摘　　要：本文主要介绍了LTE-Advanced(LTE-A)系统的多载波聚合技术。多载波聚合技术是LTE-A系统的一个关键技术,它能解决LTE-A系统对频带资源的需求。文章首先阐述了多载波聚合技术的优势;随后介绍了聚合技术下载波带宽的设计,多个子载波的聚合方式,传输数据流的聚合方式等几方面内容;最后,总结了多载波聚合技术面临的挑战和应用前景。The multi-carriers aggregation technology was introduced in this paper, which is to be used in LTE-Advanced （LTE-A） system and can solve the bandwidth requirements of LTE-A system. Firstly the advantages of multi-carrier aggregation techno- logy are presented. Then the implements of carrier aggregation are introduced, which include the design of transmission bandwidth, the schemes of sub-carrier aggregation and data streams aggregation and so on. Finally the future challenges and prospect of multi-carriers aggregation technology are summarized at the end of the paper.

关 键 词：LTE-ADVANCED系统 多载波聚合技术 频谱效率
