LTE-U/LAA技术及应用部署研究

Research on LTE-U/LAA Technology and Its Deployment

面对全球移动宽带业务的飞速发展和频率资源的枯竭,LAA技术提出了一种LTE使用公共频率资源的方法,通过技术上与Wi-Fi等共存,实现了频率资源共享。通过分析中国5 GHz公共频率资源以及系统共存,LAA多种应用场景具有部署可行性,是解决热点容量问题的一个有效方法。

In view of the fast development of global mobile broadband service and the frequency resource exhaustion,LAA presents a method on using public frequency with LTE. Based on the physical and MAC layer technology,sharing the public frequency resource is realized with the coexistence of LTE and Wi-Fi. Based on the analysis of 5 GHz frequency resource of China and coexistence of multiple systems,LAA can be deployed in several kinds of scenes,and is an effective method to improve the capacity of hot spots.
