Patent ID: 7076264

Claim:
A method for controlling a power level of transmissions from a first station in a communication system comprising: receiving, at the first station, an indicator relating a measured signal to noise ratio to an expected signal to noise ratio of a previous transmission; determining the power level of the next transmission according to said received indicator; measuring, at a second station, a signal to noise ratio of a transmission from the first station; determining, at the second station, an expected signal to noise ratio of the transmission; determining the indicator in accordance with said measured signal to noise ratio and the expected signal to noise ratio; and transmitting, from the second station, the indicator, wherein said measuring at a second station a signal to noise ratio comprises: measuring a signal to interference ratio over a first predetermined amount of time; measuring a noise to interference ratio over a second predetermined amount of time; and dividing the measured signal to interference ratio by the measured noise to interference ratio.
