摘要

摘要: 干扰的有效管理是超密集小蜂窝网中的一个研究难点。该文提出将超密集小蜂窝网中的小区干扰协调和分簇相结合的算法，通过分配最优的功率降低干扰，最大化系统吞吐量。根据干扰的程度，将干扰强的小蜂窝划为一个簇，同一个簇内的小蜂窝共享频谱资源，协作为用户服务，簇与簇之间实现频谱复用。仿真结果表明，该算法在网络密集部署时，有效地减小干扰，提高系统吞吐量。

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.
