/Communication Apparatus, Base Station, And Communication Method
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 trigger beam failure recovery (BFR) for one beam failure detection resource set with which the beam failure has been detected. The communicator is configured to cancel all the triggered BFRs for the one beam failure detection resource set in a case where a MAC PDU is transmitted, the MAC PDU including a BFR MAC CE including information regarding the detected beam failure.
