Abstract
Certain aspects of the present disclosure provide techniques for triggering aperiodic sounding reference signal (A-SRS) transmission across multiple uplink component carriers.
Claims30
A method for wireless communications by a user equipment, comprising:
- receiving a sounding reference signals (SRS) configuration indicating a plurality of SRS resource sets;
- receiving signaling triggering aperiodic SRS (A-SRS) of at least one SRS resource set on at least two different uplink component carriers (CCs);
- and
- transmitting A-SRS of the SRS resource sets on the different uplink CCs, wherein at least one of the uplink CCs is configured for at least one of physical uplink shared channel (PUSCH) or physical uplink control channel (PUCCH) transmission.

A method for wireless communications by a network entity, comprising:
- sending, to a user equipment (UE), a sounding reference signals (SRS) configuration indicating a plurality of SRS resource sets;
- sending the UE signaling triggering aperiodic SRS (A-SRS) of at least one SRS resource set on at least two different uplink component carriers (CCs);
- and
- monitoring for A-SRS of the SRS resource sets transmitted on the different uplink CCs, wherein at least one of the uplink CCs is configured for at least one of physical uplink shared channel (PUSCH) or physical uplink control channel (PUCCH) transmission.
