multi-cell networks

In multi-cell cooperative networks, base station (BS) cooperation with BS clustering is indispensable for alleviating cooperation costs (e.g., data and channel estimation sharing via backhaul links). The performance of such BS cooperation is fundamentally limited by the unmanageable out-of-cluster interference. The out-of-cluster interference power is mainly a function of a set of the distances from the out-of-cluster BSs to users, the path-loss exponent, the cluster size, and the cooperative transmission strategies used in the out-of-cluster.
