The article first analyzes the complexity of high speed wireless environment, introduces the tech-nology characteristics of FDD-LTE. Then through the link budget, it discusses about choosing suitable propagation models. Finally, it calculates the base sta-tion coverage radius in High-speed-railway's scene and distance between base stations considering the overlapping area.
