Abstract

Macrocells may suffer serious interference induced by the deployment of co-channel femtocells. To mitigate the cross-interference, we design a novel price-based power control method, with each femtocell user's delay quality-of-service (QoS) provisioning, in uplink OFDMA two-tier femtocell networks. Assuming that the macrocell base station (MBS) protects itself by pricing the interference from femtocell users (FU), a Stackelberg game is formulated with a goal to reach the joint utility maximization of the macrocell and the femtocells subject to a maximum tolerable interference power at the MBS. The Nash Equilibrium (NE) of its non-cooperative subgame is found with optimization theory firstly, and then a particle swarm optimization (PSO) aided power allocation (PSO-PA) algorithm is proposed to achieve the final Stackelberg Equilibrium (SE). Simulation results show that our proposed power allocation algorithm can converge quite fast and bring much higher effective capacity (EC) at FU side.
两层飞蜂窝网络中基于价格的统计时延QoS控制
大细胞可能受到同信道飞细胞部署引起的严重干扰。为了减少交叉干扰,我们设计了一种新的基于价格的功率控制方法,在上行OFDMA两层移动蜂窝网络中,每个移动蜂窝用户的延迟服务质量(QoS)供应。假设宏蜂窝基站(MBS)通过对来自飞蜂窝用户(FU)的干扰进行定价来保护自己,以在最大可容忍干扰功率下实现宏蜂窝和飞蜂窝的联合效用最大化为目标,建立了Stackelberg博弈。首先利用最优化理论找到其非合作子博弈的纳什均衡(NE),然后提出粒子群优化(PSO)辅助功率分配(PSO- pa)算法实现最终的Stackelberg均衡(SE)。仿真结果表明,本文提出的功率分配算法收敛速度快,在FU端具有较高的有效容量(EC)。
