Abstract: A terminal according to an aspect of the present disclosure includes a receiving section that receives a channel state information (CSI) report configuration indicating that at least one of CSI for a single transmission/reception point (STRP) and CSI for multi-TRP (Multi TRP (MTRP)) is reported, and a control section that performs control to include, in a CSI report, at least one of the CSI for a STRP and the CSI for MTRP, based on information included in the CSI report configuration. According to an aspect of the present disclosure, even when MTRP is used, CSI measurement and report can be appropriately performed.

Abstract: A terminal is disclosed that includes a receiver that receives Channel State Information (CSI) reporting configuration information which is a Radio Resource Control (RRC) information element. The terminal also includes a processor that ignores a second RRC parameter regarding report quantity when the terminal is configured with a first RRC parameter regarding report quantity by the CSI reporting configuration information. The processor also performs a control to report Layer 1 Signal to Interference plus Noise Ratio (L1-SINR) when quantity for reporting L1-SINR is indicated by the first RRC parameter. In other aspects, a radio communication method and a system are also disclosed.

Abstract: A terminal according to one aspect of the present disclosure includes a receiving section that, when different physical cell IDs are configured for a plurality of transmission/reception points (TRPs), receives information related to a downlink reference signal from a second TRP out of the plurality of TRPs by using higher layer signaling, and a control section that controls transmission of an uplink signal on the basis of the information. According to one aspect of the present disclosure, it is possible to perform appropriate communication when different physical cell IDs are configured for a plurality of TRPs.
