Abstract
A method for reporting channel state information (CSI) by user equipment (UE) for beamforming based on an antenna array in a wireless communication system according to an embodiment of the present disclosure includes: receiving a channel state information reference signal (CSI-RS); generating channel state information using the CSI-RS and a codebook generated in advance; and reporting the channel state information. The channel state information includes information related to a codevector determined in the codebook, the antenna array has a three-dimensional shape having omnidirectional symmetry, the codebook is generated based on a position of the UE having a center of the three-dimensional shape as an origin, and the position of the UE is represented based on a polar coordinate system.
