摘　　要：针对4G用户的快速增长以及4G网络规模的持续扩大,2016年国内三大运营商将大规模升级LTE网络至4G+,即在原有4G网络的基础上利用载波聚合技术。介绍了载波聚合技术的背景及功能,对载波聚合技术的频谱聚合方式、载波管理以及载波聚合部署方案进行了简要介绍。结合国内运营商现有频谱资源,探讨了国内三大运营商载波聚合频谱组合方式,最后针对中国联通的现有频谱资源,给出了中国联通载波聚合部署的方案建议,为即将升级的4G+网络建设提供一些参考。With the rapid growth of 4G users and the continued expansion of the scale of the 4G network. In the year of 2016, the three major domestic carriers will be large-scale LTE network upgrade to 4G ＋ , which is based on the 4G network using the carrier aggregation technology. In this paper, the background and function of carrier aggregation technology are briefly introduced. The spectrum of carrier aggregation technology, polymerization method, carrier scheduling and carrier aggregation deployment scheme are analyzed briefly. Combined with the existing spectrum resources of domestic carriers, the combination mode of carrier aggrega- tion spectrum of the three carriers in China is discussed. Finally, according to the existing spectrum resources of China Unicom, the proposed scheme is proposed. To provide some reference for the upcoming 4G ＋ network construction.
