摘　　要：介绍了LTE-A载波聚合的原理,并对影响LTE载波聚合系统性能的网络参数含义进行阐述,包括载波聚合终端渗透率、辅载波激活门限以及资源调度策略。并通过设置不同的终端渗透率、资源调度策略,对小区系统性能进行仿真,具体包括小区吞吐量以及用户吞吐率,分析了基础调度和差异化调度以及终端渗透率带来系统性能差异的原因,通过对仿真结果的分析,最终给出LTE载波聚合资源调度策略及建议。LTE-Advanced carrier aggregation principle is introduced and system performance parameters which affect the performance of LTE carrier aggregation system are expounded, including the CA UE proportion, the secondary carrier activation threshold and the resource scheduling strategy. For different network configuration parameters, the cell throughput, user throughput and the reason for the difference between system performances are simulated and analyzed under different scheduling strate- gy. At last, the scheme and the suggestion of LTE carrier aggregation resource scheduling strategy is proposed.
