Classification: CPC H | IPC H

Claim 19:
20. A method of wireless communication by a base station providing a cell, the method comprising:
configuring a first set of parameters for beam failure recovery by a user equipment (UE), the first set of parameters being associated with one of a contention-free random access channel (RACH) procedure with a dedicated preamble or a contention-based RACH procedure; and
transmitting at least the first set of parameters to enable the UE to determine whether to use the contention-free RACH procedure or the contention-based RACH procedure for the beam failure recovery; and
receiving a dedicated preamble corresponding to a beam corresponding to a reference signal when the UE initiates a contention-free RACH procedure for the beam failure recovery, wherein the dedicated preamble is determined using the beam ID-corresponding to the reference signal, wherein the reference signal is selected based on a power metric associated with the reference signal.
