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