the duplicate transmission function of the first radio bearer is deactivated; or, sending a MAC CE, where the MAC CE is configured to instruct to deactivate a retransmission function of the first radio bearer, and is configured to instruct to transmit data in the first logical channel only by using the first carrier after the retransmission function of the first radio bearer is deactivated; or, sending an RRC message, where the RRC message is used to instruct to deactivate the duplicate transmission function of the first radio bearer, and is used to instruct to transmit the data in the first logical channel by using the first carrier or another carrier after the duplicate transmission function of the first radio bearer is deactivated.

In this implementation, the indication information is implicitly indicated. When the duplicate transmission function is instructed to be deactivated for the first radio bearer, the duplicate transmission function may be instructed through an RRC message or may be instructed through a MAC CE, so that the instruction may be implicitly performed through the two messages. For example, the protocol or the network device is predefined, if an RRC message is sent when it is indicated that the duplicate transmission function is deactivated for the first radio bearer, it is indicated that the corresponding transmission relationship between the first carrier and the first logical channel is no longer used after the duplicate transmission function of the first radio bearer is deactivated, and if a MAC CE is sent when it is indicated that the duplicate transmission function is deactivated for the first radio bearer, it is indicated that the corresponding transmission relationship between the first carrier and the first logical channel is continuously used after the duplicate transmission function of the first radio bearer is deactivated.

In a sixth aspect, a sixth method for configuring a carrier is provided, the method comprising: receiving indication information; and determining whether to continue to transmit the data in the first logical channel by using the first carrier only after the repeated transmission function of the first radio bearer is deactivated according to the indication information, wherein the first logical channel belongs to the first radio bearer.

The method may be performed by a sixth communication device, for example a terminal device or a communication device capable of supporting a terminal device to implement the functions required by the method, or for example a chip capable of being provided in a terminal device.

With reference to the sixth aspect, in a first possible implementation manner of the sixth aspect, the receiving the indication information includes: receiving a first message, where the first message includes the indication information, and the first message is used to configure a repeat transmission function of the first radio bearer layer, or the first message is used to deactivate the repeat transmission function of the first radio bearer.

With reference to the sixth aspect, in a first possible implementation manner of the sixth aspect, the receiving the indication information includes: receiving an RRC message, wherein the RRC message is used for indicating that the repeated transmission function of the first radio bearer is deactivated and for indicating that only the first carrier is used for transmitting the data in the first logical channel after the repeated transmission function of the first radio bearer is deactivated; or, receiving a MAC CE, where the MAC CE is configured to instruct to deactivate a duplicate transmission function of the first radio bearer, and instruct to transmit data in the first logical channel by using the first carrier or another carrier after the duplicate transmission function of the first radio bearer is deactivated; or, receiving a MAC CE, where the MAC CE is configured to instruct to deactivate a duplicate transmission function of the first radio bearer, and to instruct to transmit data in the first logical channel only with the first carrier after the duplicate transmission function of the first radio bearer is deactivated; or, receiving an RRC message, where the RRC message is used to instruct to deactivate the duplicate transmission function of the first radio bearer, and is used to instruct to transmit the data in the first logical channel by using the first carrier or another carrier after the duplicate transmission function of the first radio bearer is deactivated.

For a technical effect of the sixth aspect or any one of its possible implementations, reference may be made to the introduction of the fifth aspect or its various possible implementations.

In a seventh aspect, a seventh method for configuring a carrier is provided, where the method includes: receiving a deactivation message, wherein the deactivation message is used for indicating that the repeated transmission function of the first radio bearer is deactivated; determining whether a parameter indicating that data in a first logical channel is transmitted using only a first carrier is configured for a repeat transmission function of the first radio bearer, the first logical channel belonging to the first radio bearer; transmitting data in the first logical channel using only the first carrier if the parameter is not configured for a repeat transmission function of the first radio bearer.

The method may be performed by a seventh communication means, for example a terminal device or a communication means capable of supporting a terminal device to implement the functions required for the method, or for example a chip capable of being provided in a terminal device.

For example, after receiving the deactivation message, the terminal device may determine by itself whether the corresponding transmission relationship between the first carrier and the first logical channel is configured for the repetitive transmission function of the first radio bearer, and if the corresponding transmission relationship between the first carrier and the first logical channel is not configured for the repetitive transmission function of the first radio bearer, the corresponding transmission relationship between the first carrier and the first logical channel may be further used after the repetitive transmission function of the first radio bearer is deactivated, and reconfiguration is not required, so that the operation process of the device is saved.

With reference to the seventh aspect, in a first possible implementation manner of the seventh aspect, the determining whether a parameter indicating that data in a first logical channel is transmitted only by using a first carrier is configured for a repeat transmission function of the first radio bearer includes: and determining whether the parameter is included in a message for configuring a retransmission function for the first radio bearer, wherein if the parameter is included in the message for configuring the retransmission function for the first radio bearer, it is determined that the parameter is configured for the retransmission function of the first radio bearer, and otherwise, it is determined that the parameter is not configured for the retransmission function of the first radio bearer.

A specific judgment method is provided. Generally, if a corresponding transmission relationship between a logical channel and a carrier is to be configured for the retransmission function of the first radio bearer, the corresponding transmission relationship is configured in a message for configuring the retransmission function for the first radio bearer, so that if the parameter is included in the message for configuring the retransmission function for the first radio bearer, the parameter may be considered to be configured for the retransmission function of the first radio bearer, and if the parameter is not included in the message for configuring the retransmission function for the first radio bearer, the corresponding transmission relationship may be configured in a message for configuring the retransmission function for the first radio bearer. In this way, it can be simply determined whether the parameter is configured for the repeat transmission function of the first radio bearer.

By way of example and not limitation, in the embodiments of the present application, the terminal device may also be a wearable device. Wearable equipment can also be called wearable intelligent equipment, is the general term of applying wearable technique to carry out intelligent design, develop the equipment that can dress to daily wearing, like glasses, gloves, wrist-watch, dress and shoes etc.. A wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user.

The generalized wearable smart device includes full functionality, large size, and can implement full or partial functionality without relying on a smart phone, such as: smart watches or smart glasses and the like, and only focus on a certain type of application functions, and need to be used in cooperation with other devices such as smart phones, such as various smart bracelets, smart helmets, smart jewelry and the like for monitoring physical signs.

2) The network device includes, for example, AN Access Network (AN) device. An access network device, such as a base station (e.g., access point), may refer to a device in an access network that communicates over the air-interface, through one or more cells, with wireless terminal devices. The network device may be configured to interconvert received air frames and Internet Protocol (IP) packets as a router between the terminal device and the rest of the access network, which may include an IP network. The network device may also coordinate attribute management for the air interface. For example, the network device may include an evolved Node B (NodeB or eNB or e-NodeB) in a Long Term Evolution (LTE) system or an evolved LTE system (LTE-Advanced, LTE-a), or may also include a next generation Node B (gNB) in a fifth generation mobile communication technology (5G) New Radio (NR) system, or may also include a Centralized Unit (CU) and a Distributed Unit (DU) in a cloud access network (cloud ran) system, which is not limited in the embodiments of the present application.

