The antenna of a multi-card terminal can be time-division multiplexed on the UE corresponding to each USIM card, so the antenna capability of the UE corresponding to each USIM card in the multi-card terminal is periodically degraded. Taking the multi-card terminal as a dual-card terminal (i.e., a terminal with two USIM cards installed) as an example, the dual-card terminal can be a DR-DSDS (Dual Receive-Dual USIM Dual Standby) terminal or a DSDA (Dual USIM Dual Active) terminal. The following explains the problems caused by time-division multiplexing of DR-DSDS terminals and DSDA terminals:

The two USIM cards installed on the DR-DSDS terminal do not support dual-channel, but support dual reception on the two USIM cards. The antenna of the DR-DSDS terminal will be time-division multiplexed on the UE corresponding to card A (or main card) (recorded as UE1) and the UE corresponding to card B (or secondary card) (recorded as UE2). For example, the two antennas in the DR-DSDS terminal are always used for uplink data transmission and downlink data reception of UE1, and the other two antennas in the DR-DSDS terminal are used for UE2 to periodically receive paging or make measurements for a period of time, and the rest of the time is used for UE1 to receive downlink data. It can be seen that the downlink antenna capability of UE1 is periodically degraded. However, in the related art, the antenna configuration sent to UE1 by the network side device corresponding to UE1 may exceed the actual antenna capability currently possessed by UE1, resulting in UE1 data transmission failure. In addition, if UE1 is configured with SRS (Sounding Reference Signal) antenna selection (SRS antenna selection is also called: SRS antenna rotation, SRS antenna switching, SRS antenna Switching), UE1's SRS transmission on certain antennas may conflict in time with UE2's downlink data reception (receiving paging or making measurements), resulting in UE1 having to downgrade SRS transmission (originally using 2 antennas to send SRS at the same time, but now using 1 antenna to send SRS) or even being unable to send SRS, thereby affecting UE1's acquisition of downlink CSI (Channel State Information) quality.

The two USIM cards installed on the DSDA terminal support dual-channel, that is, the two USIM cards can send and receive at the same time. The antenna of the DSDA terminal will be time-division multiplexed on the UE corresponding to card A (referred to as UE1) and the UE corresponding to card B (referred to as UE2), and the uplink/downlink antenna capabilities of UE1 and UE2 are periodically degraded. However, in the related art, the antenna configuration sent by the network-side device corresponding to UE1 to UE1 may exceed the actual antenna capability currently possessed by UE1, resulting in UE1 data transmission failure. Similarly, the antenna configuration sent by the network-side device corresponding to UE2 to UE2 may exceed the actual antenna capability currently possessed by UE2, resulting in UE2 data transmission failure.

In view of the problems existing in the above-mentioned related technologies, the present application proposes that the UE informs the network side device of the antenna capability currently actually possessed by the UE by sending first indication information related to the antenna capability of the UE to the network side device, so that the network side device sends the antenna configuration matching the antenna capability currently actually possessed by the UE to the UE, thereby reducing the occurrence of UE data transmission failure. The data transmission method provided by the embodiment of the present application is described in detail below through some embodiments and their application scenarios in conjunction with the accompanying drawings.

In the first aspect, referring to FIG. 2 , which is a flowchart of an implementation method of a data transmission method provided in an embodiment of the present application, the method may include the following steps:

Step S201: User equipment UE sends first indication information to a network side device, where the first indication information is related to the antenna capability of the UE.

In an embodiment of the present application, UE sending the first indication information to the network side device refers to the UE corresponding to a USIM card of the multi-card terminal sending the first indication information to the network side device corresponding to the USIM card. For example, UE1 corresponding to card A of the DR-DSDS terminal or DSDA terminal sends the first indication information to the network side device corresponding to card A. In the following, unless otherwise specified, UE sending information to the network side device refers to: UE corresponding to a USIM card of the multi-card terminal sending the information to the network side device corresponding to the USIM card; similarly, UE receiving information sent by the network side device refers to: UE corresponding to a USIM card of the multi-card terminal receiving the information sent by the network side device corresponding to the USIM card. Among them, the multi-card terminal can be the terminal device 11 in Figure 1. For examples of terminal device 11, please refer to the previous text, which will not be repeated here.

