An approach to providing an indication of the availability of tracking reference signal (TRS) and/or channel state information reference signal (CSI-RS) occasions. Channels for carrying the indication include system information block (SIB) signaling, paging physical downlink control channel (PDCCH), and paging early indications. Various approaches are described that provide the information, including a number of bitmap approaches, a hierarchical informational approach, a dynamic signal indication that carries configuration indices. Additional approaches are described that reduce unnecessary overhead by specifying certain reference signal (RS) occasions as being available.
