摘　　要：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 al-gorithm. These two algorithms take the channel condition, user service requirements and throughput as factors of the schedu-ling metrics. Simulation results show that they can take into account both the user-bearer QoS requirements and spectral effi- ciency and achieve the balance between throughput and fairness.