In a possible implementation manner, the antenna capability of the UE includes at least one of the following:

The number of receive multiple-input multiple-output MIMO layers supported by the UE;

The number of receive antennas supported by the UE;

The number of receiving ports supported by the UE;

The receive antenna modes supported by the UE;

The number of transmit multiple-input multiple-output MIMO layers supported by the UE;

The number of transmit antennas supported by the UE;

The number of sending ports supported by the UE;

Transmit antenna modes supported by the UE;

The SRS antenna selection capability supported by the UE.

In specific implementation, the receiving antenna mode supported by the UE may be nRx, such as 4Rx and 2Rx, and the transmitting antenna mode supported by the UE may be mTx, such as 2Tx and 1Tx. The SRS antenna selection capability supported by the UE may be xTyR, such as 2T4R, 1T4R, 1T1R, and 1T2R, where 2T4R means that the UE can perform SRS transmission on 4 antennas. 1T4R means that the UE can send SRS on 4 antennas, and supports 1 antenna to send SRS in each round; 1T1R means that the UE can send SRS on 1 antenna, and supports 1 antenna to send SRS in each round; 1T2R means that the UE can send SRS on 2 antennas, and supports 1 antenna to send SRS in each round.

The first indication information is used to indicate at least one of the following:

Item A-1: Time division multiplexing information of antenna capabilities;

Item A-2: Request for change of antenna capability;

Item A-3: Sounding reference signal SRS cancellation indication;

Item A-4: Preference information of SRS resources.

For item A-1, the time division multiplexing information of the antenna capability is used to indicate the antenna capability actually possessed by the UE in different time periods. For example, the time division multiplexing information of the antenna capability can be used to indicate the transmit antenna modes supported by the UE in different time periods. For example, the time division multiplexing information of the antenna capability can be used to indicate that the UE supports 4Rx in the first time period and supports 2Rx in the second time period, and the first time period and the second time period appear periodically.

The UE sends the first indication information including the time division multiplexing information of the antenna capability to the network side device, so that the network side device can refer to the time division multiplexing information of the antenna capability sent by the UE, and send to the UE an antenna configuration that matches the antenna capability actually possessed by the UE in different time periods (matching means that the antenna capability required by the antenna configuration sent by the network side device to the UE is less than or equal to the antenna capability actually possessed by the UE), thereby avoiding the situation where the antenna configuration sent by the network side device to the UE is higher than the antenna capability actually possessed by the UE in different time periods, and effectively reducing the occurrence of UE data transmission failures. The situation where the first indication information is used to indicate the time division multiplexing information of the antenna capability will be described in detail in the first implementation mode below.

For item A-2, the antenna capability change request is used to indicate that the UE has undergone a change in antenna capability, or to request the network-side device to allow the UE to change its antenna capability. The change in the UE's antenna capability may be caused by the multi-card terminal coordinating the antenna capabilities between the UEs corresponding to multiple USIM cards. Taking the UE's antenna capability as an example, the UE's antenna capability is the SRS antenna selection capability supported by the UE. The change in the UE's antenna capability may be: the SRS antenna selection capability supported by UE1 corresponding to card A in the multi-card terminal was originally 2T4R, and one of the two antennas for sending SRS was switched to UE2 corresponding to card B. Therefore, the SRS antenna selection capability supported by UE1 is changed to 1T4R.

In a specific implementation, after the antenna capability has been changed, the UE may send the first indication information including the antenna capability change request to the network side to notify the network side device that the antenna capability has been changed. The UE may also send the first indication information including the antenna capability change request to the network side before changing the antenna capability to request the network side device to allow the UE to change the antenna capability, and after obtaining the permission of the network side device, the UE changes the antenna capability.

The UE sends the first indication information including the antenna capability change request to the network side device, so that the network side device can learn the changed antenna capability of the UE, and then send the reconfiguration information (i.e., the antenna configuration matching the changed antenna capability of the UE) to the UE. The case where the first indication information is used to indicate the antenna capability change request will be described in detail in Implementation Method 2.

