异构Femtocell网络中基于用户公平性的干扰协调

Interference Coordination Based on Users' Fairness in Heterogeneous Femtocells Networks

为使含有家庭基站和宏基站的异构网络(HetNet)中各用户的服务质量需求都能满足并达到用户阃的公平性,在功率限制条件下对宏用户中最小的用户数据速率最大化,将此最小用户速率提供给家庭基站用户,获得各家庭基站用户的目标信干噪比(SINR),再利用对分法调整家庭基站的发射功率。仿真结果表明,该方法能够保证最小的宏用户数据速率且提高异构网络用户阀的公平性。

To make the service quality requirements of each user in heterogeneous network （HetNet） which contains femtocells and macro base stations meet and achieve the fairness among users, under the condition of power constraints, and it＇ s effective to maximize minimum user data rate among Macro users, this user minimum rate to station users in home base is provided, the target SINR of users among home base station is obtained. And finally adjusting transmission power of the base stations by using bisection method will meet requirements. The simulation results show that this method can guarantee a minimum data rate and improve the user fairness in heterogeneous network.
