Abstract. The automobile industry is going through a transformative change and moving towards autonomous driving. Such autonomous cars will be equipped with several sensors such as radar, LIDAR etc. We will discuss the need for and the value of V2X communication in presence of such sensors, before addressing the benefit of V2X communication to enable and/or enhance autonomous driving. We will then present the current technologies and standards for V2X communication (WiFi-V2X and Cellular V2X), and introduce their roadmap. We will conclude with preliminary concepts of coexistence and market introduction.

Jérôme Härri is Associate Professor with the Communication Systems Department, EURECOM, Sophia Antipolis, France, where he leads the Connected Automated Transport System (CATS) team in the Networked Systems group. Previously, he led the Traffic Telematics Junior Research Group of the Institute of Telematics, Karlsruhe Institute of Technology, Karlsruhe, Germany. His research interests are related to wireless vehicular communication and networking, vehicular traffic flow modeling, positioning and localization, or control system optimization, in particular their mutual interactions in future ADAS and ITS. Jérôme has authored and coauthored over 70 international journal and conference papers, is involved in various national and European research projects related to connected vehicles, and actively contributes to various Standardization bodies. Jérôme Härri received the M.Sc. and the Dr. ès Sc. (PhD) degrees in telecommunication from the Swiss Institute of Technology (EPFL), Lausanne, Switzerland.

Shailesh Patil is a Principal Engineer/Manager at Qualcomm Incorporated. There he leads the C-V2X (Cellular V2X) research and 3GPP standardization group. Previously, he led the standardization of device to device communication in 3GPP LTE. This was for the very first time that device to device communication was standardized in any cellular standard. He has 43 granted patents and more than 80 pending patent applications. Shailesh Patil received his Masters and Ph.D. from University of Texas at Austin in 2004 and 2006 respectively.

Giuliana Zennaro took a degree in Electronic Engineering, in the sector of Industrial Automation Systems, University of Padova. She joined Centro Ricerche FIAT in 2006 and she has matured technical and management experience in a number of projects on cooperative systems, in-vehicle connectivity, smart device integration and evolution of vehicle access systems. She is currently leading in CRF the Connectivity Competence Centre, whose domain spans through all the wireless technologies & services related to the automotive domain. Besides she is the technical reference person for R&D area for the 5G Technology.
