Abstract: Disclosed is a method for a terminal reporting aperiodic channel status information (CSI) to a base station in a wireless communication system. The method comprises the steps of: receiving, from a base station via downlink control information (DCI), a CSI report triggering message of at least one CSI process, among multiple CSI processes, that is connected with one enhanced multiple input multiple output (eMIMO) type among a first eMIMO type and a second eMIMO type; and updating an aperiodic CSI associated with the at least one CSI process and reporting same to the base station based on a reference signal corresponding to the one eMIMO type.

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.

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: A channel measurement method in a wireless communication system and an apparatus therefor are disclosed. Specifically, a method for measuring a channel by a terminal in the wireless communication system may comprise the steps of: receiving, from a base station, a reference signal on part of antenna ports within a two-dimensional antenna port array; measuring channels for the part of antenna ports on the basis of the reference signal received from the base station; and reconstructing a channel for an antenna port which is not used for transmission of the reference signal within the two-dimensional antenna port array, using the channel measurement result, to reconstruct channels for all antenna ports within the two-dimensional antenna port array.
