Fast adaptation of transmission properties of SRS resource sets

A method for wireless communication by a user equipment (UE), comprising:

• receiving sounding reference signal (SRS) configuration information, configuring the UE with one or more SRS resource sets, wherein each of the one or more SRS resource sets comprises a plurality of SRS resources;
• receiving signaling comprising a media access control-control element (MAC CE) including an indication of one or more updated parameters for a specific SRS resource set in the one or more SRS resource sets, wherein the one or more updated parameters comprise
• an updated identifier (ID) of a channel state information reference signal (CSI-RS) for the specific SRS resource set of the one or more SRS resource sets;
• updating the ID of the CSI-RS associated with the specific SRS resource set without updating other SRS resource set parameters;
• and
• transmitting one or more SRSs according to the one or more updated parameters.

A method for wireless communication by a base station (BS), comprising:

• transmitting sounding reference signal (SRS) configuration information to a user equipment (UE), configuring the UE with one or more SRS resource sets, wherein each of the one or more SRS resource sets comprises a plurality of SRS resources;
• transmitting signaling to the UE comprising a media access control-control element (MAC CE) including:
• a field that indicates which SRS resources of the plurality of SRS resources in the one or more SRS resource sets are active and which SRS resources of the plurality SRS resources in the one or more SRS resources sets are inactive;
• an indication of an updated identifier (ID) of a channel state information reference signal (CSI-RS) associated with a specific SRS resource set of the one or more SRS resource sets;
• the indication of the updated ID is configured to cause the UE to update the ID of the CSI-RS associated with the specific SRS resource set without updating other SRS resource set parameters;
• and
• receiving one or more SRSs from the UE on SRS resources of the plurality of SRS resources that are indicated as active.
