Claim:
1. A mobile station comprising: a plurality of antennas configured to communicate with at least one base station; and a processing circuitry coupled to the plurality of antennas, the processing circuitry configured to perform a random access during a random access channel (RACH) burst, wherein the processing circuitry is configured to: in response to achieving the minimum Tx beamwidth, the processing circuitry is configured to boost a Tx power level by a ΔP in successive iterations until the random access is successful or a maximum Tx power level, P in response to achieving the maximum Tx power level, the processing circuitry is configured to decrease the Tx beamwidth by a ΔW in successive iterations until the random access is successful or the minimum Tx beamwidth, W
