Claim 13:
14. An apparatus for wireless communication by a user equipment (UE), the apparatus comprising:
a memory; and
at least one processor coupled to the memory and configured to:
determine whether a contention-free random access channel (RACH) procedure with a dedicated preamble or a contention-based RACH procedure for beam failure recovery with a base station based on reception of a RACH configuration from the base station for at least one of the contention-free RACH procedure with the dedicated preamble or the contention-based RACH procedure;
perform, based on detection of a failure of a serving beam through which the UE communicates with the base station, the determined one of the contention-free RACH procedure with the dedicated preamble or the contention-based RACH procedure for the beam failure recovery, wherein the dedicated preamble is determined using a beam corresponding to a reference signal, wherein the reference signal is selected based on a power metric associated with the reference signal.
