Abstract: The construction standards of conventional and high speed railways are different, and the coverage schemes of 5G-R are also different. Aiming at different scenarios such as conventional railway and high speed railway, this paper studies the networking scheme of 5G-R wireless access network in tunnel and non-tunnel areas along the railway lines, respectively analyzes the advantages and disadvantages of the two schemes with and without bridge, and proposes the scheme for reference for railway 5G-R network planning.

Key words: next generation railway dedicated mobile communication network, 5G-R, wireless access network, networking scheme
