    Abstract: A method for receiving, by a user equipment (UE), a channel state information reference signal (CSI-RS) in a wireless communication system, includes receiving, from a base station, CSI-RS resource configuration information related to a numbering for a plurality of CSI-RS resources through a radio resource control (RRC) signaling, wherein the CSI-RS resource configuration information includes first CSI-RS configuration information and at least one second CSI-RS configuration information; and determining numbers for the plurality of CSI-RS resources based on the received CSI-RS resource configuration, wherein a specific CSI-RS resource among the plurality of CSI-RS resources corresponds to a value configured in the first CSI-RS configuration information, and at least one CSI-RS resource except the specific CSI-RS resource among the plurality of CSI-RS resources corresponds to a value configured in the second CSI-RS configuration information, and wherein the specific CSI-RS resource is a CSI-RS resource related to a lowest number among the plurality of CSI-RS resources.

    Abstract: In an aspect of the present invention, a method for reporting channel state information (CSI) of a UE in a wireless communication system includes: receiving, from an eNB, CSI-RS resource information related to a CSI-RS resource to which a channel state information-reference signal (CSI-RS) is mapped; receiving the CSI-RS transmitted through one or more antenna ports from the eNB based on the received CSI-RS resource information; and reporting CSI generated based on the received CSI-RS to the eNB, in which the CSI-RS resource is configured by aggregating a plurality of CSI-RS resources, and the aggregated CSI-RS resources are respectively positioned in different subframes on a time axis or in different resource blocks on a frequency axis.

    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.
