Abstract: A terminal according to one aspect of the present disclosure includes: a receiving section that receives multiple downlink control information (DCI) for indicating multiple transmission configuration indication (TCI) states; and a control section that determines, based on an index related to a transmission/reception point associated with a control resource set scheduling or triggering a signal to which a TCI state is to be applied, which TCI state among the multiple TCI states to apply to the signal, whereineach of the multiple TCI states is a TCI state to be applied to both a downlink (DL) signal and an uplink (UL) signal, or a TCI state to be applied to a DL signal and a TCI state to be applied to a UL signal. According to one aspect of the present disclosure, it is possible to appropriately perform TCI state indication.

Abstract: A terminal includes: a communication unit configured to perform an uplink or downlink communication by using a frequency band in which aggregation is performed by carrier aggregation; and a control unit configured to assume that, in a case where scheduling is performed in the aggregation-performed frequency band according to a unit including a plurality of component carriers, a maximum number of PDCCH candidates that can be monitored per slot in an active downlink BWP or of non-overlapped CCEs is determined based on sub-carrier spacings included in the plurality of component carriers.

Abstract: A terminal according to an aspect of the present disclosure includes: a receiving section that receives first configuration information related to a physical uplink control channel (PUCCH), second configuration information related to a physical uplink shared channel (PUSCH), and third configuration information related to uplink simultaneous transmission using multiple panels; and a control section that controls, based on the first configuration information, the second configuration information, and the third configuration information, assumption related to transmission of the PUSCH and the PUCCH in the same time domain and transmission of at least one of the PUSCH and the PUCCH. An aspect of the present disclosure enables UL transmission to be appropriately controlled even when the UL transmission is performed using multiple panels.
