ABSTRACT:
A system and method is taught for controlling a power level of transmissions in a communication system. A first station of the communication system transmits signals on a communication channel and a pilot channel. A second station of the communication system measures a signal to noise ratio of the received signal, determines an expected signal to noise ratio of the received signal, determines an indicator in accordance with said measured signal to noise ratio and the expected signal to noise ratio, and transmits the indicator. The indicator is received at the first station the indicator and determines the power level of the next transmission according to said received indicator. Additionally, methods and systems for the measurement of the signal to noise ratio of the received signal, the determination of the expected signal to noise ratio of the received signal, and the determination of the indicator are disclosed.
