载波聚合终端技术研究分析

Research and Analysis of Carrier Aggregation Terminal Technology

载波聚合技术作为4G网络演进的关键技术,三大运营商启动了载波聚合的试验和商用。载波聚合的商用化,需要网络侧和终端侧的技术支撑。首先阐述载波聚合在网络侧部署情况和终端侧的支撑情况,剖析分析载波聚合终端芯片支持情况,并且给出现网载波聚合终端品牌、终端用户数占比等统计分析,最后总结未来技术发展趋势。

Three domestic operators have begun the test and commercial of carrier aggregation, which is a key technology of the evolu- tion of the 4G network. The commercial of CA requires the support from both network side and terminal side. It begins with introduction of CA deployment situation and CA-supporting condition of terminals, then analyzes the terminal chip for CA. Moreover, statistical analysis of brands and proportion of CA terminals in current network will be presented. Technology development prospects in the future are summarized in the end.
