Please refer to FIG. 2. FIG. 2 is a flowchart of a transmission control method according to an embodiment of the present invention. The method is applied to a terminal. As shown in FIG. 2, it includes the following steps:

Step 201: Receive downlink control information DCI;

Step 202: Determine the control information of the physical uplink shared channel PUSCH transmission scheduled by the DCI according to the target identifier associated with the DCI.

It should be understood that, within a time period, the terminal may only receive the DCI sent by one TRP, or may receive multiple DCIs sent by multiple TRPs.

Optionally, the transmission of the PUSCH scheduled by the DCI may include the transmission of scheduled uplink data, and may also include the transmission of a resource set (resource set) used to activate an aperiodic sounding reference signal (Sounding Reference Signal, SRS) on the PUSCH.

In an embodiment, the above-mentioned control information may include indication information for activating the SRS resource set. Optionally, when the control information includes indication information for activating the SRS resource set, after determining the control information for the physical uplink shared channel PUSCH transmission scheduled by the DCI according to the target identifier associated with the DCI, The method also includes:

Activate the aperiodic SRS resource set associated with the target identifier.

In the embodiment of the present invention, the above-mentioned target identifier may be understood as a TRP identifier or associated information corresponding to the TRP in a one-to-one manner, which is not further limited here. Each target identifier is associated with at least one aperiodic SRS resource set. Optionally, the power control parameters of different aperiodic SRS resource sets associated with the target identifier may be the same or different. For example, when the distance between the terminal and two TRPs is the same, the power control parameters of the aperiodic SRS resource sets corresponding to the two TRPs can be the same; when the distances from the terminal to the two TRPs are different, the non-periodic SRS resource sets corresponding to the two TRPs can be the same. The power control parameters of the periodic SRS resource set may be different.

In another embodiment, the above-mentioned control information may include indication information of a third indication field in the DCI, and the third indication field includes a sounding reference signal resource indicator (Sounding Reference Signal resource indicator, SRI) field, transmission precoding Matrix indication (Transmit Precoding Matrix Indicator, TPMI) field, redundancy version (Redundancy version) field, power control field, antenna port (Antenna ports) field, SRS request (request) field, and channel state information request (Channel State Information request), At least one item in the CSI request field. In other words, in this embodiment, the above-mentioned third indication field needs to be interpreted according to the corresponding configuration of the target identifier that triggers the corresponding uplink transmission.

It should be noted that at least one of the SRI domain, TPMI domain, redundancy version domain, power control domain, antenna port domain, SRS request domain, and CSI request domain of the M DCIs can be configured to different values. And each domain needs to be interpreted according to the corresponding configuration of the TRP identifier that triggers the corresponding uplink transmission. In other words, the parameters configured in at least one of the SRI domain, TPMI domain, redundancy version domain, power control domain, antenna port domain, SRS request domain, and CSI request domain of any two DCIs are different.

Optionally, before the receiving DCI, the method further includes:

Receive configuration information, where the configuration information is used to configure at least one aperiodic SRS resource set, and each target identifier is associated with at least one aperiodic SRS resource set.

The embodiments of the present invention can support multiple aperiodic SRS resource sets for codebook, non-codebook, beam management, and antenna switching scenarios. Among them, the above configuration information can configure at least one non-periodic SRS resource set for each TRP associated with a target identifier. Periodic SRS resource set. Optionally, in an embodiment, the set identifiers of the aperiodic SRS resource set associated with different target identifiers are different. That is to say, there is no intersection between the set identifiers of any two target identifiers associated with the aperiodic SRS resource set. For example, target identifier A is associated with aperiodic SRS resource set 1, and target identifier B is associated with aperiodic SRS resource set 2 and associated aperiodic SRS resource set 3.

Optionally, the target indication field of the DCI is used to activate a target aperiodic SRS resource set in the at least one aperiodic SRS resource set, and the target identifier associated with the target aperiodic SRS resource set is associated with the DCI The target identifiers are the same, and the target indication field is a field used to activate the aperiodic SRS resource set.

