1. A communication method of a base station (BS) in a beamforming-based wireless communication system supporting a plurality of frequency bands, the communication method comprising:
transmitting each of synchronization signal blocks (SSBs) including first information about a BS installed at a co-location through a plurality of first transmission beams having different directions in a first frequency band; and
performing, using a transmission beam in a second frequency band, communication with a user equipment (UE) for which an optimal transmission/reception beam pair in the second frequency band having a higher frequency than the first frequency band is determined based on the first information.
