Abstract: The rapidly growing service requirements of high-speed train users have brought huge challenges to the high-speed train network capacity and user experience. In high-speed train scenario, user-centered services need to be considered to further improve the user experience of high-speed train users. The 5G-evolved high-speed train cell-free networking solution is proposed, which uses the cell-free network architecture to solve the problem of decreased user experience caused by handover and overlapping interference, build a user-centered network, and ensure high-speed train user experience.
