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.

Abstract: Disclosed are a method for transmitting and receiving a channel state information reference signal in a wireless communication system and a device therefor. Specifically, a method for transmitting, by a base station, a channel state information-reference signal (CSI-RS) in a wireless communication system includes: transmitting configuration information of the CSI-RS to user equipment (UE); and transmitting, to the UE, the CSI-RS through one or more antenna ports, in which the position of an orthogonal frequency division multiplexing (OFDM) symbol for transmitting the CSI-RS may be configured by the configuration information, and the position of a resource element (RE) for transmitting the CSI-RS may be determined by M RE units (M is 1 and/or 2 and/or 4 and/or 8).
