Abstract:
Disclosed are a method for transmitting/receiving channel state information in a wireless communication system and an apparatus for the same. Particularly, a method for reporting channel state information (CSI) by a user equipment (UE) in a wireless communication system may comprise the steps of: receiving channel state information reference signal (CSI-RS) from a base station through a multi-antenna port; and reporting CSI to the base station, wherein the CSI includes selection information indicating multiple codewords used to generate a precoding matrix within a codebook for reporting the CSI, a power coefficient and a phase coefficient are applied to each of the multiple codewords and the precoding matrix is then generated on the basis of a linear combination of the multiple codewords to each of which the power and phase coefficients are applied, and the selection information and information indicating the power coefficient are transmitted at different CSI reporting instances.

Claim (Index 29):
A user equipment (UE) for reporting Channel State Information (CSI) in a wireless communication system, the UE comprising:\n a radio frequency (RF) unit for transmitting and receiving a radio signal; and a processor for controlling the RF unit, wherein the processor is configured to: receiving a Channel State Information Reference Signal (CSI-RS) through multiple antenna ports from a base station (BS) through the RF unit; and reporting the CSI to the BS through the RF unit, wherein the CSI includes selection information indicating a plurality of codewords used for generating a precoding matrix in a codebook for reporting the CSI, wherein, after a power coefficient and a phase coefficient are applied to each of the plurality of codewords, the precoding matrix is generated based on a linear combination of the plurality of codewords to which the power coefficient and the phase coefficient are applied, and wherein the selection information includes information encoded by a combination formula.
