Claim 9:
10. A method for beam failure recovery (BFR) performed by a user equipment (UE), the method comprising:
receiving a special cell BFR configuration corresponding to a first special cell, the special cell BFR configuration including at least one of a resource list for beam failure detection (BFD) and a resource list for new beam identification (NBI), the first special cell comprising one of a primary cell (PCell) and a primary secondary cell group (SCG) cell (PSCell);
detecting a beam failure condition in the first special cell;
determining a first new candidate beam index for the first special cell based on the special cell BFR configuration;
transmitting a scheduling request (SR) for BFR;
receiving a first uplink (UL) grant in response to the transmitted SR;
transmitting a beam failure recovery request (BFRQ) in the received first UL grant; and
receiving a second UL grant in response to the transmitted BFRQ.
