Detailed Description

The technical solutions in the present application will be described below with reference to the accompanying drawings.

Fig. 1 is a wireless communication system 100 to which embodiments of the present application apply. The wireless communication system 100 may include a network device 110, a network device 120, and a User Equipment (UE) 130. Network device 110 and network device 120 may communicate with UE 130. Network device 110 and network device 120 may provide communication coverage for a particular geographic area and may communicate with UEs 130 located within that coverage area. UE130 may access a network (e.g., a wireless network) through network device 110 and network device 120. Optionally, the wireless communication system 100 may further include a network controller, a mobility management entity, and other network entities, which are not limited in this embodiment of the present application.

It should be understood that the technical solution of the embodiments of the present application may be applied to various communication systems, for example: fifth generation (5th generation,5G) systems or New Radio (NR), long term evolution (long term evolution, LTE) systems, LTE frequency division duplex (frequency division duplex, FDD) systems, LTE time division duplex (time division duplex, TDD), and the like. The technical scheme provided by the application can also be applied to future communication systems, such as a sixth generation mobile communication system, a satellite communication system and the like.

The UE in the embodiments of the present application may also be referred to as a Terminal device, an access Terminal, a subscriber unit, a subscriber station, a Mobile Station (MS), a Mobile Terminal (MT), a remote station, a remote Terminal, a mobile device, a user Terminal, a wireless communication device, a user agent, or a user equipment. The UE in the embodiments of the present application may be a device that provides voice and/or data connectivity to a user, and may be used to connect people, things, and machines, for example, a handheld device with a wireless connection function, an in-vehicle device, and so on. The UE in the embodiments of the present application may be a mobile phone (mobile phone), a tablet (Pad), a notebook, a palm, a mobile internet device (mobile internet device, MID), a wearable device, a Virtual Reality (VR) device, an augmented reality (augmented reality, AR) device, a wireless terminal in industrial control (industrial control), a wireless terminal in unmanned (self driving), a wireless terminal in teleoperation (remote medical surgery), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation security (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), and the like. Alternatively, the UE may be used to act as a base station. For example, the UEs may act as scheduling entities that provide side-uplink signals between UEs in V2X or D2D, etc. For example, a cellular telephone and a car communicate with each other using side-link signals. Communication between the cellular telephone and the smart home device is accomplished without relaying communication signals through the base station.

The network device in the embodiments of the present application may be a device for communicating with the UE, which may also be referred to as an access network device or a radio access network device, e.g. the network device may be a base station. The network device in the embodiments of the present application may refer to a radio access network (radio access network, RAN) node (or device) that accesses the UE to the wireless network. The base station may broadly cover or replace various names in the following, such as: a node B (NodeB), an evolved NodeB (eNB), a next generation NodeB (gNB), a relay station, an access point, a transmission point (transmitting and receiving point, TRP), a transmission point (transmitting point, TP), a master MeNB, a secondary SeNB, a multi-mode wireless (MSR) node, a home base station, a network controller, an access node, a wireless node, an Access Point (AP), a transmission node, a transceiving node, a baseband unit (BBU), a remote radio unit (Remote Radio Unit, RRU), an active antenna unit (active antenna unit, AAU), a radio head (remote radio head, RRH), a Central Unit (CU), a Distributed Unit (DU), a positioning node, and the like. The base station may be a macro base station, a micro base station, a relay node, a donor node, or the like, or a combination thereof. For ease of understanding, the network device may also be referred to hereinafter as a base station.

In some embodiments, the base station may be fixed or mobile. For example, a helicopter or drone may be configured to act as a mobile base station, and one or more cells may move according to the location of the mobile base station. In other examples, a helicopter or drone may be configured to act as a device to communicate with another base station. In some embodiments, a base station may refer to CU or DU, or a base station may include CU and DU, or a base station may also include AAU.

It should be appreciated that the base station may be deployed on land, including indoors or outdoors, hand-held or vehicle-mounted; the device can be deployed on the water surface; but also on aerial planes, balloons and satellites. In the embodiment of the present application, the base station and the scene in the embodiment of the present application are not limited. It should also be understood that all or part of the functions of the base station and UE in this application may also be implemented by software functions running on hardware, or by virtualized functions instantiated on a platform (e.g., a cloud platform).

To increase the data transmission rate of UEs, some communication systems introduce communication in a multi-band scenario, such as carrier aggregation (carrier aggregation, CA), dual connectivity (dual connectivity, DC), LTE and NR dual connectivity (LTE NR dual connectivity, EN-DC), and so on.

