文章通过对IEEE802.16中竞争方式的请求与分配关系进行分析，提出了一种竞争时隙的动态分配方法。与固定分配方式相比，该分配方法可有效提高上行带宽的使用效率，并减小竞争请求引入的时延。仿真结果表明，在各种负载条件下，该分配算法都能较高效地使用系统的上行带宽。

By analyzing the relationship between the request and allocation of contention in IEEE802.16, this paper proposes a dynamic allocation algorithm of contention slot. Compared with the fixed allocation, the proposed algorithm can effectively improve the utilization efficiency of uplink bandwidths and decrease the delay brought about by contention request. The simulation results show the proposed algorithm can effectively use the uplink bandwidths of the system under all kinds of load conditions.
