Abstract

The International Union of Railways has decided to migrate railway communication technology from being GSM-based to LTE-based or LTE-R. As a leading country in LTE space, South Korea will launch the train control system based on LTE by 2016. To ensure the most reliable train operation in this system, a fully duplicated network structure with overlaid radio cells is needed. Existing methods and results often rely on a single network structure setup. Thus, in this paper, we introduce the design of an LTE-R train control communication with a duplicated network structure. We propose two different network structures with fully-overlapping cell arrangement and with partly overlapping cell arrangement, respectively for the system and discuss major problems, including handover and inter-cell interference.
