A method of operating a terminal is provided. The method includes: selecting a first pattern as a pattern of a reception beam; searching for cells in the wireless communication system using the reception beam of the first pattern; determining a first candidate group including at least one candidate for a beam pattern pair with the first pattern of the reception beam, wherein each of the at least one candidate corresponds to a transmission beam pattern and a cell; determining whether to decode a physical broadcast channel received from a first candidate of the first candidate group; decoding the PBCH based on the determining; and selecting one of the transmission beam patterns for the beam pattern pair with the first pattern of the reception beam from the first candidate group based on the decoding.
