Classification: CPC H  Y | IPC H

Claim 13:
14. A base station for transmitting a signal in a wireless communication system, the base station comprising:
a transceiver; and
a processor configured to control the transceiver to:
transmit, through higher layer signaling, a configuration for a tracking reference signal (TRS) for a terminal in a radio resource control (RRC) idle mode or an RRC inactive mode;
generate downlink control information (DCI) including availability indication information of the TRS;
transmit, to the terminal in the RRC idle mode or the RRC inactive mode based on a paging-radio network temporary identifier (P-RNTI), a physical downlink control channel (PDCCH) including the DCI; and
transmit the TRS to the terminal in the RRC idle mode or the RRC inactive mode, based on the availability indication information of the TRS and the configuration for the TRS,
wherein the configuration for the TRS includes a periodicity and a slot offset of the TRS,
wherein the configuration includes information for a plurality of TRS resource sets each having a plurality of TRS resources,
wherein each of the plurality of TRS resource sets is allocated with an identifier (ID) to be used for the availability indication information,
wherein, for the plurality of TRS resource sets, the availability indication information indicates availability per each ID and
wherein the availability indication information includes a plurality of bits associated with a plurality IDs of the plurality of TRS resource sets.