In a multi-band scenario, multiple carriers operating simultaneously may be configured for a UE. For example, the UE may operate in a band combination of bands (band) X and band Y. Wherein, band X may be a frequency division duplex (frequency division duplex, FDD) band, and band Y may be a time division duplex (time division duplex, TDD) band.

Taking fig. 1 as an example, the network device 110 may send a downlink signal through band X, the network device 120 may send a downlink signal through band Y, the UE130 is located in the coverage areas of the network device 110 and the network device 120, and the UE130 may communicate with the network device 110 and the network device 120 at the same time, where the UE130 may operate in a frequency band combination formed by band X and band Y.

However, in the case where UE130 operates in a band combination of band X and band Y, transmission between band X and band Y may cause interference to reception. For example, the transmission signal harmonic of band X may interfere with the reception signal of band Y, and at the same time, the transmission signal of band Y may interfere with the reception signal of band X with a relatively close frequency spectrum, so that if the interference is relatively serious, the UE may not support simultaneous transceiving of two frequency bands (or multiple frequency bands).

The simultaneous transceiving capability of the UE means: whether the UE is capable of supporting the transmission of one frequency band signal while receiving another frequency band signal. The simultaneous transceiving capability of the UE may represent an interference suppression capability of the UE between two frequency bands or a reception demodulation capability of the UE. Whether the UE can support simultaneous reception and transmission (hereinafter referred to as simultaneous transceiving) on one frequency band combination can be reported to the base station through UE capability information.

If the UE does not support simultaneous transceiving on a certain frequency band combination (for example, the frequency band combination may include two frequency bands), the base station needs to avoid that the UE receives one frequency band signal and transmits another frequency band signal overlapping in time when scheduling the frequency band combination. That is, when the base station schedules the frequency band combination, the base station can only transmit signals on the frequency band combination at the same time or receive signals on the frequency band combination at the same time for the UE. If the UE supports simultaneous transceiving on a certain frequency band combination (for example, the frequency band combination may include two frequency bands), the base station needs to avoid that the UE receives one frequency band signal and transmits another frequency band signal overlapping in time beyond the capability range of the UE when scheduling the frequency band combination.

However, in an actual network, two (or more) base stations in different frequency bands may not be co-sited or the two base stations are not synchronized, which may cause a certain time difference between downlink signals of the two base stations received by the UE. In addition, if the two base stations are located at different positions, the distances from the UE to the two base stations will be different, and the time between the downlink signals sent by the two base stations and the UE will also be different.

As shown in fig. 1, the distance between network device 110 and UE130 is smaller than the distance between network device 120 and UE130, and if network device 110 and network device 120 send downlink signals to UE130 at the same time, the downlink signals sent by network device 110 will reach UE130 before the downlink signals sent by network device 120. For example, as shown in fig. 1, when the time from the downlink signal sent by the network device 110 to the UE130 is t1, and the time from the downlink signal sent by the network device 120 to the UE130 is t2, the time difference between the time from the downlink signals sent by the two network devices to the UE130 is t2-t1.

As shown in fig. 2, the signal 110s is a signal transmitted between the network device 110 and the UE130 in fig. 1, the signal 120s is a signal transmitted between the network device 120 and the UE130 in fig. 1, the time difference may cause overlapping of an uplink signal (denoted by "U" in fig. 2) in the signal 110s and a downlink signal (denoted by "D" in fig. 2) in the signal 110s, interference may occur between the overlapping signals, when the time difference is relatively small, the affected transmission symbol ratio is relatively small, and when the time difference is relatively large, the affected symbol ratio is relatively large. At this time, if the UE does not support simultaneous transceiving on the band combination (for example, the band combination may include two bands), the UE may not work normally on the band combination when the time difference is relatively large. If the UE supports simultaneous transceiving on the frequency band combination (for example, the frequency band combination may include two frequency bands), when the time difference exceeds a certain value, simultaneous transmission and simultaneous reception between the two frequency bands by the UE are difficult to ensure, so that the UE cannot work normally on the frequency band combination. For example, as shown in fig. 2, if the maximum downlink time difference that the UE can transmit and receive simultaneously is 33 microseconds (μs), the overlapping portion of the uplink signal (denoted by "U" in fig. 2) in the signal 110s and the downlink signal (denoted by "D" in fig. 2) in the signal 110s is greater than 33 μs, the simultaneous transmission and reception capability of the UE is exceeded, and the UE cannot operate normally in the frequency band combination.

