摘要
802.16作为一种宽带无线接入技术,能够支持多种业务的传输。分组调度是为它提供Qos保证的重要手段和工具,好的分组调度算法能在时延,吞吐量和公平性等方面取得折中。本文对其调度进行了设计,提出了分级的联合上下行链路的分组调度结构,并分析了各级的调度策略,既满足了各业务流的Qos,又保证了用户间的公平性。
As a broadband wireless access technology, 802.16 supports various services transmission. Packet scheduling is one important method and tool to provide Qos guarantee. The good scheduling algorithms can make a compromise in delay, system throughput, fairness and so on. This paper designs the scheduling mechanism of IEEE 802.16. We propose a hierarchical packet scheduling structure, which considers both uplink and downlink., and analyze the strategy. By doing so,our method not only satisfies the Qos of each service flow, but also guarantees the fairness among users.