5) The terms "system" and "network" in the embodiments of the present application may be used interchangeably. "plurality" means two or more, and in view of this, a plurality may also be understood as "at least two" in the embodiments of the present application. "at least one" is to be understood as meaning one or more, for example one, two or more. For example, the inclusion of at least one is intended to include one, two or more, and is not intended to be limiting, for example, to include at least one of A, B and C, and then includes a, B, C, a and B, a and C, B and C, or a and B and C. "at least two", is to be understood as two or more. Similarly, the understanding of the description of "at least one" and the like is similar. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, or B exists alone. In addition, the character "/" generally indicates that the preceding and following related objects are in an "or" relationship, unless otherwise specified.

And, unless stated to the contrary, the embodiments of the present application refer to the ordinal numbers "first", "second", etc., for distinguishing a plurality of objects, and do not limit the sequence, timing, priority, or importance of the plurality of objects. For example, the first logical channel and the second logical channel are only for distinguishing different logical channels, and do not indicate a difference in priority, importance, or the like between the two logical channels.

Having described some concepts related to embodiments of the present application, the following description will be given of features related to embodiments of the present application.

In a 5G system, a mechanism for repeatedly sending PDCP layer data is introduced, and the general idea is that if a repeated transmission function of the PDCP layer is configured and activated for a radio bearer, each original data packet generated by the PDCP layer needs to be copied into one same data packet, and then the original data packet and the copied data packet are delivered to two different RLC entities by the PDCP layer and transmitted to the MAC layer through different logical channels.

In order to ensure the reliability of data transmission, the original data packet and the copied data packet transmitted to the MAC layer cannot be transmitted through the same MAC PDU, because only through transmission of different MAC PDUs, the transmission of another MAC PDU cannot be affected if one MAC PDU is lost, which is equivalent to that the reliability is doubled.

In the following, how the transmission function of the PDCP layer is implemented is described separately for the DC scenario and the CA scenario.

Please refer to fig. 1, which is a network architecture involved in implementing the repeated transmission function of the PDCP layer in the DC scenario. For the base station, the DC scenario involves a main base station and a secondary base station, and the network architecture of the main base station and the secondary base station for one radio bearer is as shown in fig. 1, and the network architecture of the terminal device for the radio bearer includes the network architecture of the main base station and the network architecture of the secondary base station shown in fig. 1, that is, the terminal device includes one PDCP entity, two RLC entities and two MAC entities for the radio bearer. Security (security), replication (duplication), segmentation (segment), automatic repeat-request (ARQ), multiplexing (multiplexing), hybrid automatic repeat-request (HARQ), robust header compression (ROHC), and the like in fig. 1 are functions representing a PDCP entity, an RLC entity, or a MAC entity. Herein, the PDCP entity and the PDCP layer can be understood as the same concept, and similarly, the RLC entity and the RLC layer can be understood as the same concept, and the MAC entity and the MAC layer can be understood as the same concept.

In a DC scenario, a terminal device connects two base stations, that is, a primary base station and a secondary base station, and if a duplicate transmission function of a PDCP layer is configured for a certain radio bearer, two duplicated data packets in the PDCP layer are transmitted to two different RLC entities and transmitted to different MAC entities through different logical channels, so as to form two MAC PDUs for transmission on different carriers. The procedure is the same for both the base station and the terminal device, except that for the base station, the PDCP layer in the primary base station transmits the two duplicated data packets to two different RLC entities, which are respectively located in the primary base station and the secondary base station, and then the RCL entity in the primary base station transmits the received data packet to the MAC entity in the primary base station, and the RCL entity in the secondary base station transmits the received data packet to the MAC entity in the secondary base station, which transmit the data packets via respective carriers. And for the terminal device, two RCL entities and two MAC entities are located in the terminal device, and other processes are the same.

Please refer to fig. 2, which is a network architecture involved in implementing the repeated transmission function of the PDCP layer in the CA scenario. In the CA scenario, the terminal device is connected to a base station, and the network architecture of the base station and the terminal device for one radio bearer is as shown in fig. 2, that is, the base station and the terminal device for the radio bearer each include one PDCP entity, two RLC entities and two MAC entities. The security, copy, segmentation, ARQ, multiplexing, HARQ, and ROHC in fig. 2 all represent functions of a PDCP entity, an RLC entity, or a MAC entity.

In a CA scenario, a terminal device is connected to a base station, and the same base station has more than one carrier serving the terminal device. Assuming that a certain radio bearer is configured with the function of repeated transmission of the PDCP layer, two data packets duplicated in the PDCP layer are transmitted to two different RLC entities, and the two RLC entities transmit to the same MAC entity through different logical channels. At this time, since two data packets are transmitted to the same MAC entity, the MAC entity places the two data packets into one MAC PDU for transmission, so that in order to enable the two data packets to be transmitted through the two MAC PDUs respectively, a parameter, for example, referred to as parameter a, may be configured for the logical channel, and different carriers are indicated by a value of the parameter a, thereby ensuring that the two data packets can finally form two MAC PDUs for transmission on different carriers.

For example, if a parameter a is configured for a logical channel, it indicates that data in the RLC entity corresponding to the logical channel can only be transmitted on the carrier indicated by the parameter a. Therefore, if the parameter a configured for the two logical channels that are duplicated with each other indicates different carriers, two data packets that are duplicated with each other will be finally transmitted on the different carriers, so as to ensure reliability.

Therefore, the binding transmission relationship between the logical channel and the carrier wave, or referred to as the corresponding transmission relationship, can be ensured by setting the parameters. In the 5G system, the duplicate transmission function of the PDCP layer may be configured for the radio bearer, and the duplicate transmission function of the PDCP layer configured for the radio bearer may also be deactivated. When the repeated transmission of the PDCP layer configured for a radio bearer is deactivated, the corresponding transmission relationship between the logical channel and the carrier in the radio bearer is no longer applicable, which may cause certain problems, and for clarity of description, the following description is provided with reference to the accompanying drawings.

Please refer to fig. 3. For example, initially, a radio bearer does not configure the duplicate transmission function of the PDCP layer, but configures a parameter a for a logical channel included in the radio bearer, where the parameter a may indicate that data from a logical channel 1 (a logical channel of the RLC 1) can only be transmitted on carrier 1 or carrier 2, but cannot be transmitted on carrier 3. Then, configuring a retransmission function of the PDCP layer for the radio bearer, and configuring the logical channel 1 as a transmission path for performing retransmission when configuring the retransmission function of the PDCP layer for the radio bearer, where at this time, for example, a value of an original parameter a of the logical channel 1 is not changed, the parameter a of the logical channel 1 continues to indicate that data from the logical channel 1 can only be transmitted on the carrier 1 or the carrier 2, or, for example, a value of an original parameter a of the logical channel 1 is changed, so that the parameter a of the logical channel 1 indicates that data from the logical channel 1 can only be transmitted on the carrier 1. Logical channel 2 (the logical channel of RLC 2) is also configured with parameter a, which indicates that data from logical channel 2 can only be transmitted on carrier 3. At a later time, the duplicate transmission function of the PDCP layer of the radio bearer is deactivated, and then both the parameter a configured for logical channel 1 and the parameter a configured for logical channel 2 are deleted, that is, both the corresponding transmission relationship with the carrier configured for logical channel 1 and the corresponding transmission relationship with the carrier configured for logical channel 2 are not used.

