High-Mobility Wireless Channel Measurements at 5.9 GHz in an Urban Environment
Next-generation intelligent transportation systems require a communication technology that can satisfy high demands in terms of latency and reliability. One of the promising communication technologies to satisfy such demands is the fifth-generation (5G) new radio (NR) for the vehicle-to-everything (V2X). To support the development of NR-V2X systems in the 5.9 GHz band, it is essential to perform channel measurements in high-mobility scenarios. High-mobility scenarios in the 5.9 GHz band have been well investigated through drive-by measurement campaigns. Although such measurements deliver real-world results, they do not allow for controlled experiments. To investigate propagation characteristics of the 5.9GHz band, we perform controllable and repeatable channel measurements at different velocities (25, 50, 100 and 125 km/h) in an urban environment. Furthermore, we compare measured wireless channels in terms of the normalized average local scattering function.
