Abstract

Deploying smallcell networks achieves great spatial reuse at the cost of severe cross-tier interference from concurrent transmission. This paper addresses the downlink cross-tier interference pricing and power control for orthogonal frequency division multiple access (OFDMA) heterogeneous Networks (HetNets), where a macrocell underlaid with several femtocells.We assume that the macrocell protects its transmission by pricing the interference on each orthogonal subchannel and each femtocell base station (FBS) determines the power allocation strategy accordingly.Then, a Stackelberg game is used to formulate the mentioned model. Existence and uniqueness of the Stackelberg equilibrium (SE) are analyzed. In addition, a distributed interference pricing and power update algorithm (DIPPU) with guaranteed convergency is proposed to achieve the SE. Simulation results validate the proposed algorithm and show its fast convergence. Due to the non-cooperative manner, the proposed scheme can approach the cooperative scheme in terms of capacity of femtocells with reduced communication overhead effectively.

OFDMA HetNets中下行链路跨层干扰定价与功率控制

部署小蜂窝网络可以实现很大的空间重用，但代价是并发传输造成严重的跨层干扰。本文讨论了正交频分多址(OFDMA)异构网络(HetNets)的下行链路跨层干扰定价和功率控制，其中一个宏基站与几个飞基站底层。假设宏蜂窝通过对每个正交子信道上的干扰进行定价来保护其传输，并且每个飞蜂窝基站(FBS)决定相应的功率分配策略。然后，利用Stackelberg博弈来建立模型。分析了Stackelberg均衡的存在性和唯一性。在此基础上，提出了一种保证收敛的分布式干扰定价与功率更新算法(DIPPU)。仿真结果验证了该算法的快速收敛性。由于该方案采用非合作方式，因此在蜂窝容量方面接近合作方案，有效地降低了通信开销。