It can be seen that, at present, no matter for the repeat transmission function of the PDCP layer or for the repeat function of the non-PDCP layer, the same parameter configuration is used when configuring a carrier corresponding to a logical channel (that is, configuring a carrier for the logical channel, or configuring a corresponding transmission relationship between the logical channel and the carrier), and thus it cannot be distinguished, and it is possible that a parameter a configured for the logical channel 1 is not configured for a repeat transmission scenario of the PDCP layer, but after the repeat transmission function of the PDCP layer of the radio bearer is deactivated, the parameter a configured for the logical channel 1 is also deleted, so that subsequent other scenarios cannot continue to apply the corresponding transmission relationship between the logical channel 1 and the carriers 1 and 2. Or, the parameter a initially configured for the logical channel 1 is not configured for the retransmission scenario of the PDCP layer, but when the retransmission scenario of the PDCP layer is activated, the value of the parameter a of the logical channel 1 may be changed, which is equivalent to covering the original configuration, and after the retransmission function of the PDCP layer of the radio bearer is deactivated, the original configuration of the logical channel 1 does not exist any more.

In view of this, the technical solutions of the embodiments of the present application are provided. In this embodiment of the present application, two different parameters, that is, a first parameter and a second parameter, may be configured for the retransmission function of the PDCP layer and the retransmission function of the non-PDCP layer, so that after the retransmission function of the PDCP layer is deactivated, only the first parameter corresponding to the retransmission function of the PDCP layer may be deleted, and the second parameter configured for the retransmission function of the non-PDCP layer may be continuously reserved, that is, the corresponding transmission relationship between the logical channel and the carrier determined according to the second parameter may continue to exist, so that after the retransmission function of the PDCP layer is deactivated, the corresponding transmission relationship between the logical channel and the carrier configured for the retransmission function of the non-PDCP layer may continue to be applied. Herein, the duplicate transmission function of the non-PDCP layer generally refers to functions other than the duplicate transmission function of the PDCP layer, for example, includes the functions of the PDCP layer, or includes the functions of other layers, and is not to be construed as including only the duplicate transmission function of the layers other than the PDCP layer.

The technical solution provided in the embodiment of the present application may be applied to a 5G NR system, or may be applied to an LTE system, or may be applied to a next generation mobile communication system or other similar communication systems, which is not limited specifically. In addition, the technical scheme provided by the embodiment of the application can be applied to a CA scene, a DC scene or other scenes.

Fig. 4 includes a network device and a terminal device, and the terminal device is connected to one network device. Of course, the number of the terminal devices in fig. 4 is only an example, in practical application, the network device may provide services for a plurality of terminal devices, and all or part of the terminal devices in the plurality of terminal devices may send the capability information to the network device by using the method provided in the embodiment of the present application.

Referring to fig. 5, in another application scenario of the embodiment of the present application, the scenario shown in fig. 5 may be understood as a DC scenario. Fig. 5 includes two network devices and a terminal device, where the two network devices are a first network device and a second network device respectively, the first network device is, for example, 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. Both network devices are, for example, base stations, and the primary network device is the primary base station and the secondary network device is the secondary base station. Wherein the first network device operates in an evolved universal mobile telecommunications system terrestrial radio access (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, and the second network device operates in an E-UTRA system, for example, or both the first network device and the second network device operate in an NR system or an E-UTRA system, for example. Wherein the terminal device is connected to both network devices simultaneously, and the terminal device can communicate with both network devices.

The network device in fig. 4 or fig. 5 is, for example, a base station. The network device corresponds to different devices in different systems, for example, the network device may correspond to an eNB in a fourth generation mobile communication technology (4G) system, and the network device in a 5G, for example, a gNB, in a fifth generation mobile communication technology (5G) system.

The technical scheme provided by the embodiment of the application is described below with reference to the accompanying drawings. Also hereinafter, the duplicate transmission function of the PDCP layer is simply referred to as a duplicate transmission function, and the duplicate transmission function of the non-PDCP layer is simply referred to as a non-duplicate transmission function. The non-duplicate transmission function may generally refer to other functions besides the duplicate transmission function, for example, a function for a Licensed Assisted Access (LAA) scenario, a function for meeting a requirement of a Maximum Data Burst Volume (MDBV), or the like.

A first embodiment of the present application provides a method for configuring a carrier, please refer to fig. 6, which is a flowchart of the method. The method may be applied to the scenario shown in fig. 4 or the scenario shown in fig. 5, wherein if the method is applied to the scenario shown in fig. 5, the network device involved in the method may be the first network device or the second network device in the scenario shown in fig. 5. In addition, the method may be performed by two communication apparatuses, for example, a first communication apparatus and a second communication apparatus, where the first communication apparatus may be a network device or a communication apparatus capable of supporting the network device to implement the functions required by the method, or the first communication apparatus may be a terminal device or a communication apparatus capable of supporting the terminal device to implement the functions required by the method, and may of course be other communication apparatuses such as a system on chip. The same applies to the second communication apparatus, which may be a network device or a communication apparatus capable of supporting the network device to implement the functions required by the method, or a terminal device or a communication apparatus capable of supporting the terminal device to implement the functions required by the method, and of course, other communication apparatuses such as a system on a chip may also be used. The implementation manners of the first communication apparatus and the second communication apparatus are not limited, for example, the first communication apparatus may be a network device, the second communication apparatus is a terminal device, or both the first communication apparatus and the second communication apparatus are network devices, or both the first communication apparatus and the second communication apparatus are terminal devices, or the first communication apparatus is a network device, and the second communication apparatus is a communication apparatus capable of supporting the terminal device to implement the functions required by the method, and so on. The network device is, for example, a base station.

For convenience of introduction, in the following, the method is taken as an example executed by a network device and a terminal device, that is, the first communication apparatus is taken as a network device, and the second communication apparatus is taken as a terminal device.

S61, the network device determines a first parameter of a first logical channel, where the first parameter is used to indicate that a carrier used for transmitting data in the first logical channel is a first carrier, the first logical channel belongs to a first radio bearer, the first radio bearer is configured with a repeat transmission function, and the repeat transmission function is activated, and the first parameter is different from a second parameter, the second parameter is used to indicate that a carrier used for transmitting data in the second logical channel is a second carrier, the second logical channel belongs to a second radio bearer, the second radio bearer is not configured with a repeat transmission function, or the second radio bearer is configured with the repeat transmission function, but the repeat transmission function is not activated;

s62, the network device sends a first message, and the terminal device receives the first message from the network device, wherein the first message comprises the first parameter;

and S63, the terminal equipment determines to transmit the data in the first logical channel only by using the first carrier according to the first parameter.

