13. A user equipment (UE) in a wireless communication system, the UE comprising:
at least one transceiver;
at least one processor; and
at least one memory operably connected to the at least one processor and configured to store instructions that, when executed, cause the at least one processor to perform operations comprising:
receiving a synchronization signal/physical broadcast channel (SS/PBCH) block in symbols in a specific slot through the at least one transceiver;
determining an index of the SS/PBCH block based on a modulo operation for an index of a demodulation reference signal (DMRS) sequence in a PBCH and Q value, wherein the Q value indicates quasi co-location (QCL) relation between SS/PBCH block positions,
establishing a connection with a base station (BS) based on the SS/PBCH block;
after the establishing the connection, monitoring a physical downlink control channel (PDCCH) during on duration based on a configured DRX operation; and
starting an inactivity timer and staying awake based on the successfully received PDCCH during the on duration.
