两层异构网络中femtocell研究进展与展望

摘要

对femtocell研究进展进行了细致分析和探讨，着重讨论两层异构网络中频率资源分配、干扰管理和接入控制3个主要议题，同时也分析回程链路、用户移动性和公平性等其他相关问题。最后论述femtocell应用前景和归纳未来研究方向。%An overview was given for femtocell in details on recent research progress. Three topics were mainly ad-dressed in two-tier femtocell-macrocell wireless networks:spectrum allocation, interference management and access con-trol. In addition, backhaul, user mobility, fairness and other related issues were studied as well. In the end, the prospects of femtocell application and future trends were concluded.