The number of the first logical channels is not limited in the embodiments of the present application, and the first logical channels may be one or more, for example, the first logical channel may be one logical channel belonging to the first radio bearer, or may also be multiple logical channels belonging to the first radio bearer. Likewise, the number of the second logical channels is not limited, and the second logical channels may be one or more, for example, the second logical channel may be one logical channel belonging to the second radio bearer, or may also be multiple logical channels belonging to the second radio bearer. In addition, the number of the first carriers is not limited, and the number of the first carriers may be one or more, and the same applies to the second carriers, and the number may be one or more.

In the embodiment of the present application, the first logical channel and the second logical channel may be the same logical channel, or may also be different logical channels. In addition, if the first logical channel and the second logical channel are the same logical channel, the first radio bearer and the second radio bearer may be the same radio bearer, and the first radio bearer is configured with the duplicate transmission function and the duplicate transmission function is activated, the second radio bearer is not configured with the duplicate transmission function, or the second radio bearer is configured with the duplicate transmission function but the duplicate transmission function is not activated, it is understood that the parameter configured for the first logical channel (or the second logical channel) for indicating the carrier is the first parameter when the first radio bearer (or the second radio bearer) is configured with the duplicate transmission function and the duplicate transmission function is activated, and the first radio bearer (or the second radio bearer) is not configured with the duplicate transmission function or when the duplicate transmission function is configured but the duplicate transmission function is not activated, the parameter configured for the first logical channel (or the second logical channel) to indicate the carrier is a second parameter. That is, since the radio bearer to which a logical channel belongs may be configured with different functions, a plurality of different parameters may be configured for a logical channel, and the configuration of two parameters is taken as an example here.

And if the first logical channel and the second logical channel are different logical channels, the first radio bearer and the second radio bearer may be the same radio bearer or may be different radio bearers. If the first logical channel and the second logical channel are different logical channels and the first radio bearer and the second radio bearer are the same radio bearer, it can be understood that the first radio bearer (or the second radio bearer) configures a first parameter for indicating a carrier for the first logical channel when the duplicate transmission function is configured and activated, and the first radio bearer (or the second radio bearer) configures a second parameter for indicating a carrier for the second logical channel when the duplicate transmission function is not configured or when the duplicate transmission function is configured and not activated. Or, if the first logical channel and the second logical channel are different logical channels and the first radio bearer and the second radio bearer are different radio bearers, it can be understood that the first radio bearer configures a first parameter for indicating a carrier for the first logical channel if the duplicate transmission function is configured and activated, and the second radio bearer configures a second parameter for indicating a carrier for the second logical channel if the duplicate transmission function is not configured or the duplicate transmission function is configured but not activated.

For the first radio bearer in which the duplicate transmission function is configured and the duplicate transmission function is activated, if the network device is to configure a corresponding carrier for the first logical channel belonging to the first radio bearer, the first logical channel may be configured with a first parameter, for example, the network device may send a first message to the terminal device, and the terminal device may receive the first message from the network device, where the first message includes the first parameter. The first message may be, for example, a Radio Resource Control (RRC) message, or may be another message. The first parameter may be configured to the first logical channel and used to indicate that a carrier used for transmitting data in the first logical channel is the first carrier, and it may also be understood that the first parameter indicates a corresponding transmission relationship, that is, a corresponding transmission relationship between the first logical channel and the first carrier. In the various embodiments herein, the correspondence relation is also simply referred to as correspondence relation for brevity. After the terminal device obtains the first parameter, it may determine to transmit the data in the first logical channel by using the first carrier according to the first parameter. The first parameter may indicate that the carrier used for transmitting the data in the first logical channel is only the first carrier, and then the terminal device may determine, according to the first parameter, that the data in the first logical channel is transmitted only by using the first carrier. Here, "only" may be understood as that data in the first logical channel is transmitted only according to the first carrier indicated by the first parameter, and data in the first logical channel is transmitted without carriers not indicated by the first parameter.

In a possible implementation manner, the network device may further configure a corresponding carrier for a second logical channel belonging to a second radio bearer, for example, the second radio bearer is not configured with a duplicate transmission function, or the second radio bearer is configured with a duplicate transmission function, but the duplicate transmission function is not activated, the network device may determine a second parameter of the second logical channel, that is, configure the second parameter for the second logical channel, the network device may send a second message, the terminal device may receive a second message from the network device, and the second message may include the second parameter, so that the terminal device may obtain the second parameter to determine to transmit data in the second logical channel with the second carrier according to the second parameter. The second message is, for example, an RRC message, or may be another message. The second parameter may indicate that the carrier used for transmitting the data in the second logical channel is only the second carrier, and then the terminal device may determine, according to the second parameter, that the data in the second logical channel is transmitted only by using the second carrier. Here, "only" may be understood to mean that data in the second logical channel is transmitted only according to the second carrier indicated by the second parameter, and data in the second logical channel is transmitted without carriers not indicated by the second parameter.

The first message and the second message may be different messages, for example, the first message is an RRC message, and the second message is another RRC message, or the first message and the second message may be the same message, for example, both of them are the same RRC message, and then the first parameter and the second parameter are included in the RRC message.

In the embodiment of the present application, corresponding parameters are set for the retransmission function and the non-retransmission function, that is, when corresponding carriers are set for a logical channel of a radio bearer in which the retransmission function is configured and activated, a first parameter is used, and when corresponding carriers are set for a logical channel of a radio bearer in which the retransmission function is not configured or the retransmission function is configured and the retransmission function is not activated, a second parameter is used, where the first parameter and the second parameter are different parameters. Then, after the repeated transmission function of the first radio bearer is deactivated, since the first parameter and the second parameter are different parameters, the second parameter may continue to exist, that is, both the network device and the terminal device may continue to transmit data in the second logical channel only by using the second carrier according to the indication of the second parameter. By adopting the technical scheme of the embodiment of the application, both the network device and the terminal device can clearly know that the second parameter set for the non-repetitive transmission function is still applicable after the repetitive transmission function of one radio bearer is deactivated, namely, the corresponding relation between the logical channel set for the non-repetitive transmission function and the carrier wave is still applicable, so that the corresponding relations do not need to be reset.

In addition, the embodiment of the present application provides that, after the repeated transmission function of the first radio bearer is deactivated, even for the first parameter, the first parameter may be selected to be deleted, or the network device and the terminal device may continue to store the first parameter, that is, after the repeated transmission function of the first radio bearer is deactivated, the network device and the terminal device may continue to transmit data of the first logical channel only in the first carrier according to an indication of the first parameter. It can be seen that even for the first parameter set for the repeat transmission function, the continuous use can be selected after the repeat transmission function is deactivated, so that the application range of the first parameter is wider.

