Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. In a method of reporting channel state information (CSI) in a coordinated multi-point (CoMP) system, the method performed by a terminal,
receiving Synchronization Signal Block (SSB) from a first base station and a second base station, respectively;
receiving System Information (SI) from the first base station and the second base station, respectively, based on each the SSB;
performing Random Access (RA) procedure with the first base station and the second base station;
receiving first configuration information related to a channel state information (CSI) report of a first bandwidth part (BWP) from the first base station and second configuration information related to a CSI report of a second BWP from the second base station,
wherein the first BWP is composed of a plurality of first subbands including at least one first subband for the CSI report, and
wherein the second BWP is composed of a plurality of second subbands including at least one second subband for the CSI report;
based on that the at least one first subband and the at least one second subband partially or entirely overlap, obtaining a first CSI for overlapping at least one subband; and
reporting the first CSI to the first base station and the second base station.
