One of the key research directions to increase thecapacity of new radio (NR) vehicle-to-everything (V2X) commu-nication systems is extension of employed frequency bands fromsub-6 GHz to millimeter wave (mmWave) range. To investigatedifferent propagation effects between sub-6 GHz and mmWavebands in high-mobility scenarios, one needs to conduct channelmeasurements in both frequency bands. Using a suitable testbedsetup to compare these two bands in a fair manner, we performchannel measurements at center frequencies of 2.55 GHz and25.5 GHz, velocities of 50 km/h and 100 km/h, and at 126 differentspatial positions. Furthermore, we conduct a comparative studyof the multi-band propagation based on measurement results. Weestimate the power delay profile (PDP) and the Doppler powerspectral density (DSD) from a large set of measurements collectedin a measurement campaign. Finally, we compare measuredwireless channels at the two employed frequency bands in termsof root-mean-square (RMS) delay spread and RMS Dopplerspread.
