Abstract
A base station enables a mobile station to employ a random access retransmission scheme in a wireless communication network. The mobile station includes a plurality of antennas configured to communicate with the base station. The mobile station also includes a processing circuitry coupled to the plurality of antennas. The processing circuitry is configured to perform a random access during a random access channel (RACH) burst. The processing circuitry also is configured to at least one of: transmit a random access signal with at least one of an initial transmit power level and an initial transmit beamwidth, and, in response to a random access attempt failure, change at least one of a transmit (Tx) power level and a Tx beamwidth and retransmit the random access signal.
