摘要
调度算法是宽带无线接入系统为分类业务提供QoS保证的重要手段和工具。但无线信道的特殊性,如高误码率和突发变化等,往往给无线调度算法的设计增加了相当的难度。文章根据宽带无线接入标准IEEE 802.16中MAC层的QoS机制,提出了一种结合无线信道状态的IEEE802.16 QoS调度结构,分析了该结构下的调度策略和依此结构设计的调度算法模型,最后讨论了有待进一步完善的课题。
Scheduling algorithm is an important tool to guarantee QoS for classification service in broadband wireless access （BWA） system. But the characteristics of the wireless channel, such as high error-rate and outburst change, add some difficulties for the design of wireless scheduling algorithms. In this paper, the author puts forward an IEEE 802.16QoS scheduling architecture combined with wireless channel condition, analyses the scheduling strategy and scheduling algorithms model based on this structure, and discusses some issues for further research.