For example, the first logical channel and the second logical channel are the same logical channel, the first radio bearer and the second radio bearer are the same radio bearer, the parameter configured for the first logical channel (or the second logical channel) to indicate the carrier is the first parameter when the duplicate transmission function is configured and activated, and the parameter configured for the first logical channel (or the second logical channel) to indicate the carrier is the second parameter when the duplicate transmission function is not configured or when the duplicate transmission function is configured and not activated. Once the first radio bearer (or the second radio bearer) is deactivated, only the first parameters configured for the first logical channel (or the second logical channel) may be deleted, while the second parameters configured for the first logical channel (or the second logical channel) may not be deleted, and of course, the first parameters may also be selected to be deleted or continuously stored. Moreover, since the first parameter and the second parameter are different parameters, even if the first parameter is configured after the second parameter is configured for the first logical channel (or the second logical channel), the first parameter does not cover the second parameter, so that the second parameter can continuously exist, even if the first radio bearer (or the second radio bearer) is deactivated, the second parameter can be continuously stored, so that the data in the first logical channel (or the second logical channel) can be continuously transmitted by using the second carrier according to the second parameter, and it can be understood that the corresponding relationship between the first logical channel (or the second logical channel) and the second carrier, which is indicated by the second parameter, still exists, so that even if the first radio bearer (or the second radio bearer) is deactivated, the second parameter is not affected, for example, when a non-repeat transmission function is subsequently implemented through the first radio bearer (or the second radio bearer), the second parameter may also continue to be applied.

In the embodiment shown in fig. 6, the technical problem is solved by configuring two parameters. In order to solve the same problem, a second method for configuring a carrier is provided below, in which only one parameter needs to be configured, which is more compatible with the prior art and can also solve the technical problem.

Fig. 7 is a flowchart of the method. The method may be applied to the scenario shown in fig. 4 or the scenario shown in fig. 5, wherein if the method is applied to the scenario shown in fig. 5, the network device involved in the method may be the first network device or the second network device in the scenario shown in fig. 5. In addition, the method may be performed by two communication apparatuses, for example, a first communication apparatus and a second communication apparatus, where the first communication apparatus may be a network device or a communication apparatus capable of supporting the network device to implement the functions required by the method, or the first communication apparatus may be a terminal device or a communication apparatus capable of supporting the terminal device to implement the functions required by the method, and may of course be other communication apparatuses such as a system on chip. The same applies to the second communication apparatus, which may be a network device or a communication apparatus capable of supporting the network device to implement the functions required by the method, or a terminal device or a communication apparatus capable of supporting the terminal device to implement the functions required by the method, and of course, other communication apparatuses such as a system on a chip may also be used. The implementation manners of the first communication device and the second communication device are not limited, for example, the first communication device may be a network device, the second communication device is a terminal device, or both the first communication device and the second communication device are network devices, or both the first communication device and the second communication device are terminal devices, or the first communication device is a network device, and the second communication device is a communication device capable of supporting the terminal device to implement the functions required by the method, and so on. The network device is, for example, a base station.

For convenience of introduction, in the following, the method is performed by a network device and a terminal device as an example, that is, the first communication apparatus is a network device and the second communication apparatus is a terminal device as an example.

S71, a network device determines a first value of a parameter of a first logical channel, where the first value is used to indicate that a carrier used for transmitting data in the first logical channel is a first carrier, the first logical channel belongs to a first radio bearer, the first radio bearer is configured with a repeat transmission function, and the repeat transmission function is activated, the first value and a second value of the parameter are determined according to different value rules, the second value is used to indicate that a carrier used for transmitting data in a second logical channel is a second carrier, the second logical channel belongs to a second radio bearer, the second radio bearer is not configured with a repeat transmission function, or the second radio bearer is configured with the repeat transmission function, but the repeat transmission function is not activated;

s72, the network equipment sends a first message, and the terminal equipment receives the first message from the network equipment, wherein the first message comprises a first value of the parameter;

and S73, the terminal equipment determines to transmit the data in the first logic channel only by using the first carrier according to the first value of the parameter.

The number of the first logical channels is not limited in the embodiments of the present application, and the first logical channels may be one or more, for example, the first logical channel may be one logical channel belonging to the first radio bearer, or may also be multiple logical channels belonging to the first radio bearer. Likewise, the number of the second logical channels is not limited, and the second logical channels may be one or more, for example, the second logical channel may be one logical channel belonging to the second radio bearer, or may also be multiple logical channels belonging to the second radio bearer. In addition, the number of the first carriers is not limited, the number of the first carriers may be one or more, the number of the second carriers may be the same, and the number of the second carriers may be one or more.

In the embodiment of the present application, the first logical channel and the second logical channel may be the same logical channel, or may also be different logical channels. In addition, if the first logical channel and the second logical channel are the same logical channel, the first radio bearer and the second radio bearer may be the same radio bearer, and the first radio bearer is configured with the duplicate transmission function and the duplicate transmission function is activated, the second radio bearer is not configured with the duplicate transmission function, or the second radio bearer is configured with the duplicate transmission function but the duplicate transmission function is not activated, it is understood that, in the case that the first radio bearer (or the second radio bearer) is configured with the duplicate transmission function and the duplicate transmission function is activated, the value of the parameter configured for the first logical channel (or the second logical channel) and used for indicating the carrier is the first value, and in the case that the first radio bearer (or the second radio bearer) is not configured with the duplicate transmission function or is configured with the duplicate transmission function but the duplicate transmission function is not activated, the value of the parameter configured for the first logical channel (or the second logical channel) and used for indicating the carrier is the second value, that is, in view of that the radio bearer to which one logical channel belongs may be configured with different functions, different values of one parameter may be configured for one logical channel, and here, the configuration of the two values is taken as an example.

In this embodiment of the present application, the first value and the second value of the parameter may be determined according to different value rules, for example, the first value of the parameter corresponds to the first value rule, and the second value of the parameter corresponds to the second value rule, or in other words, the first value of the parameter is determined according to the first value rule, and the second value of the parameter is determined according to the second value rule. The first value rule may be applicable to a scenario in which the retransmission function is activated, and the second value rule may be applicable to a scenario in which the retransmission function is not activated or configured. Alternatively, the first value and the second value of the parameter are determined according to different value rules, which may also be understood as that the first value and the second value of the parameter are applicable in different scenarios, for example, the first value is applicable to a scenario in which the retransmission function is activated, and the second value is applicable to a scenario in which the retransmission function is not activated or configured.

For example, for the parameter a, a plurality of different value rules may be corresponded, and here, two different value rules are taken as an example, for example, when corresponding to the first value rule, the value of the parameter a may be 1,2,3, … …, and when corresponding to the first value rule, the value of the parameter a may be a, b, c, … …, then, the first value is, for example, 1, and the second value is, for example, a. Different value rules may correspond to different functions, for example, a first value rule of the parameter may correspond to a repetitive transmission function, and a second value rule may correspond to a non-repetitive transmission function.

