Path-loss estimation using path-loss reference signal activation and deactivation

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

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive, from a network entity, a configuration for a plurality of reference signals for path-loss estimation;
• receive, from the network entity, a medium access control-control element (MAC-CE) updating a reference signal from the plurality of reference signals to use for the path-loss estimation;
• update the reference signal in response to receiving the MAC-CE, wherein the instructions to update the reference signal are executable by the processor to cause the apparatus to activate the reference signal from the plurality of reference signals to use for the path-loss estimation;
• perform layer 3 filtering on a plurality of measurements for the path-loss estimation, wherein the instructions to perform the layer 3 filtering is based at least in part on activating the reference signal;
• and
• transmit an uplink message according to an uplink transmit power based at least in part on the layer 3 filtering.
