Classification: CPC H | IPC H

Claim 0:
1. A method for reporting channel state information (CSI) by user equipment (UE) for beamforming based on an antenna array in a wireless communication system, the method comprising:
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,
wherein 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.
