Beam failure recovery for multiple transmit receive points

A base station for wireless communication, comprising:

• one or more memories;
• and
• one or more processors, coupled to the one or more memories, configured to:
• receive, from a user equipment (UE), a recovery request that indicates a failure of a beam, wherein the beam is one of a first beam associated with a first transmit receive point (TRP) or a second beam associated with a second TRP, and wherein the recovery request indicates a new beam associated with a first physical uplink control channel (PUCCH) group for the first TRP if the beam is the first beam, or associated with a second PUCCH group for the second TRP if the beam is the second beam, and wherein the first PUCCH group is associated with a first control resource set (CORESET) pool index, a first set of beam failure detection (BFD) reference signals, and a first set of new beam identifier (NBI) reference signals, and wherein the second PUCCH group is associated with a second CORESET pool index, a second set of BFD reference signals, and a second set of NBI reference signals;
• transmit a response to the recovery request;
• and
• receive a communication using the new beam.

A user equipment (UE) for wireless communication, comprising:

• one or more memories;
• and
• one or more processors, coupled to the one or more memories, configured to:
• detect failure of a first beam for a first transmit receive point (TRP) and failure of a second beam for a second TRP;
• transmit a recovery request that indicates a first new beam associated with the first TRP and a second new beam associated with the second TRP, the first new beam associated with a first physical uplink control channel (PUCCH) group for the first TRP and the second new beam associated with a second PUCCH group for the second TRP, wherein the first PUCCH group is associated with a first control resource set (CORESET) pool index, a first set of beam failure detection (BFD) reference signals, and a first set of new beam identifier (NBI) reference signals, and wherein the second PUCCH group is associated with a second CORESET pool index, a second set of BFD reference signals, and a second set of NBI reference signals;
• and
• reset, after receiving a response to the recovery request, the UE to beam sweep with the first new beam and the second new beam.