For item A-3: SRS cancellation indication is used to instruct the UE to cancel SRS transmission. SRS cancellation indication is used to indicate At least one of the following:

Cancel the incoming SRS resources;

Cancel at least one SRS resource;

The SRS is transmitted using the degraded antenna on the upcoming SRS resource.

Among them, canceling the upcoming SRS resources is used to indicate that the UE will not use the SRS resources at the upcoming SRS sending time. The UE sends the first indication information including canceling the upcoming SRS resources to inform the network side device that the UE will not send SRS at the upcoming SRS sending time, and indirectly requests the network side device to release the transmission resources (for example: SRS resources) required by the UE's currently limited antenna capability. In this way, the network side device may not receive the SRS signal of the UE, and may also allocate an SRS resource that should be allocated to the UE to other UEs to optimize resource utilization. When the UE needs to send SRS, the UE may send the first indication information including the preference information of the SRS resource to the network side device to realize SRS sending. Regarding the situation in which the UE sends the first indication information including the preference information of the SRS resource to the network side device, please see the description of item A-4 below.

Canceling at least one SRS resource is used to indicate that the UE will not use the SRS resource at the upcoming SRS transmission time or multiple subsequent SRS transmission times. The UE sends the first indication information including the cancellation of at least one SRS resource to inform the network side device that the UE will not send the SRS at the upcoming SRS transmission time or multiple subsequent SRS transmission times. In this way, the network side device can allocate one or more SRS resources that should have been allocated to the UE to other UEs. Similarly, when the UE needs to send SRS, the UE can send the first indication information including the preference information of the SRS resource to the network side device to realize SRS transmission.

Using a downgraded antenna to send SRS on the upcoming SRS resources is used to indicate that the UE will downgrade the sending of SRS at the upcoming SRS sending moment (the UE originally used 2 antennas to send SRS at the upcoming SRS sending moment, and now the UE will use 1 antenna to send SRS at the upcoming SRS sending moment). The UE sends the first indication information including using a downgraded antenna to send SRS on the upcoming SRS resources, to inform the network side device that the UE will downgrade the sending of SRS at the upcoming SRS sending moment. In this way, the network side device can refer to the first indication information sent by the UE to use a downgraded antenna to send SRS on the upcoming SRS resources, and send to the UE an SRS antenna selection configuration that matches the SRS antenna selection capability actually possessed by the UE, thereby avoiding the SRS antenna selection configuration sent by the network side device to the UE being higher than the SRS antenna selection capability actually possessed by the UE, and effectively reducing the occurrence of UE failure to send SRS.

In specific implementation, if UE1 is configured with SRS antenna selection, UE1 recognizes in advance that the antenna that is about to send SRS will be switched to UE2, and UE1 will not be able to send SRS through this antenna. In this case, UE1 sends an SRS cancellation indication to the network side device, so that the network side device can refer to the SRS cancellation indication sent by UE1 and perform corresponding processing (for example: sending an SRS antenna selection configuration that matches the SRS antenna selection capability actually possessed by UE1 to UE1, or allocating one or more SRS resources that should have been allocated to the UE to other UEs). The case where the first indication information is used to indicate the SRS cancellation indication will be described in detail in Implementation Mode 3.

For item A-4: The preference information of the SRS resource is used to indicate the SRS resource that the UE expects to be configured, thereby indirectly requesting the network side device to reconfigure the transmission resources that the UE currently needs to use for the limited antenna capability. For example: temporarily configure an SRS resource, or reconfigure the SRS resource according to the SRS resource that the UE expects to be configured. In specific implementation, if UE1 misses SRS transmission in some cases (for example: the antenna that UE1 is about to send SRS is about to be switched to UE2, so UE1 misses SRS transmission), then UE1 can send a first indication message including preference information of the SRS resource to the network side device before the next SRS transmission time arrives, so as to request the network side device to temporarily allocate an SRS resource, so that UE1 can send SRS at the next SRS transmission time. Alternatively, if UE1 knows when the antenna will be switched to UE2, UE1 can send a first indication message including preference information of the SRS resource to the network side device to inform the network side device of the SRS resource that UE1 expects to be configured, thereby avoiding a time conflict between the SRS resource allocated by the network side device to UE1 and the downlink data reception (receiving paging or making measurements) of UE2.

