摘要
文章首先介绍了LTE异构网和LTE立体组网技术,在此基础上,重点研究高铁和密集城区的LTE覆盖技术。讨论了如何应对高铁LTE覆盖的多普勒频移效应问题,并给出了高铁沿线覆盖和隧道两种环境下的组网方式建议。最后,探讨了如何采用LTE异构网和立体组网技术,通过合理的网络布局来解决密集城区的容量和深度覆盖问题。
This paper firstly introduced the LTE heterogeneous network and LTE multilayer network technology,and then focus on LTE coverage technology for high-speed rail and dense urban areas.Where need to consider how to solve the problem of the Doppler shift effect of LTE coverage of HSR,the paper gave suggestion for LTE coverage networking for HSR line and tunnels environments.And discussed how to use the LTE heterogeneous networks and multilayer network technology to solve the LTE issue of capacity-limited and depth coverage on dense urban environment in a reasonable net-work layout.
