摘要
为满足国际电信联盟对4G通信网络峰值速率及最大带宽的需求,载波聚合技术作为LTE-A(LTE-Advanced)系统的一项关键技术得到了研究。重点阐述了载波聚合技术的工作原理、关键技术以及实际应用。
To satisfy the requirement of International Telecommunication Union-Radio group(ITU-R) for4 G peak rate and the maximum bandwidth, the Carriers Aggregation(CA) is an key technology for LTE-Advanced(LTE-A) system. The work principle, key technologies and application of CA are expatiated in this paper.
