| 摘 要： | 首先对基于IEEE802．16标准定义的QoS架构进行了扩充，然后对BS分组调度器进行了具体的设计，将其分为服务信息模块、信道状态反馈模块和服务调度模块3个部分。为不同类型的服务流提供QoS支持，设计了MAC—PHY跨层调度器，综合考虑无线信道的状态和MAC层业务QoS要求，对业务进行3级调度：

| Abstract: | The definition of QoS framework was extended based on IEEE 802.16 standard, and then the base station （BS） packet scheduler was designed. The scheduler consists of service information module, channel status feedback module, and service scheduling module, tn order to support QoS for different service, MAC-PHY cross-layer scheduler was designed. The scheduler considers wireless channel status and quality of service （QoS） in MAC layer, and the three level scheduling was carried. |
