1. A method comprising:
receiving configuration information related to a channel state information (CSI) report;
receiving a CSI-reference signal (CSI-RS) based on a resource set for channel measurement, which is related to the CSI report; and
performing the CSI report based on the CSI-RS,
wherein, the resource set includes N (N>1) CSI-RS resources for N transmission and reception points (TRPs), and
wherein, based on the configuration information being related to a coherent joint transmission (CJT), codebook subset restriction information related to a number of antenna ports is respectively configured for the N CSI-RS resources in the configuration information.
