摘要

在异构蜂窝网络中,提出了一种基于宏用户公平性的宏基站功率控制算法。在该算法中,宏用户根据飞基站的干扰选择信道。然后,通过非合作博弈,推导出各信道MBS的功率解。所构建的游戏效用函数不仅考虑了系统容量,还考虑了用户间的公平性。同时,证明了纳什均衡的存在性。仿真结果表明,该方法缩小了宏观用户容量之间的差距,明显提高了中断概率。

Fairness Based Macro Base Station Power Control Algorithm in Heterogeneous Cellular Networks
In heterogeneous cellular networks, a macro base station(MBS) power control algorithm based on macro users' fairness is proposed in this paper. In this algorithm, macro users choose channels based on the interference from femtocells. Then, the power solution of MBS in every channel is derived through the non-cooperative game. The constructed game utility function considers not only the system capacity, but also the fairness among users. Meanwhile, the paper proves the existence of Nash equilibrium(NE). The results in simulation show that the gap among macro users' capacity is narrowed and outage probability is obviously improved.
