The large spectral channels at millimeter wave (mmWave) frequencies provide a means of achieving much higher data rates in vehicular communication systems. High data rates can be used for exchanging low-level sensing data (i.e., without much processing) or for infotainment applications to improve traffic safety and efficiency as well as user experience onboard. This monograph provides an overview of mmWave vehicular communication with an emphasis on results on channel measurements, the physical (PHY) layer, and the medium access control (MAC) layer. The main objective is to summarize key findings in each area, with special attention paid to identifying important topics of future research. In addition to surveying existing work, some new simulation results are also presented to give insights on the effect of directionality and blockage, which are the two distinguishing features of mmWave vehicular channels. A main conclusion of this monograph is that given the renewed interest in high rate vehicle connectivity, many challenges remain in the design of a mmWave vehicular network.