In other words, in the embodiment of the present invention, only when the target identifier associated with the aperiodic SRS resource set is consistent with the target identifier associated with the DCI used to activate the aperiodic SRS resource set, the target indication field in the DCI (for example, The SRS request field can be used to activate the aperiodic SRS resource set.

It should be noted that the method of obtaining the target identifier associated with the aperiodic SRS resource set can be set according to actual needs. For example, in one embodiment, the aperiodic SRS resource set includes a target identifier; in another embodiment, the aperiodic SRS resource set is obtained through the spatial relationship information (spatial relation info) of the RS associated in the aperiodic SRS resource set. Resource set associated target identifier.

Further, the method for determining the target identifier associated with the DCI may be set according to actual needs. For example, in an embodiment, the physical uplink sharing scheduled by the DCI is determined according to the target identifier associated with the DCI. The control information transmitted on the channel PUSCH also includes at least one of the following before:

Manner 1: Determine the target identifier associated with the DCI according to the control resource set group identifier (CORESET pool index) associated with the DCI;

Manner 2: Determine the target identifier associated with the DCI according to the first indication information carried by the DCI, where the first indication information is used to indicate the target identifier associated with the DCI;

Manner 3: Determine the target identifier associated with the DCI according to the second indication information carried by the DCI, where the second indication information is used to indicate a trigger state of activation;

Manner 4: Determine the target identifier associated with the DCI according to the sounding reference signal resource indication SRI carried by the DCI.

In the embodiment of the present invention, for the above method 1, it can be understood that the control resource set group identifier associated with the DCI indicates the target identifier associated with the DCI. In other words, the DCI only acts on the same target identifier. For example, in an embodiment, DCI is not configured with a control resource set group ID or DCI is configured with a control resource set group ID of 0, which means that the DCI is associated with a target ID of 1, and DCI is configured with a control resource set group ID of 1, which means that DCI associated target ID 2. In this embodiment, the target identifier includes only target identifier 1 and target identifier 2 as an example for description. In other embodiments, a larger number of target identifiers may be configured.

Regarding the above method 2, it can be understood that the target identifier is directly indicated in the DCI. Specifically, the position of the target identifier indicated in the DCI can be set according to actual needs. For example, in an embodiment, a separate indication field may be added for indication, or bits may be added to an existing indication field for indication.

In other words, in this embodiment, the first indication information is located in the first indication domain or the second indication domain of the DCI, and the first indication domain is an independent indication domain for indicating the target identifier, so The second indication field includes any of the following:

The field used to activate aperiodic SRS resource set (ie SRS request field);

SRI domain;

TPMI field, the TPMI field may include precoding information and number of layers (Precoding information and number of layers).

For example, in this embodiment, one bit may be added to the SRS request field, the SRI field, or the TPMI field to indicate the target identifier. Take the SRS request field to add 1 bit to indicate the target identifier as an example for description.

In this embodiment, the SRS request field is generally 2 bits, indicating 4 states: 00, 01, 10, and 11, where 00 indicates inactive, 01 indicates activated trigger state1, 10 indicates activated trigger state2, and 11 indicates activated trigger state3. In the case of adding 1 bit to indicate the target identifier, the first indication information can include two states of 0 and 1. When the first indication information is 0, it is used to indicate the target identifier 1; when the first indication information is 1, it is used to indicate Target ID 2.

At this time, the indication of the SRS request field can be understood as: 000 means that the target identification 1 is not activated, 001 means that the target identification 1 activates the trigger state 1, 010 means that the target identification 1 activates the trigger state 2, and 011 means that the target identification 1 activates the trigger state 3, 100 It means that the target identifier 2 is not activated, 101 means that the target identifier 2 activates the trigger state 1, 110 means that the target identifier 2 activates the trigger state 2, and 111 means that the target identifier 2 activates the trigger state 3.

