Techniques and applications of managing bfd-rs set configured with multiple beams

A method of wireless communication at a user equipment (UE), comprising:

• detecting a beam failure instance (BFI) indication of a first beam based on a beam failure detection (BFD)-reference signal (RS) (BFD-RS) from a base station, the BFI indication corresponding to a radio link quality associated with the first beam being below a link quality threshold, the BFD-RS being associated with a BFD-RS set corresponding to a plurality of beams including the first beam;
• incrementing a BFI counter in response to the detected BFI indication of the first beam irrespective of a status associated with other beams in the plurality of beams corresponding to the BFD-RS set;
• and
• performing a beam failure recovery (BFR) procedure in response to the BFI counter reaching or exceeding a corresponding BFI counter threshold.

An apparatus for wireless communication at a base station, comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• transmit, to a user equipment (UE), a configuration set associated with a beam failure detection (BFD)-reference signal (RS) (BFD-RS) set corresponding to a plurality of beams including a first beam via a radio resource control (RRC) message;
• transmit, to the UE, a BFD-RS associated with the first beam, the BFD-RS being associated with the BFD-RS set, wherein based on the configuration set, incrementation of a beam failure instance (BFI) counter is in response to a BFI indication of the first beam based on the BFD-RS irrespective of a status associated with other beams in the plurality of beams corresponding to the BFD-RS set, and the BFI indication corresponds to a radio link quality of the first beam being below a link quality threshold;
• and
• perform a beam failure recovery (BFR) procedure based on the BFI counter reaching or exceeding a corresponding BFI counter threshold.
