Abstract Effective interference management is one of research difficulties in dense small cell network. This paper proposes a new algorithm in which inter-cell interference is combined with clustering. And the system achieves maximizing system throughput by the optimal power allocation. According to the degree of interference, the cells are divided into several clusters and the cells with the bigger inter-cell interference are divided in the same cluster. The cells within a cluster share the spectrum and serve the user terminals with cooperation and the cells within different clusters may reuse the spectrum. Simulation results show that the proposed algorithm can effectively decrease the interference and improve system throughput in densely deployed small networks.