It is understandable that the UE can first send the first indication information including one of items A-1 to A-4, and then send the first indication information including another item of items A-1 to A-4 according to the antenna capability currently actually possessed by the UE. Which item or items are included in the first indication information sent by the UE each time is not limited in the embodiment of the present application. For example: the UE first sends the first indication information including item A-3 (SRS cancellation indication) to the network side device, and then sends the first indication information including item A-4 (SRS resource preference information) to the network side device.

In a possible implementation manner, the data transmission method provided in the embodiment of the present application further includes:

The UE sends third indication information to the network side device, where the third indication information is used to indicate whether the UE supports sending the first indication information.

In a specific implementation, before executing the above step S201, the UE may also send a third indication message to the network side device to inform the network side device whether the UE supports reporting the first indication message. In this way, when the network side device receives the third indication message indicating that the UE supports reporting the first indication message, it may continue to wait for the first indication message, and then perform processing corresponding to the first indication message according to the first indication message (for example: sending time division multiplexing information of antenna configuration, SRS antenna selection configuration information, reconfiguration information to the UE, sending an SRS antenna selection configuration that matches the SRS antenna selection capability actually possessed by UE1 to UE1, allocating one or more SRS resources that should have been allocated to the UE to other UEs, temporarily allocating an SRS resource to the UE, and allocating the SRS resource that the UE expects to be configured to the UE).

In a possible implementation, the UE may use UE capability signaling or UAI signaling to send the first indication information, that is, the UE may send UE capability signaling or UAI signaling including the first indication information. In addition, when the UE uses UAI signaling to send the first indication information, the network side device may configure whether the UE can send the first indication information.

It can be seen from the above steps that in an embodiment of the present application, the UE informs the network side device of the antenna capability that the UE currently actually possesses by sending the first indication information related to the antenna capability of the UE to the network side device, and indirectly requests the network side device to release or reconfigure the transmission resources that need to be used by the UE's currently limited antenna capability, so that the network side device sends an antenna configuration that matches the UE's current actual antenna capability to the UE, thereby avoiding the situation where the network side device sends the UE an antenna configuration that is higher than the UE's current actual antenna capability, and effectively reducing the occurrence of UE data transmission failures.

Implementation Method 1

This implementation describes the case where the first indication information is used to indicate the time division multiplexing information of the antenna capability. The first implementation is described below in conjunction with FIG3. As shown in FIG3, the interaction between the UE and the network side device includes the following steps:

Step S301: The UE sends first indication information of time division multiplexing information indicating antenna capability to a network side device.

Step S302: The network side device sends the time division multiplexing information of the antenna configuration to the UE. Specifically, after the network side device receives the first indication information including the time division multiplexing information of the antenna capability sent by the UE, the network side device can refer to the time division multiplexing information of the antenna capability of the UE and send the time division multiplexing information of the antenna configuration to the UE, that is, the time division multiplexing information of the antenna configuration can be configured by the network side device according to the time division multiplexing information of the antenna capability of the UE, so as to send to the UE an antenna configuration that matches the antenna capability actually possessed by the UE in different time periods (matching means that the antenna capability required by the antenna configuration sent by the network side device to the UE is less than or equal to the antenna capability actually possessed by the UE). It can be understood that the network side device can also refer to the time division multiplexing information of the antenna capability reported by the UE, and dynamically indicate the UE downlink MIMO layer by sending DCI to the UE, so as to avoid instructing the UE to use an antenna capability higher than the current actual antenna capability of the UE for data transmission, thereby effectively avoiding UE data transmission failure.

Step S303: The UE receives the time division multiplexing information of the antenna configuration sent by the network side device, and performs antenna configuration that matches the actual antenna capability it possesses in different time periods according to the time division multiplexing information of the antenna configuration sent by the network side device.

