  Millimeter wave (mmWave) is a practical solution to provide high data rate
for vehicle-to-everything (V2X) communications. This enables the future
autonomous vehicles to exchange big data with the base stations (BSs) such as
the velocity, and the location to enhance the safety for the advanced driving
assistance system (ADAS). To achieve this goal, we propose to develop a
situational rate map to characterize the distribution of the rates achieved
between the BSs and a uniform grid of vehicles. In this context, we consider a
mmWave 5G cellular system with two physical structures which are the
analog-only beamforming and hybrid precoding with limited feedback to
investigate the rate distribution for single and multiuser scenarios. We will
use the Ray-Tracing tool to construct the simulation environment and generate
the channels between the BSs and the grid of vehicles. Finally, we will study
the effects of the carrier frequency, the bandwidth, the BSs deployment, the
blockage, the codebook, the physical architectures and the number of served
users on the rate distribution maps. Moreover, we will present the rate
statistics to evaluate the coverage of served users for certain services
requirements and for various road shapes such as corners, intersections and
straightways.
