Beam failure recovery for a multi-transmission/reception point in a primary cell

A method for wireless communication at a network device, comprising:

• transmitting, to a user equipment (UE), a configuration for a carrier associated with a primary cell associated with the network device, the carrier configured with a first control resource set pool index value and a second control resource set pool index value;
• transmitting an indication of a set of candidate beams available for a beam failure recovery procedure, the set of candidate beams comprising a first subset of candidate beams associated with the first control resource set pool index value and a second subset of candidate beams associated with the second control resource set pool index value;
• and
• receiving, based at least in part on the UE detecting a beam failure on the carrier on an active beam of the primary cell associated with the first control resource set pool index value or the second control resource set pool index value, an access message indicating a new candidate beam, the new candidate beam selected from the set of candidate beams based at least in part on the UE monitoring a resource associated with the first control resource set pool index value or the second control resource set pool index value, the resource mapped to the new candidate beam.

An apparatus for wireless communication at a user equipment (UE), comprising:

• a processor,
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive a configuration for a carrier associated with a primary cell, the carrier configured with a first control resource set pool index value and a second control resource set pool index value;
• receive an indication of a set of candidate beams available for a beam failure recovery procedure, the set of candidate beams comprising a first subset of candidate beams associated with the first control resource set pool index value and a second subset of candidate beams associated with the second control resource set pool index value;
• detect a beam failure on the carrier on an active beam of the primary cell that is associated with the first control resource set pool index value or the second control resource set pool index value;
• select a new candidate beam from the set of candidate beams based at least in part on monitoring a resource associated with the first control resource set pool index value or the second control resource set pool index value, the resource mapped to the new candidate beam;
• and
• transmit an access message indicating the new candidate beam during the beam failure recovery procedure.
