Vehicular Communications in the B5G Era

In this chapter, the requirements and challenges in the design and analysis of advanced wireless communication systems for vehicular communications (from V2V to V2X) will be presented. The characteristics and challenges in wireless channel behavior will be described, from RF-mmWave to future THz frequency bands. Different types of vehicular network configurations, in terms of antenna subsystems and transceivers, will be described, as well as in relation with the impact of dense urban and urban and rural scenarios on system implementation. Examples of coverage/capacity relations for vehicular communication scenarios will be presented, based on volumetric geometric/stochastic modeling techniques. Future beyond 5G (B5G) network architectures, as the evolution of present 5G networks, and current developments will be presented. The role of the satellite segment in the future of B5G vehicular communications will be outlined.
