Abstract

Claims (32)

1 . A user equipment (UE) for wireless communication, comprising:

at least one memory; and

at least one processor coupled to the at least one memory, wherein the at least one processor is configured to:

receive first control signaling indicating a first sounding reference signal (SRS) resource set and a second SRS resource set;

receive second control signaling indicating a first SRS indicator without a second SRS indicator and indicating a first precoding and number of layers field without a second precoding and number of layers field; and

transmit one or more uplink transmissions on a physical uplink shared channel using the first SRS resource set based on the second control signaling.

2 . The UE of claim 1 , the one or more uplink transmissions are associated with a Type 1 configured grant.

3 . The UE of claim 1 , wherein the second control signaling indicates one or more of a pathloss reference index field, a p0-PUSCH-Alpha field, or a powerControlLoopToUse field.

4 . The UE of claim 1 , wherein one or both of the first control signaling or the second control signaling comprise radio resource control signaling.

5 . The UE of claim 1 , wherein, to receive the second control signaling, the one or more processors are configured to execute the code to cause the UE to:

receive second control signaling indicating a configured grant physical uplink shared channel configuration.

6 . The UE of claim 1 , wherein the one or more uplink transmissions comprise codebook physical uplink shared channel transmissions or non-codebook physical uplink shared channel transmissions.

7 . A user equipment (UE) for wireless communication, comprising:

at least one memory; and

at least one processor coupled to the at least one memory, wherein the at least one processor is configured to:

receive first control signaling indicating a first sounding reference signal resource (SRS) set and a second SRS resource set;

receive second control signaling indicating a first SRS resource indicator field and a second SRS resource indicator field and indicating a first precoding and number of layers field and a second precoding and number of layers field; and

transmit one or more codebook physical uplink shared channel transmissions on a physical uplink shared channel using the first SRS resource set or the second SRS resource set, wherein the first SRS resource indicator field is associated with the first SRS resource set and the second SRS resource indicator field is associated with the second SRS resource set.

8 . The UE of claim 7 , wherein the second control signaling indicates a first p0-PUSCH-Alpha field and a second p0-PUSCH-Alpha field.

9 . The UE of claim 7 , wherein using the first SRS resource set or the second SRS resource set is based on a fixed order for the one or more codebook physical uplink shared channel transmissions.

10 . The UE of claim 9 , wherein using the first SRS resource set or the second SRS resource set is based on a fixed order for the one or more codebook physical uplink shared channel transmissions comprises using the first SRS resource set for a first codebook physical uplink shared channel transmission in time of the one or more codebook physical uplink shared channel transmissions and using the second SRS resource set for one or more second codebook physical uplink shared channel transmissions in time of the one or more codebook physical uplink shared channel transmissions based on a mapping type.

11 . The UE of claim 10 , wherein the mapping type comprises a cyclic mapping of the first SRS resource set and the second SRS resource set.

12 . The UE of claim 10 , wherein the mapping type comprises a sequential mapping of the first SRS resource set and the second SRS resource set.

13 . The UE of claim 7 , wherein the one or more codebook physical uplink shared channel transmissions are associated with a Type 1 configured grant.

14 . The UE of claim 7 , wherein the second control signaling indicates a pathloss reference index field, a powerControlLoopToUse field, sounding reference signal resource indicator field, a precoding and number of layers field or a combination thereof.

15 . The UE of claim 7 , wherein one or both of the first control signaling or the second control signaling comprises radio resource control signaling.

16 . The UE of claim 7 , wherein, to receive the second control signaling, the one or more processors are configured to execute the code to cause the UE to:

receive second control signaling indicating a configured grant physical uplink shared channel configuration.

17 . A method of wireless communication performed by a user equipment (UE), comprising:

receiving first control signaling indicating a first sounding reference signal (SRS) resource set and a second SRS resource set;

receiving second control signaling indicating a first SRS resource indicator without a second SRS resource indicator and indicating a first precoding and number of layers field without a second precoding and number of layers field; and

transmitting one or more uplink transmissions on a physical uplink shared channel using the first SRS resource set based on the second control signaling.
