The vehicular-to-everything (V2X) technologies are regarded as key technologies for vehicles to communicate with each other and everything around them in order to support the introduction of intelligent transport systems (ITS) as well as new capabilities for cooperative, connected and automated mobility (CCAM). As an interactive communication system, V2X complements the capabilities of other autonomous driving assistance system (ADAS) sensors. While traditionally, the IEEE 802.11p standard provided the foundation for basic safety applications, the new cellular V2X (C-V2X) standard established by the 3rd Generation Partnership Project (3GPP) has shown to provide improved range and reliability for enhanced safety services. The C-V2X basic functionality is already defined in 3GPP Rel. 14. Its full potential can be exploited with 5G New Radio (NR) technologies which will be introduced from 3GPP Rel 16 onwards. In this paper, we review the current C-V2X technology and provide some outlook into envisioned use cases employing 5G NR, like perception and intention sharing as well as additional innovations that can be expected from connected cars.
