1. A method for channel state reporting by a terminal in a wireless communication system, the method comprising:
receiving configuration information for a plurality of aperiodic channel state information reference signal (CSI-RS) resource sets through a Radio Resource Control (RRC) signaling;
receiving an aperiodic CSI request in downlink control information (DCI) in a cell-specific manner; and
reporting aperiodic CSI based on at least one aperiodic CSI-RS resource set of the plurality of aperiodic CSI-RS resource sets, wherein the at least one aperiodic CSI-RS resource set is determined among the plurality of aperiodic CSI-RS resource sets based on the cell-specifically received aperiodic CSI request,
wherein the at least one aperiodic CSI-RS resource set is received after a time period from when the aperiodic CSI request is received, and
wherein the time period is determined based on an offset value received through the RRC signaling for each of the plurality of aperiodic CSI-RS resource set.
