本文针对3GPP中的相邻确认帧冗余大和HIPERLAN标准中确认方式单一导致的确认效率低下的问题,提出了新一代蜂窝移动通信系统数据链路层的部分窗口多拒绝ARQ算法,并分析了该ARQ算法的链路时延;最后将理论分析结果和仿真结果作比较,证明了理论分析结果的正确性,并分析了控制信道误帧对链路时延的影响及解决办法。
In this paper, aim at the problem of inefficient acknowledgement with large redundancy of coterminous acknowledgement frame in 3GPP and simple acknowledgement type in HIPERLAN, the Multiple Rejects Automatic Repeat Request Protocol of link layer in the new generation eelluar mobile communication system is put forward, and we also make a performance analysis on the link layer delay of the ARQ protocol. In the end, we compare the result between approximate model and simulation results to prove the correctness of the approximate model result, and illustrate the influence to link layer delay with the error control frame and the solution.
