  5G millimeter wave (mmWave) technology is envisioned to be an integral part
of next-generation vehicle-to-everything (V2X) networks and autonomous vehicles
due to its broad bandwidth, wide field of view sensing, and precise
localization capabilities. The reliability of mmWave links may be compromised
due to difficulties in beam alignment for mobile channels and due to blocking
effects between a mmWave transmitter and a receiver. In this paper, we study
the channel characteristics for mmWave and sub-6 GHz V2X communications using
ray-tracing simulations. We present results for time-varying path-loss, delay
spread, and angular spreads in the presence of a moving vehicle for
line-of-sight (LOS) and non-LOS (NLOS) trajectory, respectively. Additionally,
we study the effect of delay spread and angular spread when the base station
(BS) and user equipment (UE) are capable of adjusting the beam directions and
beamwidths dynamically. Finally, we explore the impact of blockage effects on
the quality of receive beams at 28 GHz for the considered vehicle trajectories.
