摘　　要：在IEEE802.16e标准中,保证QoS的调度算法一直是人们研究的热点,它涉及到从单一业务到多级别业务的调度服务。对多级别业务调度的支持是保证系统性能的重要技术之一。本文针对多级别业务常用的分层调度和联合调度策略,从系统吞吐量、QoS性能和公平性等方面对之进行的仿真分析和性能比较。仿真结果表明联合调度策略综合性能较好。In IEEE802.16e, the scheduling algorithms for guaranteeing the quality of service （QoS） have always been a focus for reseach. It involves the scheduling services, ranging from one service type to multiple sefvice type. The support to multi-class traffic is an important technique for ensuring the system performance. For the two strategies of layered scheduling and joint scheduling used in multi-class traffic, simulation analyses and performance comparisons are carried out from system throughput, QoS and fairness. The simulation results indicate that the overall performance of the joint scheduling is better.
