Abstract: A method of transmitting channel state information (CSI) in a wireless communication system includes: receiving, from a base station, configuration information related to CSI; receiving, from the base station, a CSI-reference signal (CSI-RS) on a plurality of CSI-RS resources; and transmitting, to the base station, first CSI based on the configuration information. The plurality of CSI-RS resources corresponding to the configuration information are configured with (i) one or more channel measurement resources (CMRs) configured to be used to derive CSI based on a single CMR and (ii) one or more CMR pairs configured to be used to derive CSI based on a single CMR pair, unless there is a specific configuration by the configuration information, based on the first CSI being CSI derived based on a single CMR, any CMR included in the one or more CMR pairs may be not used to derive the first CSI.
