Abstract: The present disclosure provides a method and an apparatus for measuring and reporting channel state information (CSI) in a wireless communication system. Specifically, a method for reporting CSI by a terminal in a wireless communication system comprises: a step of receiving CSI reporting setting information related to CSI reporting; a step of receiving one or more CSI-reference signals (CSI-RSs); and performing the CSI reporting by using a measurement value estimated by at least one specific CSI-RS among the one or more CSI-RSs, wherein the CSI reporting setting information includes gap information for setting a measurement gap for estimating the measurement value, and the at least one specific CSI-RS can be determined on the basis of the gap information and the time point of performing the CSI reporting.

Abstract: Provided are method and device for transmitting/receiving a downlink signal. A user equipment-specific reference signal (UE-RS) can be transmitted to a user equipment. A downlink control channel and a downlink data channel for the user equipment can share the UE-RS. Antenna port information about a transmission antenna port of the downlink control channel and/or a transmission antenna port of the downlink data channel is provided to the user equipment. The user equipment receives UE-RS(s) corresponding to the antenna port information and thus receives the downlink control channel and the downlink data channel.

Abstract: Disclosed is a method by which a terminal reports channel status information (CSI) to a base station in a wireless communication system, so as to perform a demodulation reference signal (DM-RS)-based downlink transmission through a multi-layer. Particularly, the method comprises the steps of: receiving a channel status information-reference signal (CSI-RS) from the base station; calculating the CSI on the basis of the CSI-RS, on the assumption that a dual pre-coder composed of a first pre-coder and a second pre-coder is applied; and reporting the calculated CSI to the base station, wherein column vectors of the second pre-coder are composed of a single discrete Fourier transform (DFT) vector.
