Abstract: A user equipment (UE) performs radio communication with a base station that manages a cell including N (N?2) transmission/reception points. The UE comprises: a communicator configured to receive a radio resource control (RRC) message from the base station, the RRC message including information for configuring N beam failure detection resource sets; and a controller configured to individually detect beam failure for each of the N beam failure detection resource sets. The controller is configured to determine, in a case where there is a beam failure detection resource set that does not provide a reference signal resource for detecting the beam failure, the reference signal resource based on a control resource set (CORESET) pool index associated with the beam failure detection resource set.
