1. A method for a User Equipment (UE), comprising:receiving a Random Access Channel (RACH) configuration from a network node, wherein the RACH configuration indicates at least one Physical Random Access Channel (PRACH) resource for a beam failure recovery;
receiving a timing advance command from the network node;
starting or restarting a time alignment timer when receiving the timing advance command;
initiating a contention free random access procedure for the beam failure recovery by using the at least one PRACH resource for the beam failure recovery when detecting a beam failure and the timing alignment timer is running; and
releasing the at least one PRACH resource for the beam failure recovery indicated by the RACH configuration when the timing alignment timer expires.
