摘　　要：随着2I2C用户的发展和LTE流量猛增,LTE无线网利用率不断攀升,容量问题成为LTE无线网面临的主要问题之一。首先,在分析2I2C用户发展和无线资源利用率增长现状基础上,介绍了载波聚合、扇区分裂、微站吸热、256QAM、4×4MIMO和非授权频段部署LTE的技术特点,最后对上述容量解决方案提出了部署建议和利弊分析。With the development of 2I2C subscribers and the soaring of data traffic,the resource utilization rate of LTE wireless network increased continuously. The problem of capacity is one of the major problems of LTE wireless network. Firstly based on analyzing the development of 2I2C subscribers and the state of LTE's wireless resource utilization rate,the technical characteristics of carrier aggregation,sector division,micro cell absorbed capacity,256 QAM,4×4 MIMO and deploying LTE on unlicensed spectrum had been described. Lastly the deployment proposals of abovementioned capacity solutions had been proposed and the advantages and disadvantages of capacity solutions also had been analyzed.
