Abstract

The present disclosure relates to a communication method and device in a beamforming-based wireless communication system supporting a plurality of frequency bands, the communication method for a terminal, according to an embodiment of the present disclosure, comprising the steps of: performing a beam search using a plurality of first reception beams in a first frequency band and receiving a synchronization signal block (SSB) comprising first information about a base station provided at the same location; performing, on the basis of the first information, a beam search for a plurality of second reception beams in a second frequency band belonging to a subset of the first reception beams that received the SSB in the first frequency band; and communicating with the base station in the second frequency band by selecting an optimal pair of transmission and reception beams as result of the beam search for the plurality of second reception beams.
