1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
determining a transmission frequency band of a reference signal based on an initial frequency band for an initial access procedure, a control resource set (CORESET) configured for the UE using a master information block (MIB), and a CORESET associated with a paging search space set for monitoring a paging message, wherein the reference signal is received by the UE in an IDLE state or an INACTIVE state;
receiving, from a base station (BS), the reference signal based on the transmission frequency band of the reference signal;
performing time synchronization and frequency synchronization with the BS based on the reference signal; and
receiving, from the BS, the paging message including an identifier of the UE based on the time synchronization and frequency synchronization.
