Cooperative intelligent transport systems (ITS) and connected vehicles are foreseen to change the way mobility is conceived today. Cooperative and connected vehicles will lead to improved road traffic safety and efficiency and will also trigger innovation in the infotainment area. These will foster the design of disruptive new business models for both the telco and automotive industries, triggering a profound impact in society and economy. However, before this can become a reality, many technical challenges still need to be solved. One important challenge relates to the provision of efficient and reliable vehicle-to-anything (V2X) communications for the vehicles. The new emerging generation of mobile communications, the so-called 5G technology, is aimed at giving an answer to this challenge. Among other coordinated efforts, the European-funded 5GCAR project is looking into such V2X technology components and enablers. This paper aims at presenting and describing the technologies that are being considered in 5GCAR to make the vision of the cooperative and connected vehicle a reality.
