摘要
为了解决TD-LTE在高速轨道场景中的覆盖问题,通过研究TD-LTE在高速轨道场景下的组网方式、链路预算以及天线的选型,提出了TD-LTE在高速轨道沿线的站间距设置及在高速轨道不同隧道场景下的覆盖解决方案,从而应用到不同高速轨道场景下的覆盖中。
In order to solve the coverage of TD-LTE in the scenario of high-speed rail transit, the networking mode, link budget and antenna selection of TD-LTE were investigated. The configuration of the distance between the base stations along the high-speed track and the coverage solution in different tunnel scenarios were presented to be applied to the coverage solution in the scenarios of different high-speed rail tracks.
