1. A method performed by a user equipment (UE) for monitoring a tracking reference signal (TRS), the method comprising:
receiving, from a base station (BS), a TRS configuration that indicates one or more TRS resource sets for the UE to monitor the TRS;
determining whether a Layer 1 (L1)-based availability indication configured for the one or more TRS resource sets is received from the BS, wherein the L1-based availability indication comprises a TRS availability indication that is included in a downlink control information (DCI) format 1_0 received, from the BS, with a cyclic redundancy check (CRC) scrambled by a Paging-Radio Network Temporary Identifier (P-RNTI); and
determining that the one or more TRS resource sets are unavailable in response to determining that the L1-based availability indication has not been received from the BS.
