Abstract: Disclosed in the present invention is a method for a user equipment reporting channel state information to a base station in a wireless communication system. The method for reporting CSI comprises the steps of: receiving, from the base station, a channel state information-reference signal (CSI-RS) defined by at least two antenna ports; estimating the rank of a downlink channel based on the CSI-RS; configuring a plurality of precoders corresponding to the estimated rank with at least two precoder groups; calculating a channel quality indicator under the assumption that the at least two precoder groups are rotationally applied to at least one resource block unit, wherein precoders included in the precoder groups rotationally applied to the at least one resource block unit is rotationally applied to at least one resource element unit; and reporting the CSI including the calculated CQI to the base station.

Abstract: The present disclosure provides a method for reporting CSI in a wireless communication system. In the present disclosure, a method for reporting channel state information (CSI) in a wireless communication system, which is performed by a UE includes: receiving, from an eNB, downlink control information (DCI) indicating activation of semi-persistent (SP) CSI reporting, in which the downlink control information is scrambled with a specific RNTI distinguished from a Cell-Radio Network Temporary Identity (C-RNTI); and reporting, to the eNB, the semi-persistent CSI through a physical uplink shared channel (PUSCH) based on the received downlink control information.
