Adaptive down bias to power changes for controlling random walk

Abstract

A wireless communication network (20) utilizes a down bias to minimize or eliminate random walk when controlling a transmit power between a base station (38) and a mobile station (40). In a disclosed example, a link quality monitoring module (54) determines the quality of a link between the mobile station (40) and the base station (38). A power control module (52) applies a down bias, which is dependent on the determined link quality, to a transmit power correction for minimizing random walk. In a disclosed example, the down bias varies linearly and inversely proportionally to the quality of the link between the mobile station and the base station.
