Abstract: Disclosed in the present invention is a method by which a terminal reports channel status information (CSI) to a base station in a wireless communication system. The method comprises the steps of: receiving, through an upper layer, information on one CSI process having a first enhanced multiple input multiple output (eMIMO) type and a second eMIMO type; receiving a first channel status information-reference signal (CSI-RS) corresponding to the first eMIMO type; periodically reporting, to the base station, first CSI measured on the basis of the first CSI-RS; receiving a second CSI-RS, which corresponds to the second eMIMO type, beamformed on the basis of the first CSI; and periodically reporting, to the base station, second CSI measured on the basis of the second CSI-RS, wherein a priority of the first CSI is set to be equal to a priority of a CSI-RS resource indicator (CRI).

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.

Abstract: Disclosed in the present application is a method for a terminal periodically reporting, to a base station, channel state information on the basis of a linear combination codebook in a wireless communication system. Particularly, the method comprises the steps of: receiving a reference signal from the base station; and reporting channel state information which has been outputted to the base station on the basis of the reference signal, wherein the channel state information includes a channel quality indicator and information relating to a precoding matrix index, and when a rank outputted on the basis of the reference signal is 2, the precoding matrix index is selected from a codebook which has been sub-sampled, wherein a precoding matrix constituting the sub-sampled codebook comprises a first column vector for a first layer and a second column vector for a second layer that crosses the first column vector, wherein the information relating to the precoding matrix index indicates three co-phase coefficients defining the first column vector as a 4-bit size, and wherein three co-phase coefficients defining the second column vector are identical to the three co-phase coefficients defining the first column vector.
