Dynamic indication of tracking reference signal

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

• at least one processor;
• and
• at least one memory coupled to the at least one processor, the at least one memory storing instructions executable by the at least one processor to cause the UE to:
• receive one or more tracking reference signal parameters configured for the UE to perform channel measurements associated with one or more tracking reference signals received by the UE operating in a first operation mode;
• receive an indication that at least one tracking reference signal parameter of the one or more tracking reference signal parameters is configured as a dynamic tracking reference signal parameter;
• receive the one or more tracking reference signals;
• and
• transmit, responsive to the indication of the dynamic tracking reference signal parameter, a channel measurement report including channel measurements that are based at least in part on a set of updated tracking reference signal parameters comprising at least the dynamic tracking reference signal parameter.

An apparatus for wireless communication at a network entity, comprising:

• at least one processor;
• and
• at least one memory coupled to the at least one processor, the at least one memory storing instructions executable by the at least one processor to cause the network entity to:
• transmit one or more tracking reference signal parameters configured for a user equipment (UE) to perform channel measurements associated with one or more tracking reference signals transmitted to the UE;
• transmit a dynamic paging indicator message that indicates a set of updated tracking reference signal parameters comprising at least one tracking reference signal parameter that is different from the one or more tracking reference signal parameters;
• transmit the one or more tracking reference signals;
• and
• receive, responsive to the dynamic paging indicator message, a channel measurement report including channel measurements that are in accordance with the set of updated tracking reference signal parameters.
