在IEEE 802.16网络中，基站基于订户站的QoS要求和带宽请求大小向订户站分配资源。当用户站具有由基站分配的上行链路许可时，或者通过参与竞争解决机制，用户站可以发送带宽请求。本文提出了分析计算的参数，控制竞争解决过程中的IEEE 802.16网络。特别地，考虑退避开始/结束值和请求传输机会的数量。仿真结果验证了理论计算的正确性。他们还表明，自适应参数调整的结果在一个更好的吞吐量相比，静态配置。同时，满足所有时序要求。
In the IEEE 802.16 networks, the base station allocates resources to subscriber stations based on their QoS requirements and bandwidth request sizes. A subscriber station can send a bandwidth request when it has an uplink grant allocated by the base station or by taking part in the contention resolution mechanism. This paper presents analytical calculations for parameters that control the contention resolution process in the IEEE 802.16 networks. In particular, the backoff start/end values and the number of request transmission opportunities are considered. The simulation results confirm the correctness of theoretical calculations. They also reveal that the adaptive parameter tuning results in a better throughput when compared to a static configuration. At the same time, all the timing requirements are met.
