Abstract
(EN)
A method for reporting channel state information (CSI) by means of a terminal in a wireless communication system, according to one embodiment of the present invention, comprises the steps of: receiving a channel state information reference signal (CSI-RS) from a base station, wherein the CSI-RS is related to at least one panel of an antenna array of the base station; generating CSI on the basis of the CSI-RS and a codebook according to a specific shape of the at least one panel; and reporting the CSI to the base station.
