1. An apparatus for wireless communications at a user equipment (UE), comprising:
a memory comprising instructions; and
one or more processors configured, individually or in any combination, to execute the instructions and cause the apparatus to:
receive signaling configuring the UE with at least a first sounding reference signal (SRS) resource set and a second SRS resource set;
receive a first downlink control information (DCI) that schedules a first physical uplink shared channel (PUSCH) and indicates a first sounding reference signal (SRS) resource indicator (SRI) value;
receive a second DCI that schedules a second PUSCH and indicates a second SRI value; and
determine SRS resources indicated by the first SRI value and the second SRI value, based on an association between control resource set (CORESET) pool index values for CORESETs in which the first DCI and the second DCI are received and identifiers (IDs) of the first SRS resource set and the second SRS resource set, wherein according to the association:
whichever of the first or second SRS resource set has a lower ID is associated with a first CORESET pool index value; and
whichever of the first or second SRS resource set has a higher ID is associated with a second CORESET pool index value.
