Coverage Coordination in Self-Organizing Femtocell Networks

In this paper, a novel coverage adjustment algorithm to be used in femtocell networks is proposed. An important aspect of the proposed algorithm is that channel state information is not required in the adjustment process. Moreover, perfect fairness among users is achieved in a distributed manner with minimal information exchange. The theoretical analysis shows the convergence of the proposed algorithm under dynamic conditions. The performance is further verified by simulations and comparisons to other algorithms.
