摘　　要：TD-LTE-Advanced作为TD-LTE的增强版本,在TD-LTE基础上引入了一系列新技术特性,如载波聚合,增强型MIMO,中继等。本文介绍了这些技术的物理层、协议栈、高层关键过程及相应的增强内容,分析了技术增强所带来的终端设计和测试上的挑战。As an enhanced version ofTD-LTE, TD-LTE-Advanced R10 introduced a series of new technical features, such as Carrier Aggregation, enhanced MIMO,Relay. This paper details the principle of these techniques, including the key points of physical-level, protocol stack, high-level and the enhanced contents. At the end of the article, the author analyzed the challenges on terminal designing and RF test along with the technical enhancement.