To address one or more of the above problems, embodiments of the present application are described in detail below in conjunction with fig. 3.

Fig. 3 is a schematic flow chart of a communication method according to an embodiment of the present application. It should be understood that fig. 3 illustrates steps or operations of a communication method, but these steps or operations are merely examples, and embodiments of the present application may perform other operations or variations of the operations in fig. 3, or not all steps need to be performed, or the steps may be performed in other orders. The method 300 shown in fig. 3 may include steps S310 and S320, which are specifically as follows:

s310, the UE sends first information to a first base station.

The first information may be used to determine a transceiver interference between the first frequency band and the second frequency band. The UE may communicate with the first base station over the first frequency band and the UE may communicate with a second base station over the second frequency band.

Optionally, the first information may also be used to deactivate (disable) the carrier of the first frequency band, or the first information may also be used to adjust the time of transmission of the first downlink signal on the first frequency band, so as to reduce the difference between the time when the first downlink signal arrives at the UE and the time when the second downlink signal transmitted on the second frequency band arrives at the UE. The first downlink signal may be a downlink signal sent by the first base station in the first frequency band, and the second downlink signal may be a downlink signal sent by the second base station in the second frequency band.

Optionally, the first information may include at least one of: the method comprises the steps of enabling a first downlink signal to reach the UE, enabling a second downlink signal to reach the UE, enabling a difference value between the time when the first downlink signal reaches the UE and the time when the second downlink signal reaches the UE, enabling a duty ratio of the difference value in one transmission symbol, enabling a duty ratio of the difference value in one time slot (slot), enabling first indication information, enabling a network scene with the simultaneous transceiving capability of the UE to be applicable, and enabling the UE to simultaneously transceiving maximum downlink time difference.

The first indication information may be used to indicate that a difference between a time when the first downlink signal arrives at the UE and a time when the second downlink signal arrives at the UE is greater than a first threshold, and the UE simultaneous transceiving capability may be used to indicate whether the UE supports simultaneous transceiving on the first frequency band and the second frequency band.

Alternatively, the first threshold may be determined by the UE, network configured, or protocol specified.

Alternatively, the first threshold may be a maximum downlink time difference that the UE can transmit and receive simultaneously. For example, the maximum downlink time difference that the UE can transmit and receive simultaneously may be 33 μs.

The first information may also be used to indicate a carrier of the first frequency band and a carrier of the second frequency band.

In this embodiment of the present application, the frequency band included in the frequency band combination where the first frequency band and the second frequency band are located may be more than two (the frequency band combination may include three or more frequency bands), and in this case, a plurality of spoke carriers may exist in the frequency band combination. In this case, interference of transmission to reception may not occur between all carriers in the band combination, but only some of them.

For example, the band combination may include three bands, band X, band Y, and band Z, where band X is a primary carrier and band Y and band Z are spoke carriers. At this time, if interference of transmission to reception occurs between the band X and the band Y, the first information may indicate a carrier of the band X and a carrier of the band Y, or the first information may indicate band information of the band X and band information of the band Y, or the first information may indicate other information that can indicate the band X and the band Y.

The first information may also be used to indicate a network scenario in which the simultaneous transceiving capability of the UE is applicable.

The network scenario where the simultaneous transceiving capability of the UE is applicable may include at least one of the following scenarios: a co-sited deployment scenario, a non-co-sited deployment scenario, an inter-base station synchronization scenario, and an inter-base station non-synchronization scenario.

The co-station deployment scenario may refer to co-station between the first base station and the second base station, the non-co-station deployment scenario may refer to non-co-station between the first base station and the second base station, the inter-base station synchronization scenario may refer to synchronization (or may also be referred to as timing synchronization) between the first base station and the second base station, and the inter-base station non-synchronization scenario may refer to non-synchronization between the first base station and the second base station.

For example, a network scenario where the simultaneous transceiving capability of the UE is applicable may be co-sited deployment and inter-base station synchronization; or, the network scenario where the simultaneous transceiving capability of the UE is applicable may be co-sited deployment but unsynchronized between base stations; or, a network scenario where the simultaneous transceiving capability of the UE is applicable may be a synchronous but non-co-sited deployment between base stations; or, the network scenario where the simultaneous transceiving capability of the UE is applicable may be non-co-sited deployment and non-synchronization between base stations.

