Kind Code:
A1
Abstract:
A method for reporting channel state information (CSI) by a terminal in a wireless communication system according to an aspect of the present invention may comprise the steps of: receiving, from a base station, CSI-reference signal (CSI-RS) resource information that is information on a CSI-RS resource to which a CSI-RS is mapped; receiving, from the base station, the CSI-RS which is transmitted through at least one antenna port, on the basis of the received CSI-RS resource information; and reporting, to the base station, the CSI generated on the basis of the received CSI-RS, wherein the CSI-RS resource is formed by aggregating a plurality of CSI-RS resources, and the aggregated CSI-RS resources are positioned in different subframes on the time axis or in different resource blocks on the frequency axis respectively.
