Optimal Power Control Between Two Opportunistic Cooperative Base Stations

In this paper, the authors consider sum rate maximization problem between two opportunistic cooperative Base Stations (BS). They propose a simple criterion to decide if the cooperation is binary or sharing power controls. When sharing power cooperation is identified, the resulting problem is a sum rate maximization problem for interfering wireless links under a sum power constraint. They derive the optimal power allocation solution for this power sharing problem. Simulation results show tremendous performance gains compared to the non-cooperative schemes.
