摘要
针对3GPP最新发布的LTE标准,对LTE空中接口协议栈RLC子层AM传输模式中的数据重传过程进行了研究。介绍了LTE无线接入网空中接口协议栈的结构,详细阐述了空中接口协议栈中无线链路控制RLC子层确认AM数据传输模式的数据重传ARQ的设计方案,最后给出了在协议栈软件中AM传输模式的数据重传测试结果,得出设计方案是可行的,符合LTE协议的要求,达到了LTE数据重传的目标。
Based on the 3GPP LTE standard released recently, the mechanism of RLC data retransmit in LTE radio protocol stack is researched, the structure of air interface protocol stack in LTE radio access network is mainly introduced, the design principle of RLC data retransmit is expatiated, a test result of data retransmit in LTE air interface protocol stack software is gave finally. It can be judged that the proposed design program is feasible on the basis of analysis of test results, and can meet the requirements of LTE protocol and reach the goal of data retransmission in LTE.