In a possible implementation, the time division multiplexing information of the antenna configuration is: antenna time division multiplexing pattern TDM pattern configuration information or antenna gap configuration information, wherein the antenna TDM pattern configuration information is used to indicate the antenna capabilities of multiple time periods configured by the network side device for the UE, and the antenna gap configuration information is used to indicate whether the network side device has configured gap periods for the antenna capabilities of the UE in multiple time periods. For example, the antenna gap information sent by the network side device to the UE is: the network side device configures 4 downlink MIMO layers for the UE, of which 2 downlink MIMO layers are additionally configured with gap information. The gap information includes: the duration of the gap, the repetition period of the gap, and the offset value/starting position of the gap. After the UE performs antenna configuration according to the antenna gap information, 2 downlink MIMO layers are always used for UE1, and the other 2 downlink MIMO layers are used for UE2 during the gap period, and for UE1 during the non-gap period.

In a possible implementation manner, in addition to sending the time division multiplexing information of the antenna configuration to the UE, in order to avoid time conflict caused by inconsistency between the time division multiplexing information of the SRS antenna selection configuration of the UE and the antenna capability reported by the UE, the network side device may also send the SRS antenna selection configuration information to the UE in the following two cases. The UE receives the SRS antenna selection configuration information sent by the network side device, and then may perform the SRS antenna selection configuration that matches the SRS antenna selection capability actually possessed by the UE according to the SRS antenna selection configuration information sent by the network side device:

The first case: Since the time division multiplexing information of the UE's antenna capability can indirectly reflect the time division multiplexing information of the UE's SRS antenna selection capability, the network side device can infer the time division multiplexing information of the UE's SRS antenna selection capability based on the time division multiplexing information of the UE's antenna capability, and then send the SRS antenna selection configuration information to the UE. That is, the network side device can configure the SRS antenna selection configuration information for the UE according to the time division multiplexing information of the UE's antenna capability.

The second case: the UE reports the time division multiplexing information of the UE's SRS antenna selection capability to the network side device, and the network side device can send the SRS antenna selection configuration information to the UE according to the time division multiplexing information of the SRS antenna selection capability reported by the UE, that is, the network side device can configure the SRS antenna selection configuration information for the UE according to the time division multiplexing information of the SRS antenna selection capability of the UE. It can be understood that the time division multiplexing information of the SRS antenna selection capability reported by the UE corresponding to the USIM card of different multi-card terminals can be different. For example: the time division multiplexing information of the SRS antenna selection capability reported by the UE corresponding to the USIM card of a multi-card terminal is: the UE supports antenna 1 and antenna 3 to send SRS simultaneously in the first time period, and supports antenna 2 and antenna 4 to send SRS simultaneously in the second time period; the time division multiplexing information of the SRS antenna selection capability reported by the UE corresponding to the USIM card of another multi-card terminal is: the UE supports antenna 1 and antenna 2 to send SRS simultaneously in the first time period, and supports antenna 3 and antenna 4 to send SRS simultaneously in the second time period.

In a possible implementation manner, the SRS antenna selection configuration information includes at least one of the following:

SRS resources;

SRS antenna port;

The mapping relationship between SRS resources and SRS antenna ports.

In a possible implementation manner, the SRS antenna selection configuration information further includes:

The time division multiplexing information of the SRS antenna selection configuration is used to indicate the SRS antenna selection capability of multiple time periods configured by the network side device for the UE.

Among them, SRS resources are transmission resources allocated by the network side device to the UE for sending SRS. SRS antenna port is the antenna port used when sending SRS. The mapping relationship between SRS resources and SRS antenna ports is used by the UE to determine which SRS resource will be used by which SRS antenna port to send SRS. The time division multiplexing information of the SRS antenna selection configuration can be: the UE uses the first SRS antenna selection configuration (for example: 2T4R) in the first time period, and the second SRS antenna selection configuration (for example: 1T4R or 1T2R) in the second time period.

