Based on high performance ARQ, it gives two kinds of mechanism which can guarantee QoS of different traffic. One is multi-queue in one partial-window-multireject ARQ. The other is more than one ARQ in every user platform.

• 在高性能ARQ 协议的基础上,给出了两种ARQ 协议中多业务质量保证机制,一种是单ARQ 多队列机制,一种是多ARQ 机制,并对这两种机制进行仿真性能分析及比较。
