Sounding reference signal triggering techniques

A method for wireless communications by a network entity, comprising:

• transmitting, to at least one user equipment (UE), a downlink control information (DCI) with at least one block configured to trigger aperiodic sounding reference signal (SRS) transmission from the UE on at least one SRS resource set;
• deciding whether to include a transmit power control (TPC) command in the DCI for the at least one SRS resource set based on one or more conditions;
• and
• processing A-SRS transmitted in accordance with the DCI.

An apparatus for wireless communications by a user equipment (UE), comprising:

• means for receiving a downlink control information (DCI) with at least one block configured to trigger aperiodic sounding reference signal (SRS) transmission from the UE on at least one SRS resource set;
• means for determining a transmit power control (TPC) command to apply to the A-SRS if the DCI lacks a TPC command for the at least one SRS set;
• and
• means for transmitting the A-SRS in accordance with the DCI and the determined TPC command.

• a receiver configured to receiving a downlink control information (DCI) with at least one block configured to trigger aperiodic sounding reference signal (SRS) transmission from the UE on at least one SRS resource set;
• at least one processor configured to determine a transmit power control (TPC) command to apply to the A-SRS if the DCI lacks a TPC command for the at least one SRS set;
• and
• a transmitter configured to transmit the A-SRS in accordance with the DCI and the determined TPC command.
