摘　　要：无线链路控制(RLC)层是LTE系统中数据通路的核心组成部分。为满足LTE系统数据传输的高速性,根据3GPP最新发布的标准,具体分析了非确认模式(UM)的数据传输过程,然后详细描述了服务数据单元(SDU)组装成非确认协议数据单元(UM PDU)和UM PDU重组为一个完整SDU的具体实现方案。经实践验证,该方案完全满足LTE系统的要求。In order to meet the speed requirement of data transmission in LTE system, according to the latest 3GPP protocol, the paper analyzed the process of UM data transfer specifically. Then it expatiated upon the specific implementation about the SDU being assembled into the UM PDU and UM PDU being reconstituted as a complete SDU. It is verified that the program can fully satisfy the requirements of LTE system.
