Abstract:
A method for reporting an aperiodic channel condition in a wireless communication system, according to an embodiment of the present invention, is performed by a terminal. The method comprises the steps of: receiving, from a base station, setting for one or more channel state information (CSI) processes including a plurality of channel state information-reference signals (CSI-RS) resources, wherein precoding is applied to each of the plurality of CSI-RS resources; receiving an aperiodic CSI report request from the base station; and transmitting, to the base station, an aperiodic CSI for a CSI process indicated by the aperiodic CSI report request, wherein, if a certain time has not elapsed after a CSI-RS resource index for the CSI process indicated by the aperiodic CSI report request is reported, the transmitted aperiodic CSI may include a CSI-RS resource index for a CSI process which has not been updated.
