Forward power control for a mobile communication system is provided on a fra me by frame basis during a soft handoff of a mobile station from a source base station to a target base station. Each base station runs independent but identical algorithms. A selector runs the same power control algorithm as ea ch base station and coordinates power control between the two base stations and the mobile station during the soft handoff. The results of the algorithm run by the selector are delayed because of backhaul. The selector provides the base stations with traffic gain and frame delay information corresponding to the traffic gain. The base station ASIC, modifies the base station power output according to the SNR data received from the mobile station and the traffic gain and frame delay information received from the selector. Providi ng the frame delay information permits forward power control even when there is delay from when the selector computes the traffic gain and the traffic gain is programmed into the base station application specific integrated circuit.</S DOAB>
