这种方案称为基于局部域的重传方案。
We call such a scheme local-scope-based retransmission scheme.
仿真结果表明，与传统方案相比，自适应选择重传方案在高误帧率环境下以较低的误包率、略大的传输时延获得了较高的TCP吞吐量。
Numerical results demonstrate ASR-ARQ can achieve much lower packet error rate with slightly longer delay and higher TCP throughput than the conventional scheme.
同时提出了通过限制实时性业务重传时间来改进D - ED CA机制的初步方案，并对该方案进行了仿真与分析。
The revised D-EDCA is proposed by restricting the retransmitted times of the real-time traffics. Furthermore the performance of the revised D-EDCA schemes is analyzed briefly.