Implementation Method 2

This implementation method describes the situation where the first indication information is used to indicate an antenna capability change request. In this implementation method, the UE can report the first antenna capability information and the second antenna capability information to the network side device in advance, and then trigger the antenna capability change, and send the first indication information including the antenna capability change request to the network side device. The second implementation method is described below in conjunction with Figure 4. As shown in Figure 4, the interaction between the UE and the network side device includes the following steps:

Step S401: The UE sends first antenna capability information and second antenna capability information to the network side device, where the first antenna capability information is used to indicate the baseline antenna capability of the UE, and the second antenna capability information is used to indicate the restricted antenna capability of the UE based on the baseline antenna capability. Taking the example that the UE's antenna capability is the SRS antenna selection capability supported by the UE, the UE uses UE capability signaling to send the first SRS antenna selection capability information and the second SRS antenna selection capability information to the network side device. The first SRS antenna selection capability is used to indicate the SRS antenna selection baseline capability (for example: 2T4R), and the second SRS antenna selection capability is used to indicate the SRS antenna selection capability used after the antenna capability is changed (for example: 1T2R). For example, the first SRS antenna selection capability information is supportedSRS-TxPortSwitch, and the second SRS antenna selection capability is used to indicate the SRS antenna selection capability used after the antenna capability is changed. The capability information is supportedSRS-TxPortSwitch_MUSIM.

Step S402: The network side device sends configuration information to the UE, where the configuration information is the antenna configuration that matches the first antenna capability information. After receiving the configuration information, the UE performs antenna configuration according to the configuration information. Taking the case where the antenna capability of the UE is the SRS antenna selection capability supported by the UE as an example, the UE receives the SRS antenna selection configuration information that matches the first SRS antenna selection capability information, and performs SRS antenna selection configuration.

Step S403: The UE sends a first indication message including an antenna capability change request to the network side device. After the UE has changed its antenna capability or before the UE changes its antenna capability, the UE may send a first indication message including an antenna capability change request to the network side device. The antenna capability change request is used to indicate that the UE's antenna capability is to be switched to the UE corresponding to other USIM cards of the multi-card terminal, as well as information such as the number of antenna capabilities to be switched. In specific implementation, the UE may use low-layer signaling such as UAI signaling, MAC CE signaling, or UCI signaling to send the first indication message including the antenna capability change request, thereby shortening the transmission delay of the antenna capability change request.

Step S404: The UE receives the reconfiguration information (i.e., antenna capability reconfiguration information) sent by the network side device, and the reconfiguration information is the antenna configuration that matches the second antenna capability information (i.e., the antenna capability reconfiguration information is configured by the network side device according to the limited antenna capability indicated by the second antenna capability information). After receiving the reconfiguration information, the UE reconfigures the antenna according to the reconfiguration information. Taking the example that the antenna capability of the UE is the SRS antenna selection capability supported by the UE, the UE receives the SRS antenna selection configuration information that matches the second SRS antenna selection capability information, and reconfigures the SRS antenna selection.

Implementation Method 3

This implementation describes the case where the first indication information is used to indicate the SRS cancellation indication. The third implementation is described below in conjunction with FIG5. As shown in FIG5, the interaction between the UE and the network side device includes the following steps:

Step S501: The UE receives SRS antenna selection configuration information sent by a network side device.

Step S502: The UE sends first indication information for indicating SRS cancellation indication to the network side device.

In specific implementation, if the UE is configured with SRS antenna selection, the UE can perform SRS antenna selection configuration according to the SRS antenna selection configuration information sent by the network-side device, and then use the SRS transmission antenna to send SRS at the SRS transmission time. However, if the UE recognizes in advance that the antenna that is about to send SRS will be switched to the UE corresponding to other USIM cards of the multi-card terminal, resulting in the UE being unable to send SRS through the antenna, in this case, the UE sends a first indication message including an SRS cancellation indication to the network-side device, so that the network-side device can refer to the SRS cancellation indication sent by the UE and perform corresponding processing (for example: sending an SRS antenna selection configuration that matches the SRS antenna selection capability actually possessed by UE1 to UE1, or allocating one or more SRS resources that should have been allocated to the UE to other UEs).

