摘要

针对Macro-Femto网络中Femtocell与Macrocell之间的干扰问题，提出了一种基于分簇的资源分配机制。该机制结合图论及凸优化理论对毫微微节点分簇；随后采用基于速率公平的子信道分配算法对毫微微用户和宏用户分别进行子信道分配；利用分布式功率分配算法对完成信道分配的系统进行功率分配。仿真结果表明，该机制有效地抑制了Macro-Femto网络中存在的跨层干扰及同层干扰，提升了平均速率，同时满足了用户的速率公平性需求，使用户获得更高的满意度。

Abstract

A based-cluster resource allocation mechanism was proposed for suppressing interference between Femtocell and Macrocell in Macro-Femto network.The mechanism included three parts

FBS was put in disjoint clusters by graph theory and convex optimization

then a sub-channel allocation algorithm was adopted to assign sub-channel to the FUE and MUE based on fairness of rate.In the end

power allocation was performed by using distributed algorithm.Simulation results show that the proposed mechanism effectively suppresses cross-tier and co-tier interference in the Macro-Femto network

improves the average rate

meanwhile satisfies the requirements of fairness of rate

which makes users more satisfied.
