摘要
从移动用户终端UE接收的角度出发,详细分析了TD-SCDMA系统消息接收的全过程,提出了系统消息的解码方案。首先剖析了承载系统消息的物理信道的传输格式、解调和下行同步过程;讨论了系统消息进行广播时,空中接口各层协议头的添加情况;最后按照无线资源管理层RRC中的“SYSTEM INFORMATION”消息的层次结构,具体解析了各信息单元的含义,给出了解码流程图,并详细描述了其工作原理和过程。
In this paper, from th system information＇ s broadcast, e po and of view of receiver, we analyz present a decoding scheme of syste e the receiving proced m messages. First, we ure of introduce the physical channel＇ s transmit format, demodulation and downlink synchronization procedures. Second, we discuss the protocol header in every layer of radio interface. Last, we analyze the information element＇s meaning and function in the ＂ SYSTEM INFORMATION＂ message of RRC layer, give the decoding flow chart, and describe the working principle and process.
