1. A method for reporting channel state information (CSI) performed by a UE in a wireless communication system, the method comprising:
transmitting UE capability information related to a plurality of panels;
receiving configuration information related to reporting of CSI related to multiple first panels among the plurality of panels;
receiving a downlink reference signal (DL RS) based on the configuration information;
performing measurements for the DL RS based on the multiple first panels and at least one second panel other than the multiple first panels among the plurality of panels; and
transmitting CSI related to a measurement result for the DL RS,
wherein, based on at least one second measurement result based on the at least one second panel being better than first measurement results based on the multiple first panels, the measurement result for the DL RS is based on the at least one second panel among the plurality of panels, and the CSI includes information indicating the at least one second panel.
