摘　　要：载波聚合技术作为一种将LTE零碎频段整合为"虚拟"更宽频段进而提升网络容量的有效方案,成为运营商未来网络发展的必然选择。分析了辅载波激活的实现原理,从设备实现角度,给出不同的辅载波激活实现方案,进一步从激活实现方案中总结出影响载波聚合网络系统增益的几种因素,探索它们之间的影响。最后依据仿真数据,分析出激活门限的设置对网络性能增益的影响。LTE carrier aggregation as an effective program to integrate fragmented band as ＂virtual＂ wider band and thus enhancing the network capacity, become an inevitable choice for operators to respond to future network development. It analyzes the secondary carrier activation principle, from the perspective of the device to achieve, gives the different implementations of the secondary carrier activation, further, sums up several factors affecting the carrier aggregation network system gain from the active implementation, and then explores the influence between them. Finally, according to the simulation data, it analyzes the impact of the activation threshold setting on network performance gain.
