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 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.

Abstract: A method of transmitting, by a user equipment (UE), power measurement information related to beam reporting in a wireless communication system includes: receiving downlink control information (DCI) triggering reporting of the power measurement information; receiving a downlink reference signal for reporting of the power measurement information; and transmitting, to a base station, power measurement information determined based on the received downlink reference signal. A minimum required time for reporting of the power measurement information is (i) calculated as the sum of a first minimum required time from the last timing of the downlink reference signal to a transmission timing of the power measurement information and a second minimum required time between DCI triggering the downlink reference signal and reception of the downlink reference signal or (ii) calculated based on a pre-configured threshold value related to reporting of the power measurement information.
