With the rapid development of e-commerce and internet

the need of high speed data’s transmmison increases strongly and the mobile terminal users on high-speed rail could have good experience with the arrival of the 4G era. Because of the structure characteristics and high speed mobility of high-speed rail

there are some diffi cult problems in the planning of TD-LTE high-speed rail such as the Doppler effect

the loss of penetration

the switch between cells and so on. This paper does some research on the problems above and put forward specifi c solutions combined with construction of a city’s TD-LTE highspeed rail.