And S320, the first base station deactivates the carrier wave of the first frequency band according to the first information, or the first base station adjusts the sending time of the first downlink signal on the first frequency band according to the first information.

Optionally, the carriers of the first frequency band in the first frequency band and the second frequency band may be secondary carriers, and correspondingly, the carriers of the second frequency band may be primary carriers or primary secondary carriers. That is, the first base station may deactivate secondary carriers in the first frequency band and the second frequency band (e.g., carriers of the first frequency band) according to the first information.

As described in the foregoing embodiments, in the embodiments of the present application, a band combination may include more than two bands, and at the same time, only transmission-to-reception interference may be generated between some carriers in the band combination, and at this time, the base station may deactivate (disable) a spoke carrier in the interference-generating partial carrier, and reserve the primary carrier and the spoke carrier without interference.

For example, a band combination may include three bands, band X, band Y, and band Z, where band X is the primary carrier and band Y and band Z are the spoke carriers. At this time, if interference of transmission to reception occurs between band X and band Y, the base station may deactivate the carrier of band Y where the interference is transmitted.

Optionally, the first base station adjusts the sending time of the first downlink signal on the first frequency band according to the first information, so as to reduce the difference between the time when the first downlink signal arrives at the UE and the time when the second downlink signal sent on the second frequency band arrives at the UE.

In some embodiments, before the S320, the UE may further send second information to a base station, where the second information is used to indicate the simultaneous transceiving capability of the UE.

Optionally, the first base station may deactivate the carrier of the first frequency band according to the first information and/or the second information, or the first base station may adjust the transmission time of the first downlink signal on the first frequency band according to the first information and/or the second information.

Optionally, the second information may also include a network scenario where the simultaneous transceiving capability of the UE is applicable. As in the previous embodiment, the network scenario where the simultaneous transceiving capability of the UE is applicable may include at least one of the following scenarios: a co-sited deployment scenario, a non-co-sited deployment scenario, an inter-base station synchronization scenario, and an inter-base station non-synchronization scenario.

At this time, the first base station may deactivate the carrier of the first frequency band according to a network scenario where the simultaneous transceiving capability of the UE is applicable, or adjust the sending time of the first downlink signal on the first frequency band. For example, if the network scenario in which the first base station is located is different from the network scenario, the first base station may deactivate the carrier of the first frequency band, or adjust the transmission time of the first downlink signal on the first frequency band.

Optionally, the second information may further include a maximum downlink time difference that the UE can send and receive simultaneously. At this time, the first base station may deactivate the carrier of the first frequency band according to the maximum downlink time difference that the UE can transmit and receive simultaneously, or adjust the transmission time of the first downlink signal on the first frequency band. The specific processing method may refer to the subsequent embodiments, and will not be described herein.

Alternatively, the first information and the second information may be the same information, or the first information and the second information may be sent by the same information or message.

In the embodiment of the present application, before S320, it may also be determined by the UE or the first base station whether the S320 needs to be performed. Several possible implementations of the embodiments of the present application are described below according to the information or content included in the first information.

In some embodiments, the first information may include a time at which the first downlink signal arrives at the UE and a time at which the second downlink signal arrives at the UE.

At this time, before S310, the UE may further receive the first downlink signal and the second downlink signal, and determine a time when the first downlink signal arrives at the UE and a time when the second downlink signal arrives at the UE. The first downlink signal may be sent by the first base station to the UE on the first frequency band, and the second downlink signal may be sent by the second base station to the UE on the second frequency band.

Optionally, after receiving the first information, the first base station may deactivate the carrier of the first frequency band according to the first information, or adjust a transmission time of the first downlink signal on the first frequency band.

For example, the first base station may determine a difference between a time when the first downlink signal arrives at the UE and a time when the second downlink signal arrives at the UE according to the first information. At this time, the first base station may deactivate the carrier of the first frequency band according to the difference value, or adjust the transmission time of the first downlink signal on the first frequency band.

Optionally, the first base station may determine whether the difference exceeds a second threshold, and deactivate the carrier of the first frequency band if the difference is greater than the second threshold, or adjust the transmission time of the first downlink signal on the first frequency band. Optionally, the second threshold may be determined by the UE, network configured, or protocol specified.

Alternatively, the second threshold may be a maximum downlink time difference that the UE can transmit and receive simultaneously. For example, the maximum downlink time difference that the UE can transmit and receive simultaneously may be 33 μs.

