Abstract: A method of receiving a downlink channel, which is received by a user equipment from an eNB in a wireless communication system, is disclosed in the present specification. Specifically, the method includes the steps of receiving a downlink control channel for receiving a DM-RS (demodulation reference signal) based downlink data channel from the eNB, and receiving the DM-RS based downlink data channel using DM-RS configuration information included in the downlink control channel. In this case, if single-codeword transmission via the DM-RS based downlink data channel is indicated by the downlink control channel, the DM-RS based downlink data channel is received using a transmission diversity scheme. If two-codewords transmission via the DM-RS based downlink data channel is indicated by the downlink control channel, the DM-RS based downlink data channel is received using a spatial multiplexing scheme.

Abstract: Disclosed in the present application is a method by which a terminal reports aperiodic channel status information (CSI) to a base station in a wireless communication system. Particularly, the method comprises the steps of: receiving, from the base station, through downlink control information (DCI), a CSI report triggering message including information on at least one CSI process among a plurality of CSI processes and on one aperiodic reference signal among a plurality of aperiodic reference signal resources included in the at least one CSI process; and updating the aperiodic CSI relating to the at least one CSI process and reporting the same to the base station, on the basis of the one aperiodic reference signal.

Abstract: Disclosed in the present invention is a method for reporting, by a terminal, channel status information (CSI) to a base station in a wireless communication system. The CSI reporting method is characterized by including the steps of: transmitting, to a base station, first CSI including a rank indicator in a first period unit; transmitting, to the base station, second CSI including a vertical precoding matrix index in a second period unit within the first period; and transmitting, to the base station, third CSI including horizontal precoding matrix index in a third period unit within the second period.

Abstract: According to one embodiment of the present invention, a method of decoding, by a user equipment, a downlink signal in a wireless communication system comprises the steps of: receiving a semi-persistent zero power-channel state information reference signal (SP ZP CSI-RS) resource configuration from a base station; and decoding a downlink signal according to the SP ZP CSI-RS resource configuration. The SP ZP CSI-RS resource configuration includes a plurality of SP ZP CSI-RS resources and information on whether or not each of a plurality of the SP ZP CSI-RS resources is used can be indicated or configured by the base station.

Abstract: Disclosed in the present application is a method by which a terminal reports channel state information (CSI) to a base station in a wireless communication system. Specifically, the method comprises the steps of: calculating a first CSI as to compare the same with CSI which has been most recently reported; reporting the first CSI to a base station if the calculated first CSI is not the same as the CSI which has been most recently reported; and reporting a second CSI to the base station if the calculated first CSI is the same as the CSI which has been most recently reported, wherein the second CSI is CSI calculated on the basis of the assumption that interference affecting a terminal has been removed.

Abstract: The present invention provides a method for reporting channel status information (CSI) for downlink transmission to an eNode B (eNB) by a user equipment (UE) in a wireless communication system. Specifically, the method comprises the steps of: receiving a channel status information-reference signal (CSI-RS) from the eNB; calculating the CSI on the basis of the CSI-RS under the assumption that a dual-precoder including a first precoder and a second precoder is applied; and reporting the CSI to the eNB, wherein the step of calculating the CSI includes a step for assuming that at least one of the first precoder and the second precoder is cyclically employed from a predetermined precoder candidate set on the basis of a predetermined resource unit; and information associated with the at least one precoder and information associated with the predetermined precoder candidate set are provided from the eNB through radio resource control (RRC) layer signaling.