Further, in a state where the target identifier is enabled, the DCI may carry the first indication information. The target identification enablement can be understood as multi-target identification enablement, that is, multi-TRP enablement. In other words, only when multiple TRPs are enabled, the DCI carries the first indication information.

For the above method 3, it should be noted that in the case of determining the target identifier associated with the DCI according to the second indication information carried by the DCI, it is agreed by the protocol, reported by the terminal, or configured by the network device for each trigger state and each target Identify the association relationship.

In this embodiment, the SRS request field is generally 2 bits, indicating 4 states: 00, 01, 10, and 11, where 00 indicates inactive, 01 indicates activated trigger state1, 10 indicates activated trigger state2, and 11 indicates activated trigger state3. The association relationship that can be agreed by the protocol, reported by the terminal, or configured by the network device without adding bits may include: trigger state1 is associated with target identifier 1, and trigger state2 and trigger state3 are associated with target identifier 2.

Further, in order to obtain more trigger state, the trigger state can be set to 3 bits. The indication of the SRS request field can be understood as: 000 means inactive, 001 means trigger state1, 010 means trigger state2, 011 means trigger state3, 100 means trigger state4, 101 means trigger state5, 110 means trigger state6, 111 indicates that trigger state7 is activated. The foregoing association relationship may include: trigger state1, trigger state2, and trigger state3 are associated with target identifier 1, and trigger state4, trigger state5, trigger state6, and trigger state7 are associated with target identifier 2. Of course, in other embodiments, other association groups can also be used. For example, trigger states 1 to 7 are associated with three target IDs, or target ID 1 is associated with two trigger states, and target ID 2 is associated with 5 trigger states. I will not list them all here.

For the above method 4, it should be noted that in the case of determining the target identifier associated with the DCI according to the sounding reference signal resource indication SRI carried by the DCI, if the PUSCH transmission is a codebook-based transmission, each An aperiodic SRS resource set is associated with one SRS resource.

In this embodiment, for codebook transmission, in the case of multiple TRPs, only one SRS resource is supported in the SRS resource set. Each target ID allows to configure at most one SRS resource set. The SRS resource set associated with different target IDs is different in the associated SRS resource set. Among them, SRI is used to indicate SRS resource set.

It should be understood that when at least two of the ways 1 to 4 are used for joint indication, each way indicates that the target identifier associated with the same DCI should be the same.

Further, the method further includes:

Receive target information, where the target information is used to configure or indicate enable information, and the enable information includes target identification enabling or target identification disabling.

In this embodiment, target identification enabling or disabling can be understood as multi-TRP enabling or disabling. When the target identifier is enabled, the terminal can send PUSCH to at least two TRPs at the same time or time-sharing. When the target identifier is enabled, the terminal can only send PUSCH to one TRP. Specifically, the target information may be received before the DCI is received, and the enabling information may be configured or instructed. Optionally, the network equipment can instruct the UE whether multiple TRPs are enabled or disabled through Medium Access Control Control Element (MAC CE) and/or Radio Resource Control (RRC) signaling .

In an embodiment, the enabling can be individually activated or deactivated. In another embodiment, TRP can be configured through RRC, and enabled through MAC CE activation or deactivation. RRC configuration includes configuring multiple TRP numbers and so on. Among them, deactivation and enablement can be understood as deactivation.

In order to better understand the present invention, the implementation of the present invention will be described in detail below through specific examples.

For each of the codebook, non-codebook, beam management, and antenna switching scenarios, multiple aperiodic SRS resource sets can be supported, and each target identifier (such as TRP identifier or associated information) is used as an example. Explain) Correspond to at least one aperiodic SRS resource set. The power control parameters of the two aperiodic SRS resource sets may be different.

Optionally, the method for obtaining the TRP identifier associated with the aperiodic SRS resource set may be the TRP identifier included in the aperiodic SRS resource set or the spatial relation info of the RS associated in the aperiodic SRS resource set.

The following method 1 to method 6 can be used to determine the TRP identifier associated with the DCI.

Method 1: Obtain the TRP ID by controlling the resource set group ID.

