1. A wireless communication method by a user equipment (UE), comprising:
generating, by the UE, a beam failure recovery (BFR) medium access control (MAC) control element (CE) if the UE determines that at least one BFR has been triggered and not cancelled, uplink shared channel (UL-SCH) resources are available for a new transmission, and the UL-SCH resources can accommodate the BFR MAC CE plus its subheader as a result of logical channel prioritization (LCP), wherein the BFR MAC CE is generated in a multiplexing and assembly procedure;
generating, by the UE, a truncated BFR MAC CE if the UE determines that at least one BFR has been triggered and not cancelled, if UL-SCH resources are available for a new transmission and if the UL-SCH resources can accommodate the truncated BFR MAC CE plus its subheader as a result of LCP;
otherwise, triggering a scheduling request (SR) for secondary cell (SCell) beam failure recovery for each SCell for which BFR has been triggered and not cancelled if the UE determines that at least one BFR has been triggered and not cancelled.
