Vehicular communication is characterized by diverse environments, high mobility of both the communicating entities and their surroundings, and comparatively low antenna heights on vehicles. These characteristics are very different from classical cellular cases and make the vehicular propagation and channel modeling particularly challenging. Additionally, the ultimate goal of next generation Vehicle-to-everything (V2X) communication systems is enabling accident-free cooperative automated driving. To achieve this goal, the communication system will need to enable a diverse set of use cases, which can result in channel conditions not fully explored in the past (e.g., blockage effects caused by densely packed platooning vehicles, communication between vehicles and vulnerable road users such as pedestrians and cyclists, etc.). Finally, in recent years, different frequency bands have been proposed for V2X communications (e.g., in centimeter wave bands, millimeter wave bands, and in visible light spectrum). The impact of frequency band and the propagation characteristics of high frequency (millimeter wave) V2X channels, etc. become very important objects of investigation.
