1. A method of receiving an aperiodic channel state information reference signal (CSI-RS) resource by a user equipment (UE) in a wireless communication system, the method comprising:
receiving periodicity information and first offset information for a periodic CSI-RS resource;
receiving configuration information related to an aperiodic CSI-RS resource set including at least one aperiodic CSI-RS resource; and
receiving the at least one aperiodic CSI-RS resource based on the configuration information and the first offset information,
wherein the periodicity information is used for the periodic CSI-RS resource other than the at least one aperiodic CSI-RS resource,
wherein the configuration information includes second offset information,
wherein the second offset information is applied to the aperiodic CSI-RS resource set, and
wherein the first offset information is applied to each of the at least one aperiodic CSI-RS resource.
