ABSTRACT:
A spread spectrum communication system has a mobile station and a base station. The base station transmits a spread spectrum signal and a threshold. The mobile station receives the spread spectrum signal and the threshold. A received power level of the received spread spectrum signal is measured. The received power lever is compared to the threshold. The mobile station's transmission level is adjusted based on in part a result of the comparison.
