A method of a user equipment (UE) in a wireless communication system is provided. The method comprises: receiving, from a base station (BS), a set of radio resource control (RRC) parameters comprising at least one measurement object (MO); identifying, based on the at least one MO, at least one modulo value for synchronization signals and physical broadcast channel (SS/PBCH) blocks, and at least one bitmap indicating indices of the SS/PBCH blocks; identifying a set of SS/PBCH block locations based on the at least one modulo value and the at least one bitmap; performing radio resource management (RRM) measurement based on the identified set of SS/PBCH block locations; and transmitting, to the BS via an uplink channel, a measurement report message including a result of the RRM measurement.
