Abstract: A terminal includes: a reception unit configured to receive a signal from another terminal and to perform sensing in a resource pool; a control unit configured to perform DRX (Discontinuous reception) in the resource pool, and determine a resource to be used for transmission, based on a result of the sensing; and a transmission unit configured to perform data transmission to the another terminal using the determined resource. The control unit determines an operation of sensing in DRX inactivity time, based on a sensing method.

Abstract: A terminal according to one aspect of the present disclosure includes a receiving section that receives information for indicating at least one of a first Transmission Configuration Indication state (TCI) state common to both downlink (DL) and uplink (UL), a second TCI state common to the DL, and a third TCI state common to the UL, the first TCI state, the second TCI state, and the third TCI state being associated with a certain cell that is other than a serving cell and has a physical cell ID different from a physical cell ID of the serving cell, and a control section that applies, to a specific channel for the certain cell, at least one of the first TCI state, the second TCI state, and the third TCI state indicated in the information. According to one aspect of the present disclosure, it is possible to appropriately perform transmission/reception to/from another cell having a physical cell ID different from a physical cell ID of a serving cell.
