针对中继蜂窝系统,提出一种联合调度的公平性优化模型.在分析中继网络小区用户通信方式的基础上,从边缘用户调度的公平性角度考虑充分发挥不同调度算法的优势,对基站采用最大载干比调度算法,中继器节点运用比例公平的联合调度算法对小区频率资源进行合理分配,提高边缘用户信号质量和小区的容量及覆盖率.仿真结果表明,联合调度算法的边缘用户性能优于传统调度算法,系统吞吐量提高20％.%The fairness optimization model of joint schedule for relay network is proposed. The communication way for the relay network and the advantages of different schedule algorithm for edge users fairness are both analyzed. Frequency resources are distributed more properly and capacity is improved by using the joint schedule with maximum carrier to interference ratio and proportional fairness. Simulation analysis results show that the joint schedule fairness optimization for relay network can improve the performance of edge user and throughput up to 20%.
