Millimeter wave (mmWave) is a practical solution to provide high data ratefor vehicle-to-everything (V2X) communications. This enables the futureautonomous vehicles to exchange big data with the base stations (BSs) such asthe velocity, and the location to enhance the safety for the advanced drivingassistance system (ADAS). To achieve this goal, we propose to develop asituational rate map to characterize the distribution of the rates achievedbetween the BSs and a uniform grid of vehicles. In this context, we consider ammWave 5G cellular system with two physical structures which are theanalog-only beamforming and hybrid precoding with limited feedback toinvestigate the rate distribution for single and multiuser scenarios. We willuse the Ray-Tracing tool to construct the simulation environment and generatethe channels between the BSs and the grid of vehicles. Finally, we will studythe effects of the carrier frequency, the bandwidth, the BSs deployment, theblockage, the codebook, the physical architectures and the number of servedusers on the rate distribution maps. Moreover, we will present the ratestatistics to evaluate the coverage of served users for certain servicesrequirements and for various road shapes such as corners, intersections andstraightways.
