The integration of satellite and terrestrial communication systems plays a vital role in the fifth‐generation mobile communication system (5G) for the ubiquitous coverage, reliable service, and flexible networking. Moreover, the millimeter wave (mmWave) communication with large bandwidth is a key enabler for 5G intelligent rail transportation. In this paper, the satellite‐terrestrial channel at 22.6 GHz is characterized for a typical high‐speed railway (HSR) environment. The three‐dimensional model of the railway scenario is reconstructed and imported into the Cloud Ray‐Tracing (CloudRT) simulation platform. Based on extensive ray‐tracing simulations, the channel for the terrestrial HSR system and the satellite‐terrestrial system with two weather conditions are characterized, and the interference between them are evaluated. The results of this paper can help for the design and evaluation for the satellite‐terrestrial communication system enabling future intelligent rail transportation.