And if the first logical channel and the second logical channel are different logical channels, the first radio bearer and the second radio bearer may be the same radio bearer or may be different radio bearers. If the first logical channel and the second logical channel are different logical channels and the first radio bearer and the second radio bearer are the same radio bearer, it can be understood that, when the first radio bearer (or the second radio bearer) configures a duplicate transmission function and the duplicate transmission function is activated, a first value of the parameter is configured for the first logical channel to indicate a carrier, and when the first radio bearer (or the second radio bearer) does not configure the duplicate transmission function or when the duplicate transmission function is configured but the duplicate transmission function is not activated, a second value of the parameter is configured for the second logical channel to indicate a carrier. Or, if the first logical channel and the second logical channel are different logical channels and the first radio bearer and the second radio bearer are different radio bearers, it can be understood that, in the case that the first radio bearer configures a duplicate transmission function and the duplicate transmission function is activated, a first value of the parameter is configured for the first logical channel to indicate a carrier, and in the case that the second radio bearer does not configure the duplicate transmission function or in the case that the duplicate transmission function is configured but the duplicate transmission function is not activated, a second value of the parameter is configured for the second logical channel to indicate a carrier.

For a first radio bearer in which a duplicate transmission function is configured and the duplicate transmission function is activated, if a network device is to configure a corresponding carrier for a first logical channel belonging to the first radio bearer, the first logical channel may be configured according to a first value-taking rule of the parameter, for example, according to the first value-taking rule, a first value of the parameter is configured for the first logical channel, the parameter may be configured for the first logical channel, and the first value is used to indicate that a carrier used for transmitting data in the first logical channel is the first carrier, or may be understood as that the parameter indicates a corresponding relationship, for example, the first value indicates a corresponding relationship between the first logical channel and the first carrier. For example, the network device may send the first message to the terminal device, and then the terminal device may receive the first message from the network device, where the first message includes the first value. The first message is, for example, an RRC message, or may be another message. After the terminal device obtains the first value of the parameter, it can determine to transmit the data in the first logical channel by using the first carrier according to the first value. The first value may indicate that the carrier used for transmitting the data in the first logical channel is only the first carrier, and then the terminal device may determine, according to the first value, to transmit the data in the first logical channel only by using the first carrier. Here, "only" may be understood to mean that data in the first logical channel is transmitted only according to the first carrier indicated by the first value, and data in the first logical channel is transmitted without the carrier not indicated by the first value.

In a possible implementation manner, the network device may further configure a corresponding carrier for a second logical channel belonging to a second radio bearer, for example, the second radio bearer is not configured with a repeat transmission function, or the second radio bearer is configured with a repeat transmission function, but the repeat transmission function is not activated, the network device may determine a value of the parameter of the second logical channel, that is, configure the value of the parameter for the second logical channel, and the network device may be configured according to a second value rule of the parameter, for example, configure the second logical channel with a second value of the parameter according to the second value rule. In addition, the network device may further send a second message, and the terminal device may receive the second message from the network device, where the second message may include a second value, so that the terminal device may obtain the second value, and determine to transmit data in the second logical channel by using the second carrier according to the second value. The second message is, for example, an RRC message, or may be another message. The second value may indicate that the carrier used for transmitting the data in the second logical channel is only the second carrier, and the terminal device may determine, according to the second value, that the data in the second logical channel is transmitted only by using the second carrier. Here, "only" may be understood to mean that the data in the second logical channel is transmitted only according to the second carrier indicated by the second value, and the data in the second logical channel is transmitted without using the carrier not indicated by the second value.

The first message and the second message may be different messages, for example, the first message is an RRC message, and the second message is another RRC message, or the first message and the second message may be the same message, for example, the first message and the second message are the same RRC message, and the RRC message includes the first value and the second value.

In this embodiment, values are set for the retransmission function and the non-retransmission function according to different value rules of the parameter, that is, when corresponding carriers are set for a logical channel of a radio bearer configured with the retransmission function and activated with the retransmission function, values (for example, a first value) determined according to a first value rule of the parameter are used, and when corresponding carriers are set for a logical channel of a radio bearer not configured with the retransmission function or configured with the retransmission function but not activated with the retransmission function, values (for example, a second value) determined according to a second value rule of the parameter are used. Then, after the repeated transmission function of the first radio bearer is deactivated, since the first value and the second value are determined according to different value rules, the second value may continue to exist, that is, both the network device and the terminal device may continue to transmit data in the second logical channel only by using the second carrier according to the indication of the second value. By adopting the technical scheme of the embodiment of the application, both the network device and the terminal device can clearly know that the second value set for the non-repetitive transmission function is still applicable after the repetitive transmission function of one radio bearer is deactivated, that is, the corresponding relation between the logical channel set for the non-repetitive transmission function and the carrier wave is still applicable, so that the corresponding relations do not need to be reset. In addition, only one parameter still needs to be set in the embodiment of the application, and excessive parameters do not need to be set, so that the method and the device are compatible with the prior art.

In addition, in the embodiment of the present application, after the repeated transmission function of the first radio bearer is deactivated, even if the first value of the parameter is determined to be deleted, or the network device and the terminal device may continue to store the first value, that is, after the repeated transmission function of the first radio bearer is deactivated, the network device and the terminal device may continue to transmit the data of the first logical channel only in the first carrier according to the indication of the first value. Therefore, even for the first value set for the repeated transmission function, the first value can be selected to be continuously used after the repeated transmission function is deactivated, so that the application range of the first value is wider.

For example, the first logical channel and the second logical channel are the same logical channel, the first radio bearer and the second radio bearer are the same radio bearer, when the first radio bearer (or the second radio bearer) is configured with the duplicate transmission function and the duplicate transmission function is activated, the value of the parameter configured for the first logical channel (or the second logical channel) and used for indicating the carrier is a first value, and when the first radio bearer (or the second radio bearer) is not configured with the duplicate transmission function or when the duplicate transmission function is configured but not activated, the value of the parameter configured for the first logical channel (or the second logical channel) and used for indicating the carrier is a second value. Once the first radio bearer (or the second radio bearer) is deactivated, only the first value configured for the first logical channel (or the second logical channel) may be deleted, while the second value configured for the first logical channel (or the second logical channel) may not be deleted, and of course, the first value may also be deleted or stored continuously. Moreover, since the first value and the second value are determined according to different value rules, even if the first value is configured after the second value is configured for the first logical channel (or the second logical channel), the first value does not cover the second value, so that the second value can continuously exist, even if the first radio bearer (or the second radio bearer) is deactivated, the second value can be continuously stored, so that it can be continuously determined according to the second value that the data in the first logical channel (or the second logical channel) is transmitted by using the second carrier, it can also be understood that the corresponding relationship between the first logical channel (or the second logical channel) and the second carrier indicated by the second value still exists, so that even if the first radio bearer (or the second radio bearer) is deactivated, the second value is not affected, for example, when a non-repeat transmission function is subsequently realized through the first radio bearer (or the second radio bearer), the second value may also continue to be applied.

