Abstract
A method of establishing synchronization with a base station by a mobile station in a communication system using beamforming includes: receiving a downlink signal transmitted through at least one transmission beam by using at least one reception beam; determining at least one of a propagation delay and a signal strength of the received downlink signal for each downlink transmission/reception beam pair through which the downlink signal is transmitted/received, wherein each downlink transmission/reception beam pair includes a transmission beam through which the downlink signal is transmitted from the base station and a reception beam through which the downlink signal is received by the mobile station; and establishing a downlink frame boundary of the mobile station by using the determined at least one of the propagation delay and the signal strength for each downlink transmission/reception beam pair.
