Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configured grant (CG) physical uplink shared channel (PUSCH) configuration comprising at least one sounding reference signal (SRS) resource indicator, associated with at least one set of PUSCH repetitions, that indicates at least one SRS resource corresponding to at least one SRS resource set, wherein the at least one SRS resource set is listed in at least one of a first or a second SRS resource set list, wherein at least one SRS resource set listed in the second SRS resource set list is a subset of a corresponding SRS resource set listed in the first SRS resource set list. The UE may determine at least one set of PUSCH transmission parameters based at least in part on a determination of the at least one SRS resource set. Numerous other aspects are provided.

Dependent claims

An apparatus for wireless communication, comprising:

at least one processor;
and
at least one memory coupled with the at least one processor, wherein the at least one processor is configured to cause the apparatus to:
receive a sounding reference signal (SRS) configuration that indicates:
a respective single SRS resource set in each SRS resource set list of one or more SRS resource set lists, or
a respective plurality of SRS resource sets in each SRS resource set list of the one or more SRS resource set lists;
receive a configured grant (CG) physical uplink shared channel (PUSCH) configuration comprising at least one SRS resource indicator associated with at least one set of PUSCH repetitions, wherein:
the at least one SRS resource indicator includes only one SRS resource indicator when the SRS configuration indicates the respective single SRS resource set in each SRS resource set list of the one or more SRS resource set lists,
the at least one SRS resource indicator includes a first SRS resource indicator and a second SRS resource indicator when the SRS configuration indicates the respective plurality of SRS resource sets in each SRS resource set list of the one or more SRS resource set lists,
the at least one SRS resource indicator indicates at least one SRS resource corresponding to at least one SRS resource set,
the at least one SRS resource set is listed in at least one of a first SRS resource set list of the one or more SRS resource set lists or a second SRS resource set list of the one or more SRS resource set lists,
at least one SRS resource set listed in the second SRS resource set list is a subset of a corresponding SRS resource set listed in the first SRS resource set list, and
the at least one set of PUSCH repetitions comprises a first set of PUSCH repetitions associated with a first SRS resource set and a second set of PUSCH repetitions associated with a second SRS resource set;
and
transmit the at least one set of PUSCH repetitions based at least in part on at least one set of PUSCH transmission parameters, the at least one set of PUSCH transmission parameters being based at least in part on the at least one SRS resource set.
