In this paper, we investigate wide-sense stationarity of a high- mobility propagation channel based on field measurement data analysis. The measurements were collected in an actual expressway at 28 GHz emulating for a typical vehicle-to-infrastructure scenario. During the measurements, a receiver was traveling at a speed up to 100 km/h and there were other moving vehicles in both directions that can impact on high Doppler shifts. To estimate a stationary distance defined as the distance where the channel can be considered wide-sense stationary, we applied the RUN test. Due to other moving vehicles, it is found that the range of stationary distance is 6-23 wavelengths in the expressway environment.
