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.
