摘要
介绍了LTE技术的显著特征及LTE-A将达到的演进目标,对LTE向LTE-A平滑演进过程中所涉及的多载波聚合、下行MIMO增强、中继、协同多点传输等关键技术作了简介,比较详细地分析了Vo LTE的优点,还分析了TD-LTE和LTE FDD二者的差异,总结了TD-LTE的优势,希望业界看到TD-LTE行将迅速追上LTE FDD成为4G的主流趋势,充分发挥我国自主技术的作用,顺应技术发展潮流,齐心协力,使FDD网与TD网能协同发展,建设全球最为先进高效的移动互联网。
In this paper, the outstanding features of LTE technology and the evolution goal of LTE-A are introduced. Several key techniques in the smooth evolution process from LTE to LTE-A are described, including multi-carrier aggregation, downlink MIMO enhancement, relay and coordinated multi-point transmission. The advantages oI VoLTE and the difference between TD-LTE and LTE FDD are analyzed in-depth. The advantages of TD-LTE are summarized in order that the industry fitness TD-LTE to be the mainstream tendency of 4G instead of LTE FDD. In order to promote the coordinated development of FDD and TD networks, as well as build the most advanced and efficient mobile lnternet around the globe, China should fully utilize independent innovations and adapt to the trend of technical development.
