  • Publication number: 20240129767
    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 radio resource control (RRC) message including a beam failure detection configuration which is information for configuring N beam failure detection resource sets and is associated with a downlink bandwidth part that is a part of a bandwidth of the cell; and a controller configured to individually detect beam failure for each of the N beam failure detection resource sets in the radio communication using the downlink bandwidth part.

  • Publication number: 20240129014
    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 radio resource control (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 whether or not to initiate a random access procedure for the cell based on a state of recovery from the beam failure in a case where the beam failure has been detected for all of the N beam failure detection resource sets.

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.