In some embodiments, the first information may include a difference between a time when the first downlink signal arrives at the UE and a time when the second downlink signal arrives at the UE, a duty cycle of the difference in one transmission symbol, or a duty cycle of the difference in one slot.

At this time, before the S310, the UE may receive the first downlink signal and the second downlink signal and determine a difference between a time when the first downlink signal arrives at the UE and a time when the second downlink signal arrives at the UE.

Optionally, the first base station may determine whether the difference exceeds a second threshold, and deactivate the carrier of the first frequency band if the difference is greater than the second threshold, or adjust the transmission time of the first downlink signal on the first frequency band.

In some embodiments, the first information may further include the first indication information, and the first indication information may indicate that a difference between a time when the first downlink signal arrives at the UE and a time when the second downlink signal arrives at the UE is greater than a first threshold.

At this time, before S310, the UE may receive the first downlink signal and the second downlink signal, determine a difference between a time when the first downlink signal arrives at the UE and a time when the second downlink signal arrives at the UE, and determine whether a difference between the time when the first downlink signal arrives at the UE and the time when the second downlink signal arrives at the UE is greater than a first threshold.

Optionally, the first base station may deactivate the carrier of the first frequency band or adjust the transmission time of the first downlink signal on the first frequency band when the first indication information indicates that the difference between the time when the first downlink signal arrives at the UE and the time when the second downlink signal arrives at the UE is greater than the first threshold.

Optionally, the first indication information is 1-bit indication information.

For example, when the first indication information is 1, it may indicate that a difference between a time when the first downlink signal arrives at the UE and a time when the second downlink signal arrives at the UE is greater than a first threshold; when the first indication information is 0, it may indicate that a difference between a time when the first downlink signal arrives at the UE and a time when the second downlink signal arrives at the UE is less than or equal to the first threshold. Of course, the first indication information may also indicate by other manners, which is not limited in the embodiment of the present application.

In some embodiments, the first information may include a network scenario in which simultaneous transceiving capability of the UE is applicable.

At this time, the first base station may determine whether a network scenario in which the first base station is located is consistent with a network scenario applicable to the simultaneous transceiving capability of the UE.

Optionally, when the network scenario where the first base station is located is different from the network scenario where the simultaneous transceiving capability of the UE is applicable, the first base station may deactivate the carrier of the first frequency band, or adjust the sending time of the first downlink signal on the first frequency band.

For example, assuming that the network scenario where the first base station is located is co-located between the first base station and the second base station, the first information sent by the UE indicates that the network scenario where the simultaneous transceiving capability of the UE is applicable is co-located and synchronized between the first base station and the second base station, then, at this time, the network scenario where the first base station is located is different from the network scenario where the simultaneous transceiving capability of the UE is applicable, the first base station may deactivate the carrier wave of the first frequency band, or adjust the sending time of the first downlink signal on the first frequency band.

It should be noted that, in general, if the simultaneous transceiving capability of the UE supports non-co-sited deployment, it means that it may also support co-sited deployment, because a time difference between downlink signals reaching the UE between multiple frequency bands of the co-sited deployment is 0. Also, if the simultaneous transceiving capability of a UE supports asynchronous deployment, it means that it can also support synchronous deployment. Optionally, if the UE does not report the network scenario where the simultaneous transceiving capability of the UE is applicable, the UE may default to have no limitation of the network deployment scenario.

In some embodiments, the first information may include a maximum downlink time difference that the UE can transmit and receive simultaneously.

At this time, the first base station may deactivate the carrier of the first frequency band according to the first information, or adjust the transmission time of the first downlink signal on the first frequency band.

For example, the first base station may determine the position of the UE in the cell corresponding to the first base station, determine the worst receiving position in the cell according to the maximum downlink time difference that the UE can send and receive simultaneously, and then determine whether to execute S320, that is, deactivate the carrier of the first frequency band, or adjust the sending time of the first downlink signal on the first frequency band according to the position of the UE in the cell corresponding to the first base station and the worst receiving position. The specific method for determining the worst receiving position may refer to the prior art, and this will not be described in detail in the embodiments of the present application.

Method embodiments of the present application are described above in detail in connection with fig. 1-3, and apparatus embodiments of the present application are described below in detail in connection with fig. 4-6. It is to be understood that the description of the method embodiments corresponds to the description of the device embodiments, and that parts not described in detail can therefore be seen in the preceding method embodiments.
