在LTE到LTE-Advanced系统的演进过程中，更宽频谱的需求将会成为影响演进的最重要因素之一，如何有效利用频域上分散的频谱资源，通过资源整合以获得更高的系统带宽是必须解决的问题，为此3GPP提出了载波聚合技术。首先给出了载波聚合（CA）在移动通信网中的业务流程设计；然后讨论和分析了CA的拉网测试结果、UE峰值测试结果和高速率路段测试结果；最后指出了载波聚合待解决的问题。

In the evolution of LTE to LTE-Advanced system, the demand of wider spectrum will become one of the most important factors affecting the evolution. The problems about how to effectively use the scattered spectrum in the frequency domain and to achieve higher system bandwidth through resources integration must be addressed. Based on this, 3GPP proposes carrier aggregation technology. First the business process design of carrier aggregation(CA) in mobile communication network is presented. And then the DT test results, UE peak test results and high-rate link test results of CA are discussed and analyzed. Finally, the problems of carrier aggregation are pointed out.
