Beam group specific medium access control-control element (mac-ce) based beam failure recovery (bfr) requests

A user equipment (UE), comprising:

• a memory;
• a processor coupled to the memory and configured to:
• detect a beam failure of at least one beam of a beam group;
• trigger a beam failure recovery (BFR) in response to the detection of the beam failure of the at least one beam of the beam group;
• and
• generate a BFR medium access control-control element (MAC-CE) that includes BFR information associated with the beam group;
• and
• a transceiver coupled to the processor and configured to:
• transmit the BFR MAC-CE that includes the BFR information associated with the beam group using a transmission resource.

A base station (BS), comprising:

• a memory;
• a processor coupled to the memory and configured to:
• configure a user equipment (UE) for transmission of a beam failure recovery (BFR) MAC-CE;
• and
• a transceiver coupled to the processor and configured to:
• receive the BFR MAC-CE from the UE, the BFR MAC-CE identifying one or more failed beams and one or more candidate replacement beams.