Optionally, the associated TRP identifier of the DCI is indicated by the control resource set group identifier associated with the DCI. That is, the DCI only acts on the same TRP identifier. That is, if the control resource set group identifier is not configured or the control resource set group identifier is equal to 0, it means that the DCI is associated with TRP identifier 1, and the control resource set group identifier is equal to 1 that means the DCI is associated with TRP identifier 2.

Method 2: DCI directly carries TRP ID field.

Method 3: Add 1 bit to the field used to activate the aperiodic SRS resource set, SRI field, or TPMI field in the DCI to indicate the associated TRP identifier.

Method 4: The domain used to activate the aperiodic SRS resource set, SRI domain, or TPMI domain in the DCI only when multiple TRPs are enabled, add 1 bit to indicate the associated TRP identifier.

Method 5: Indirectly obtain the TRP identifier associated with DCI through the trigger state.

When DCI cannot directly obtain the associated TRP identifier, the trigger state is grouped, and the trigger states in the group are associated with the same TRP identifier, the grouping method protocol is agreed, the terminal reports, or the network is configured through MAC CE or RRC. Among them, the trigger state between groups cannot be the same.

Optionally, in an embodiment, without increasing the trigger state, the SRS request field is generally 2 bits, indicating 4 states: 00, 01, 10, and 11, where 00 means inactive, and 01 means trigger state1 is activated. 10 means trigger state2 is activated, and 11 means trigger state3 is activated. Among them, trigger state1 is associated with target identification 1, and trigger state2 and trigger state3 are associated with target identification 2. That is to say: 00 indicates not activated; 01 indicates associated target identification 1 and trigger state 1 is activated; 10 indicates associated target identification 2 and activates trigger state 2; 11 indicates associated target identification 2 and activates trigger state 3.

Optionally, in another embodiment, the number of trigger states is increased, and the SRS request field overhead is also increased accordingly. At this time, the SRS request field is 3 bits, indicating 8 states, among which 000 means inactive, 001 means trigger state1, 010 means trigger state2, 011 means trigger state3, 100 means trigger state4, 101 means trigger state5 , 110 means trigger state6 is activated, 111 means trigger state7 is activated. Optionally, trigger state1, trigger state2, and trigger state3 may be associated with target identifier 1, and trigger state4, trigger state5, trigger state6, and trigger state7 may be associated with target identifier 2.

Method 6: Obtain the TRP identifier associated with DCI through SRI.

Optionally, for codebook transmission, in the case of multiple TRPs, only one SRS resource can be associated in the aperiodic SRS resource set. Each TPR identifier allows configuration of at most one aperiodic SRS resource set. The associated SRS receipt ID in the SRS receipt set associated with different TRP identifiers is different.

Among them, SRI is used to indicate aperiodic SRS resource set.

It should be noted that the network equipment can indicate whether to enable or disable multiple TRPs on the network side of the UE through MAC CE and/or RRC signaling. For example, it may include individual activation enable or deactivation enable, or through RRC configuration, and MAC CE activation or deactivation enable. Among them, RRC configuration includes configuring multiple TRP numbers and so on.

Optionally, for the above methods 1 to 6, at least one of the SRI domain, TPMI domain, redundancy version domain, power control domain, antenna port domain, SRS request domain, and CSI request domain of multiple DCIs can be configured Into different values. And each domain needs to be interpreted according to the corresponding configuration of the TRP identifier that triggers the corresponding uplink transmission.

In this embodiment, only when the target identifier associated with the aperiodic SRS resource set is consistent with the target identifier associated with the DCI used to activate the aperiodic SRS resource set, the target indication field (for example, the SRS request field) in the DCI can be used for Activate the aperiodic SRS resource set.

It should be noted that when the network device does not enable multiple TRPs, the UE performs demodulation according to the normal DCI size (size). If the network equipment is enabled, the UE performs demodulation according to the DCI size of multiple TRPs.

The following describes how to increase the number of aperiodic SRS resource sets.
