Abstract

The proposed scheme utilizes local information and a predictive model to provide feedback control commands for power adjustments. A sufficient condition that ensures system stability is obtained. In addition, the bound of the received carrier-to-interference ratio (CIR) is derived in the presence of short-term fading. The bound of the received CIR is shown to be a function of the power control step size and the target CIR. Simulation results were obtained to verify the theoretical derivations.
