Configuration of physical uplink control channel (pucch)-beam failure recovery (bfr) for transmission reception point (trp) specific bfr

A method of wireless communication by a network entity, comprising:

• receiving, from a user equipment (UE), a beam group specific beam failure recovery (BFR) scheduling request (SR), in accordance with one or more rules, for an uplink (UL) grant to transmit a beam failure recovery request (BFRQ) specific to a beam group in which a beam failure is detected;
• transmitting the UL grant in response to the SR;
• and
• receiving, from the UE, the BFRQ specific to the beam group in which the beam failure was detected, based on the UL grant.

An apparatus for wireless communication, comprising:

• a memory;
• and
• one or more processors coupled to the memory, the memory and the one or more processors being configured to:
• communicate with at least two transmission reception points (TRPs) using beams associated with at least two beam groups, each of the at least two beams groups associated with one of the at least two TRPs;
• detect a beam failure in a beam group of the at least two beam groups;
• transmit a beam group specific beam failure recovery (BFR) scheduling request (SR), in accordance with one or more rules, for an uplink (UL) grant to transmit a beam failure recovery request (BFRQ) specific to the beam group in which the beam failure was detected;
• receive the UL grant in response to the SR;
• and
• transmit the BFRQ specific to the beam group based on the UL grant.
