Abstract: An operating method of a user equipment in a wireless communication system includes dividing a first frequency band, from among a plurality of frequency bands, into a plurality of sub-bands, based on a first radio frequency technology (RAT), measuring peak powers of each sub-band of the plurality of sub-bands, determining at least one effective sub-band from among the plurality of sub-bands, based on the measured peak powers, detecting, based on the determining of the at least one effective sub-band, a first effective signal through a frequency search operation using a correlation component of a synchronization signal corresponding to at least one of the first frequency band and the at least one effective sub-band, and performing initial access to a cell, based on the detecting the first effective signal.

Abstract: Provided is a method of operating a wireless communication device for performing a cell search, the method including generating a first accumulated signal by accumulating a downlink signal by a first reference number of times, the generating of the first accumulated signal being based on an interval of a first synchronization signal included in the downlink signal, calculating a first quality metric based on the first accumulated signal, determining whether the first quality metric exceeds a first threshold value, and updating the first accumulated signal in response to determining the first quality metric does not exceed the first threshold value to obtain an updated first accumulated signal.
