TD-SCDMA系统RLC非确认模式传输过程研究

Research on Process of RLC Data Blocks Transfer in UM of TD-SCDMA System

无线链路控制子层(RLC子层)位于TD-SCDMA系统空中接口协议栈的第二层,它的数据传输功能在对TD-SCDMA的研究和实现中有着极其重要的地位。RLC子层向高层提供三种模式的数据传输服务:透明模式(TM)、非确认模式(UM)和确认模式(AM)。文中重点研究在非确认模式(UM)下,TD-SCDMA中RLC子层处理和传输数据的过程。

RLC lies in the 3^rd sublayer of air interface protocol stack of TD-SCDMAsystem and its data blocks transfer service plays a very important role in TD-SCDMA research and implementation. RLC sublayer provides higher layers with three data blocks transfer modes, including transparent mode, unacknowledged mode and acknowledged mode. This paper focuses on the procedure of RLC data blocks process and transfer under the UM of TD-SCDMA.