In both the embodiment shown in fig. 6 and the embodiment shown in fig. 7, the technical problem is solved by setting parameters, and other embodiments are provided below for solving the technical problem by other means.

A third method for configuring a carrier is provided in the present embodiment, please refer to fig. 8, which is a flowchart of the method. The method may be applied to the scenario shown in fig. 4 or the scenario shown in fig. 5, wherein if the method is applied to the scenario shown in fig. 5, the network device involved in the method may be the first network device or the second network device in the scenario shown in fig. 5. In addition, the method may be performed by two communication apparatuses, for example, a first communication apparatus and a second communication apparatus, where the first communication apparatus may be a network device or a communication apparatus capable of supporting the network device to implement the functions required by the method, or the first communication apparatus may be a terminal device or a communication apparatus capable of supporting the terminal device to implement the functions required by the method, and may of course be other communication apparatuses such as a system on chip. The same applies to the second communication apparatus, which may be a network device or a communication apparatus capable of supporting the network device to implement the functions required by the method, or a terminal device or a communication apparatus capable of supporting the terminal device to implement the functions required by the method, and of course, other communication apparatuses such as a system on a chip may also be used. The implementation manners of the first communication device and the second communication device are not limited, for example, the first communication device may be a network device, the second communication device is a terminal device, or both the first communication device and the second communication device are network devices, or both the first communication device and the second communication device are terminal devices, or the first communication device is a network device, and the second communication device is a communication device capable of supporting the terminal device to implement the functions required by the method, and so on. The network device is, for example, a base station.

S81, the network device determines indication information, where the indication information is used to indicate whether the terminal device continues to transmit data in a first logical channel only by using a first carrier after the repeated transmission function of a first radio bearer is deactivated, where the first logical channel belongs to the first radio bearer;

s82, the network equipment sends the indication information, and the terminal equipment receives the indication information from the network equipment;

s83, the terminal device determines, according to the indication information, whether to continue to transmit data in the first logical channel only by using the first carrier after the repeated transmission function of the first radio bearer is deactivated, where the first logical channel belongs to the first radio bearer.

In fact, the terminal device responds to the indication information, so that after the repeated transmission function of the first radio bearer is deactivated, the data in the first logical channel continues to be transmitted by using only the first carrier, or after the repeated transmission function of the first radio bearer is deactivated, the carrier used for transmitting the data in the first logical channel is not limited. The data in the first logical channel is transmitted only with the first carrier, which is understood to be configured by a parameter, which may be configured to the logical channel. For example, the parameter is configured for a repeat transmission function, or the parameter may be configured for a non-repeat transmission function, that is, there is no limitation on why the parameter is configured. Therefore, no matter the corresponding relation between the logical channel configured for the repeat transmission function and the carrier, or the corresponding relation between the logical channel configured for other functions and the carrier, the network device can indicate whether to continue to use after the repeat transmission function of the first radio bearer is deactivated, which is flexible and expands the application range of the corresponding relations.

The parameter is configured for the retransmission function, and it can also be understood that the transmission of the data in the first logical channel using only the first carrier is configured when the retransmission function of the first radio bearer is activated, or that the transmission of the data in the first logical channel using only the first carrier is configured for the retransmission function of the first radio bearer. The parameter is configured for a non-duplicate transmission function, and it can also be understood that, when the duplicate transmission function of the first radio bearer is not activated or when the duplicate transmission function of the first radio bearer is not configured, the parameter is configured for transmitting data in the first logical channel only by using the first carrier, and is not configured for the duplicate transmission function of the first radio bearer.

The network device sends the first indication information, and in one mode, the network device sends a first message, where the first message includes the indication information. The first message may be used to configure a duplicate transmission function of the first radio bearer, that is, the first message is a message used to configure a duplicate transmission function for the first radio bearer, for example, an RRC message used to configure a duplicate transmission function for the first radio bearer; alternatively, the first message may be used to deactivate a duplicate transmission function of the first radio bearer, that is, the first message is a message for configuring the first radio bearer to deactivate the transmission function, for example, an RRC message or a medium access control element (MAC CE) for deactivating the duplicate transmission function of the first radio bearer.

It can be seen that the network device may determine whether the data in the first logical channel is transmitted by using only the first carrier, that is, whether the correspondence between the first carrier and the first logical channel can be used continuously after the repeated transmission function of the first radio bearer is deactivated, and indicate the information to the terminal device, so that the terminal device may determine whether to continue transmitting the data in the first logical channel by using only the first carrier after the repeated transmission function of the first radio bearer is deactivated. The network device may send the indication information to the terminal device when the duplicate transmission function is configured for the first radio bearer, or may send the indication information to the terminal device when the duplicate transmission function is deactivated for the first radio bearer, which is more flexible.

In the embodiment of the present application, the indication information may have different implementations, for example, an explicit implementation and an implicit implementation, which are separately described below.

1. Explicit implementation.

The network device directly carries the indication information in the first message, and the first message may be used to configure the duplicate transmission function of the first radio bearer, or the first message may be used to deactivate the duplicate transmission function of the first radio bearer.

In the first message, the indication information may occupy, for example, 1 or more bits, and the network device indicates, through the 1 or more bits, whether to continue to transmit the data in the first logical channel using only the first carrier after the repeated transmission function of the first radio bearer is deactivated. For example, the indication information occupies 1 bit, if the value of the 1 bit is "0", it indicates that the carrier used for transmitting the data in the first logical channel is not limited after the repeated transmission function of the first radio bearer is deactivated, and if the value of the 1 bit is "1", it indicates that the data in the first logical channel is continuously transmitted only by using the first carrier after the repeated transmission function of the first radio bearer is deactivated. For example, the first message may include one or more indication information, where each indication information may be used to indicate whether the corresponding relationship between the logical channel and the carrier is to be used after the repeated transmission function of the first radio bearer is deactivated.

After the repeated transmission function of the first radio bearer is deactivated, the carrier used for transmitting the data in the first logical channel is not limited, and it may be understood that the data in the first logical channel is transmitted by using the first carrier or another carrier after the repeated transmission function of the first radio bearer is deactivated. That is, after the repeated transmission function of the first radio bearer is deactivated, the correspondence between the first logical channel and the first carrier is released, and then the carriers used for transmitting the data in the first logical channel are not limited, specifically, which carrier or carriers are used to transmit the data in the first logical channel, as the case may be.

In an explicit implementation, the indication information is directly carried by the first message, so that the indication is more explicit.

2. Implicit implementation.

For example, the network device sends a first message, where the first message may be used to configure a retransmission function of the first radio bearer, or the first message may be used to deactivate the retransmission function of the first radio bearer, and at this time, the first message only needs to be the same as a message in the prior art, and does not need to carry additional indication information, and the first message itself may be used as the indication information.

