摘要

本文针对TD-LTE网络在高铁覆盖场景下的组网

分析了其对TD-LTE系统产生的影响及网络覆盖要求。针对高铁覆盖场景下的多普勒频移、小区频繁切换、高穿透损耗三大难题分别提出解决方案:频偏补偿克服多普勒频移、合理站址布局克服车体高穿透损耗、多CP组网方式克服小区间频繁切换。文章最后介绍了高铁专网测试中开启9:3:2特殊时隙配比提升业务下载速率。

Abstract

Based on the high-speed rail TD-LTE networking coverage

this paper analyses the elements which effect on TD-LTE system. The paper gives the solutions to serve the high-speed rail coverage problems: doppler shift

frequency switch

high penetration loss. The main solution is that frequency offset compensation to overcome the doppler frequency shift

reasonable layout of the site to overcome the high penetration loss

multi cyclic prefi x to overcome frequent switching. Finally

high-speed rail network test based on the 9:3:2 special time slot allocation to improve the download rate.
