Terminal, radio communication method, and base station
A terminal according to one aspect of the present disclosure includes a receiving section that receives control information for mapping one or more TCI states to a codepoint of one transmission configuration indication (TCI) field and that receives one or more pieces of downlink control information (DCI) for indicating a first TCI state applicable to a plurality of types of first signals and a second TCI state applicable to a plurality of types of second signals, and a control section that applies the first TCI state to the first signals and that applies the second TCI state to the second signals, based on the control information and the codepoint of the TCI field included in the DCI. The first signal and the second signal are at least one of two physical downlink control channels (PDCCHs) linked to each other, a single frequency network (SFN) PDCCH, an SFN physical downlink shared channel (PDSCH), physical uplink shared channel (PUSCH) repetition transmission, and physical uplink control channel (PUCCH) repetition transmission. According to one aspect of the present disclosure, it is possible to appropriately perform TCI state indication.

a receiver that receives:
first downlink control information (DCI) being associated with a first value of a control resource set (CORESET) pool index and indicating a first transmission configuration indication (TCI) state;
second DCI being associated with a second value of a CORESET pool index and indicating a second TCI state;
first radio resource control (RRC) signaling associating one of the first TCI state and the second TCI state to a first resource; and
second RRC signaling associating one of the first TCI state and the second TCI state to a second resource; and
a processor that applies, based on the first RRC signaling, one of the first TCI state and the second TCI state to the first resource, and applies, based on the second RRC signaling, one of the first TCI state and the second TCI state to the second resource.
