Abstract
A method and apparatus are disclosed from the perspective of a User Equipment (UE). In one embodiment, the method includes the UE being served and/or configured with a first cell and a second cell. The method also includes the UE transmitting a beam failure recovery request via a PRACH (Physical Random Access Channel) in the second cell in response to the UE detecting that all links associated with monitored control resource set(s) in the second cell have failed. Furthermore, the method includes the UE transmitting a first report via a PUCCH (Physical Uplink Control Channel) in the second cell in response to the UE detecting that all links associated with monitored control resource set(s) in the first cell have failed.
