Abstract
The disclosure relates to a 5G or pre-5G communication system for supporting higher data transmission rates than 4G communication systems such as LTE systems. According to an embodiment, a method performed by a base station supporting beam training using a beamforming codebook may comprise storing a plurality of codebooks corresponding to a plurality of different beamwidths, receiving a beam adjustment request from a user equipment (UE), determining, among the plurality of codebook, a codebook including beam codebooks for beam coverages including a beamwidth corresponding to a channel state of the UE, in response to receiving the beam adjustment request, and transmitting, to the UE, signals that are beamformed based on the codebook through a plurality of transmission beams using digital beamforming matrixes of the codebook.
