1. A method of reporting, by user equipment (UE), channel state information (CSI) in a wireless communication system, the method comprising:
receiving a CSI-related reference signal;
measuring the CSI based on the reference signal and a codebook; and
reporting the CSI,
wherein reception and transmission operations of the UE are performed based on a three-dimensionally shaped antenna array formed by arranging a plurality of antenna elements in a three-dimensional configuration, and
wherein the codebook is generated based on a path difference between a distance from an origin, which is a center of the three-dimensional shape, to the UE and a distance from a specific antenna element to the UE.
