This paper addresses the Distributed Power Adaptation (DPA) problem on the downlink for wireless cellular networks. As a consequence of uncoordinated local scheduling decisions in classical networks, the base stations produce mutual uncontrolled interference on their co-channel users. This interference is of a variable nature, and is hardly predictable, which leads to suboptimal scheduling and power control decisions. While some works propose to introduce cooperation between BS, in this paper, the authors propose instead to introduce a model of power variations, called trajectories in the powers space, to help each BS to predict the variations of other BS powers.
