Claim 7:
8. The UE of claim 6, wherein:
the BFRR is in a form of at least one of:
a dedicated control resource set (CORESET) or a search space addressed to a UE specific cell radio network temporary identifier (C-RNTI), whose quasi co-location (QCL) source RS is the one or more NBI RSs for the new beam recovery;
a TCI state indication for a physical downlink control channel (PDCCH) from a CORESET associated with the one BFD RS set for which the beam failure event was detected; and
an uplink grant for a new transmission for a same hybrid automatic repeat request (HARD) process as the MAC CE for the BFR event; and

the CB RA transmission is triggered according to at least one of:
the BFRR is not received before the BFR timer expires;
a maximum number of beam failure instance (BFI) count is achieved for the at least two BFD RS sets within a time window;
the maximum number of BFI count is achieved for at least one BFD RS set and a scheduling request (SR) for BFR is not configured; and
the maximum number of BFI count is achieved for at least one BFD RS set and the uplink grant to the BFRQ is not received before the BFR timer expires.
