乔卫斌, 杨勇, 严希, et al. Study on the coverage improvement of high-speed rail LTE outdoor station[J]. 2020, 33(3): 20-24. DOI: 10.13992/j.cnki.tetas.2020.03.006.
China Telecom launched the 4G project of Beijing-Guangzhou and Shanghai-Kunming highspeed rail
establish LTE FDD to ensure users get good data and VoLTE service experience. This paper is aimed at the propagation characteristics of LTE FDD cells in high-speed rail scenarios
describe the site selection and coverage parameter setting method in the outdoor scene of high-speed rail
and calculate the azimuth and downtilt of the high-speed rail scene. Finally
the correctness of the method for improving the coverage of high-speed rail outdoor stations is demonstrated in combination with actual cases.
