摘　　要：首先简要分析了802.16协议中的服务质量(QoS)业务模型,然后提出了一种新颖的用于802.16媒体访问控制(MAC)层的QoS调度架构。该架构包括3个用于不同业务的调度器,1个用于信道补偿的调度器和1个映射(MAP)信息生成器。该调度架构能够有效地区分业务类型,保证不同类型业务的带宽请求,并且能很好地解决无线信道特殊性带来的调度问题。最后简单分析了该调度架构的优点。In this paper, the QoS service model of 802.16 protocol is discussed briefly,then a new QoS scheduling architecture which is composed of three schedulers for different services,a scheduler for channel compensation and a MAP information generator is proposed for MAC layer of 802.16 protocol. The scheduling architecture can effectively distinguish service type and meet the needs of different services for bandbroad. It can also resolve the scheduling problems resulted from particularity of wireless channel. Last the advantages of this architecture is discussed briefly.
