- Abstract
- LTE-R (Long Term Evolution Railway) communication problems occur due to high-speed trains, structures around railway tracks, and tunnels. To solve this problem, various studies such as dual system construction and multi-pass are being conducted. However, problems such as cost increase and the occurrence of blockage areas remain issues to be resolved. To solve this problem, in this paper, we intend to apply the IAB (Integrated Access and Backhaul) technology discussed in The 3rd Generation Partnership Project (3GPP) standard to the railway wireless communication network. By installing an IAB node in an area where communication failure is expected, it is possible to provide a stable train communication environment by supplementing the communication failure problem through relay communication between the train and the IAB node.