For example, the first message is used to deactivate the duplicate transmission function of the first radio bearer, and in general, the duplicate transmission function of the first radio bearer may be deactivated through an RRC message or a MAC CE, and then the implicit indication may be performed through the two messages. For example, the protocol or the network device may provide in advance that, if the first message is an RRC message, the RRC message is used to instruct to deactivate the duplicate transmission function of the first radio bearer and to instruct to transmit data in the first logical channel only with the first carrier after the duplicate transmission function of the first radio bearer is deactivated, or, if the first message is a MAC CE, the MAC CE is used to instruct to deactivate the duplicate transmission function of the first radio bearer and to instruct to transmit data in the first logical channel with the first carrier or another carrier after the duplicate transmission function of the first radio bearer is deactivated; or the protocol or the network device may specify in advance that, if the first message is an RRC message, the RRC message is used to instruct to deactivate the duplicate transmission function of the first radio bearer, and to instruct to transmit the data in the first logical channel with the first carrier or the other carriers after the duplicate transmission function of the first radio bearer is deactivated, or, if the first message is a MAC CE, the MAC CE is used to instruct to deactivate the duplicate transmission function of the first radio bearer, and to instruct to transmit the data in the first logical channel with only the first carrier after the duplicate transmission function of the first radio bearer is deactivated. In this case, after the repeated transmission function of the first radio bearer is deactivated, the data in the first logical channel is transmitted by using the first carrier or another carrier, as described in the foregoing, it can also be understood that, after the repeated transmission function of the first radio bearer is deactivated, the carrier used for transmitting the data in the first logical channel is not limited.

Of course, here, only the RRC message and the MAC CE are taken as examples, and if the duplicate transmission function of the first radio bearer can also be deactivated through other messages, or the duplicate transmission function can also be configured for the first radio bearer through other messages, the implicit implementation manner is not limited to be implemented through other messages.

The indication is carried out through an implicit implementation mode, the network equipment only needs to send corresponding messages according to the prior art, and the messages do not need to carry contents such as extra indication information, and the transmission resources are saved.

In the embodiment of the present application, the network device may directly indicate the correspondence between the logical channel and the carrier through the indication information, and the implementation manner is relatively clear.

A fourth method for configuring a carrier is provided in the present embodiment, please refer to fig. 9, which is a flowchart of the method. The method may be applied to the scenario shown in fig. 4 or the scenario shown in fig. 5, wherein if the method is applied to the scenario shown in fig. 5, the network device involved in the method may be the first network device or the second network device in the scenario shown in fig. 5. In addition, the method may be performed by two communication apparatuses, for example, a first communication apparatus and a second communication apparatus, where the first communication apparatus may be a network device or a communication apparatus capable of supporting the network device to implement the functions required by the method, or the first communication apparatus may be a terminal device or a communication apparatus capable of supporting the terminal device to implement the functions required by the method, and may of course be other communication apparatuses such as a system on chip. The same applies to the second communication apparatus, which may be a network device or a communication apparatus capable of supporting the network device to implement the functions required by the method, or a terminal device or a communication apparatus capable of supporting the terminal device to implement the functions required by the method, and of course, other communication apparatuses such as a system on a chip may also be used. The implementation manners of the first communication device and the second communication device are not limited, for example, the first communication device may be a network device, the second communication device is a terminal device, or both the first communication device and the second communication device are network devices, or both the first communication device and the second communication device are terminal devices, or the first communication device is a network device, and the second communication device is a communication device capable of supporting the terminal device to implement the functions required by the method, and so on. The network device is, for example, a base station.

S91, the network equipment sends a deactivation message to the terminal equipment, and the terminal equipment receives the deactivation message from the network equipment, wherein the deactivation message is used for indicating the deactivation of the repeated transmission function of the first radio bearer;

s92, the terminal device determines whether a parameter indicating that data in a first logical channel is transmitted only by using a first carrier is configured for a repeat transmission function of the first radio bearer, where the first logical channel belongs to the first radio bearer;

s93, if the parameter is not configured for the repeated transmission function of the first radio bearer, the terminal device and the network device only use the first carrier to transmit the data in the first logical channel.

If the network device wants to deactivate the repeated transmission function of the first radio bearer, it may send a deactivation message to the terminal device, and after receiving the deactivation message, the terminal device may determine whether the correspondence between the logical channel and the carrier is configured for the repeated transmission function of the first radio bearer. Here, since the network device indicates that the duplicate transmission function of the first radio bearer is deactivated, what the terminal device judges may be a logical channel belonging to the first radio bearer. For example, there are 3 logical channels belonging to the first radio bearer, and 2 of the logical channels are configured with the correspondence relationship with the carrier, so that the terminal device may respectively determine whether the correspondence relationship between the two logical channels is configured for the repeated transmission function of the first radio bearer. Here, for example, the terminal device determines the correspondence between the first logical channel and the carrier, that is, the terminal device determines whether a parameter indicating that data in the first logical channel is transmitted only by using the first carrier is configured for the repeated transmission function of the first radio bearer.

For example, if the network device configures the corresponding relationship between the logical channel and the carrier according to one parameter, as an embodiment, the terminal device determines whether the parameter indicating that the data in the first logical channel is transmitted only by using the first carrier is configured for the repeated transmission function of the first radio bearer, and may implement the following steps: and judging whether the parameter is included in a message for configuring the repeat transmission function for the first radio bearer, wherein if the parameter is included in the message for configuring the repeat transmission function for the first radio bearer, the parameter is determined to be configured for the repeat transmission function of the first radio bearer, otherwise, the parameter is determined not to be configured for the repeat transmission function of the first radio bearer.

When configuring the duplicate transmission function for the first radio bearer, the network device may send a message, for example, an RRC message, to the terminal device, where the message is used to configure the duplicate transmission function for the first radio bearer, and generally, if the network device is to configure a correspondence between a logical channel and a carrier for the duplicate transmission function of the first radio bearer, the message is configured together with the RRC message, so that the terminal device may determine that the parameter is configured for the duplicate transmission function of the first radio bearer if it is determined that the parameter is carried in the RRC message, and may determine that the parameter is not configured for the duplicate transmission function of the first radio bearer if the parameter is not included in the RRC message. In this way, the terminal device can directly determine whether the parameter is configured for the retransmission function of the first radio bearer, which is relatively simple. In addition, the network device may perform the same determination process as the terminal device, and therefore, if the parameter is not configured for the repeated transmission function of the first radio bearer, both the terminal device and the network device may determine that the corresponding relationship between the first logical channel and the first carrier continues to be used, that is, both the terminal device and the network device transmit data in the first logical channel only by using the first carrier.

In this embodiment of the present application, if the terminal device determines that the parameter is not configured for the retransmission function of the first radio bearer, the terminal device and the network device may continue to use the parameter, so that after the retransmission function of the first radio bearer is deactivated, the parameter may also continue to be used without reconfiguration, thereby reducing the operation of the device and improving the utilization rate of the parameter.
