Ranging method for mobile communication system based on orthogonal frequency division multiple access scheme

摘要

The method involves determining a number of initial ranging codes (RCs), bandwidth request RCs, periodic RCs for an initial ranging process, bandwidth request ranging process, and periodic ranging process, respectively. A backoff value of the periodic RCs is determined according to number of the RCs. The initial RCs, the bandwidth request RCs, the periodic RCs, and the backoff value are sent to reception sides.
