Abstract: A method of reporting, by a user equipment (UE), channel state information (CSI) in a wireless communication system, includes: receiving, by the UE and from a base station (BS), downlink control information (DCI) related to an aperiodic CSI report that is to be performed by the UE in a slot n; determining, by the UE, a value nCQI_ref based on a number of symbols Z′ related to a time for computing the CSI; determining, by the UE, a CSI reference resource as being a slot n−nCQI_ref in a time domain that is to be used for the aperiodic CSI report; and transmitting, by the UE and to the BS, the aperiodic CSI report in the slot n, based on the CSI reference resource being slot n−nCQI_ref. The CSI may be calculated by using the most recent A CSI-RS, and thereby the most recent CSI may be reported.
