摘　　要：载波聚合技术能将离散的频谱聚合使用,使系统带宽达到100M,从而达到LTE-A系统提高传输带宽的要求。使用排队论对两种基本的载波调度结构JCS和ICS进行研究,并对基于JSQ的ICS调度结构进行改进,设计出基于ICS-JSQ的自适应调度结构。通过系统仿真分析,ICS-JSQ自适应调度结构较JCS有更低的系统复杂性,比ICS有更高的系统资源利用率。Carrier aggregation technology can aggregate discrete spectrum to make the system bandwidth up to 100M and meet the LTE-A system re- quirements so as to improve the transmission bandwidth. In this paper, two basic system resource scheduling schemes, JCS （Joint Carrier Scheduling） and ICS （Independent Carrier Scheduling） are researched based on queuing theory, and the ICS-JSQ adaption schemes is designed on the basis of ICS. The simulation shows that the system based on ICS-JSQ adaption schemes can achieve almost the same performance but lower complexity than JCS, and higher resource utilization rate than ICS.