Implementation Method 4

This embodiment describes a situation where the time division multiplexing information of the antenna configuration received by the UE conflicts with the SRS antenna selection configuration information of the UE, wherein the SRS antenna selection configuration information of the UE may be the SRS antenna selection configuration information of the UE itself, that is, the SRS antenna selection configuration of the UE set by factory default. In the case where the network side device sends the SRS antenna selection configuration information to the UE, the SRS antenna selection configuration information of the UE may be the SRS antenna selection configuration information of the network side device. That is, in specific implementation, the UE's own SRS antenna selection configuration information may conflict with the time division multiplexing information of the antenna configuration received by the UE, or the SRS antenna selection configuration information received by the UE may conflict with the time division multiplexing information of the antenna configuration received by the UE.

The time division multiplexing information of the antenna configuration received by the UE conflicts with the SRS antenna selection configuration information of the UE, which may be: partial conflict (i.e., the time period in the time division multiplexing information of the antenna configuration partially overlaps with the time period indicated by the SRS resource in the SRS antenna selection configuration information), full conflict (i.e., the time period in the time division multiplexing information of the antenna configuration completely overlaps with the time period indicated by the SRS resource in the SRS antenna selection configuration information), or the time difference between the two is less than a predefined duration (for example: there is a gap between the time period in the time division multiplexing information of the antenna configuration and the time period indicated by the SRS resource in the SRS antenna selection configuration information, but the gap is short and there is no time for RF link switching).

To this end, this embodiment proposes to introduce a priority rule into the process of UE performing SRS transmission to resolve the conflict between the time division multiplexing information of the antenna configuration and the SRS antenna selection configuration information.

When the time division multiplexing information of the antenna configuration received by the UE conflicts with the SRS antenna selection configuration information received by the UE, the UE may determine whether to perform SRS transmission according to the priority rule. Specifically, there are two implementation methods:

A first implementation mode: the UE determines whether to send the SRS according to a priority rule agreed upon in the protocol.

For example, the protocol stipulates that when the antenna for UE's SRS transmission is in the gap period of the antenna, the UE should give priority to the gap period of the antenna, and the UE will not perform SRS transmission temporarily.

The second implementation mode: the UE determines whether to send SRS according to the priority ranking set by itself. Specifically, it includes:

When the priority order set by the UE itself is that the time division multiplexing information of the antenna configuration is prioritized, the UE determines not to perform SRS transmission; when the priority order set by the UE itself is that the SRS antenna selection configuration information is prioritized, the UE determines to perform SRS transmission.

For example, if the priority order set by the UE itself is that the priority of the antenna sending SRS is higher than the gap period of the antenna, the UE performs SRS transmission. On the contrary, if the priority order set by the UE itself is that the priority of the antenna sending SRS is lower than the gap period of the antenna, the UE temporarily does not perform SRS transmission.

In a possible implementation, the UE sends a second indication message to the network side device, and the second indication message is a priority ranking set by the UE itself. In a specific implementation, the second indication message sent by the UE to the network side may include the priority parameters of the time division multiplexing information of the antenna configuration and the SRS antenna selection configuration information. In this way, the network side device can learn the priority ranking tendency of the UE for the time division multiplexing information of the antenna configuration and the SRS antenna selection configuration information based on the second indication message. When it is learned that the priority of the SRS antenna selection configuration information is high and the UE is about to send the SRS, the network side device waits to receive the SRS that the UE is about to send; when it is learned that the priority of the time division multiplexing information of the antenna configuration is high and the UE does not send the SRS for the time being, it performs corresponding processing (for example: allocating an SRS resource that should have been allocated to the UE to other UEs).

In a second aspect, as shown in FIG6 , an embodiment of the present application provides another data transmission method, which at least includes The following steps are included:

Step S601: a network side device receives first indication information sent by a user equipment UE, where the first indication information is related to an antenna capability of the UE;

Among them, the first indication information is used to indicate at least one of the following: time division multiplexing information of antenna capability, antenna capability change request, sounding reference signal SRS cancellation indication, and SRS resource preference information; the time division multiplexing information of antenna capability is used to indicate the antenna capability of the UE in multiple time periods; the antenna capability change request is used to indicate that the UE has an antenna capability change, or to request the network side device to allow the UE to change the antenna capability; the SRS cancellation indication is used to instruct the UE to cancel SRS sending; the SRS resource preference information is used to indicate the SRS resources that the UE expects to be configured.
