User equipment and beam failure recovery method

A user equipment (UE), comprising:

• at least one processor;
• and
• at least one non-transitory computer-readable medium coupled to the at least one processor and storing one or more computer-executable instructions that, when executed by the at least one processor, cause the UE to:
• receive beam failure instance indication from lower layers;
• start or restart a beamFailureDetectionTimer;
• increment a BFI COUNTER by 1, the BFI_COUNTER being a counter for a beam failure instance indication;
• initiate a Random Access procedure for beam failure recovery on a basis of a value of the BFI COUNTER;
• reset the BFI COUNTER to 0 in response to determining that the beamFailureDetectionTimer has expired;
• reset the BFI COUNTER to 0 with regard to the Random Access procedure for beam failure recovery in response to determining that the Random Access procedure for beam failure recovery is successfully completed;
• and
• forgo resetting the BFI COUNTER to 0 with regard to the Random Access procedure for beam failure recovery in response to determining that the Random Access procedure for beam failure recovery is not successfully completed.
