Abstract: Provided is a communication system for supporting higher data rates. A method by which a user equipment selects a beam for transceiving data to or from a base station in an initial access mode is provided. The method includes determining a first receive-beam-parameter including information about the number of receive antennas to be used for first beam searching, receiving, from the BS, a first transmit-beam-parameter including information about the number of transmit antennas to be used for the first beam searching, receiving first RS identified based on the first transmit-beam-parameter while changing a receive beam based on the first receive-beam-parameter, selecting a transmit beam and a receive beam to be used for data transmission and reception, based on the received first RS, and transmitting information about the transmit beam to the BS.
