Abstract

A terminal according to one embodiment of the present disclosure comprises: a reception unit for receiving a configuration that indicates an X number of channel measurement resources with respect to an X number of transmission / reception points (TRP) for coherent joint transmission; and a control unit for, on the basis of said configuration, controlling CSI reporting that includes X pieces of channel state information (CSI) corresponding respectively to the X number of channel measurement resources. According to one embodiment of the present disclosure, CSI reporting can be performed appropriately for CJT.
