针对经典多用户调度算法只偏重于信道条件或者公平性的缺点, 提出了一种实用型Max C/I(最大载干比)和一种实用型PF(比例公平)调度算法。这两种算法将信道条件、用户业务需求和吞吐量作为度量值的计算因子。仿真结果表明, 这两种调度算法能兼顾用户承载QoS(服务质量)要求和频谱效率, 实现吞吐量与公平性的平衡。

As the classical multi-user scheduling algorithms are biased toward channel conditions or fairness, this paper presents a practical Maximum Carrier to Interference ratio (Max C / I) algorithm and a practical Proportional Fair (PF) scheduling algorithm. These two algorithms take the channel condition, user service requirements and throughput as factors of the scheduling metrics. Simulation results show that they can take into account both the user-bearer QoS requirements and spectral efficiency and achieve the balance between throughput and fairness.
