摘要
3GPP LTE标准即将冻结,其应用乃至商用都变得指日可待。首先介绍了LTE的概况,着重分析了LTE空中接口(Uu)协议栈的架构及分层结构,又从用户平面和控制平面进行了分解,最后对RRC子层进行了重点剖析,分析并探讨了LTE中RRC的几个关键变化和技术,包括状态简化、分布式架构、动态资源分配等。RRC的这些方法使得系统更加合理化。
With the completion of 3 GPP LTE standard, the commercial application of LTE can be expected soon. This paper first gives a brief introduction to LTE, and analyzes the Uu protocol stack and hierarchical structure, Finally, RRC layer is discussed including some key technologies, such as state simplification, distributed control and dynamic resource allocation. These technologies in RRC enable the system to be more reasonable.
