16. A method for wireless communication at a first transmission-reception point, comprising:
identifying a set of transmission-reception points that transmit joint communications to at least a first user equipment (UE), wherein each transmission-reception point of the set of transmission-reception points has a separate cell identification;
identifying a subset of the set of transmission-reception points that are to transmit periodic tracking reference signals, wherein the subset of transmission-reception points is a first subset of transmission-reception points, and wherein a second subset of the set of transmission-reception points transmits one or more aperiodic tracking reference signals or periodic tracking reference signals, and wherein the second subset of transmission-reception points is non-overlapping with the first subset of transmission-reception points; and
transmitting, based at least in part on the identifying, configuration information to at least the first UE that indicates the subset of transmission-reception points that are to transmit the periodic tracking reference signals.
