1. A terminal comprising:
a transmitter that transmits a maximum number of Channel State Information Reference Signal (CSI-RS) resource configurations for Channel State Information (CSI) measurement that can be concurrently targeted by Layer-1 or Layer-2 (L1 or L2) measurement reporting as capability information;
a receiver that receives the CSI-RS resource configurations for the CSI measurement by Radio Resource Control (RRC) signaling; and
a processor that controls CSI measurement reporting based on a group index that is an integer and that collectively indicates a group of two or more of the CSI-RS resource configurations respectively indicating resources of different CSI-RSs corresponding to different beams for the CSI measurement,
wherein the processor controls the CSI measurement reporting based on a list configured by another RRC signaling, in which a plurality of group indexes including the group index are respectively associated with different groups of the CSI-RS resource configurations,
wherein each of the plurality of the group indexes is an integer,
wherein the processor determines a reporting bit size of uplink L1 or L2 signaling for the CSI measurement reporting according to a configured number of CSI-RS resource configurations that are concurrently targeted by the L1 or L2 measurement reporting, and
wherein the group index is provided by Medium Access Control Control Element (MAC CE) and Downlink Control Information (DCI).
