On the New Needs and Requirements Arising from Connected and Automated Driving

Future 5G systems have set a goal to support mission-critical Vehicle-to-Everything (V2X) communications and contribute to an important step towards connected and automated driving. To achieve this goal, the communication technologies should be designed based on a solid understanding of the new V2X applications and the related requirements and challenges. In this regard, we provide a description of the main V2X application categories and their representative use cases selected based on an analysis of the future needs of cooperative and automated driving. We also present a methodology on how to derive the network related requirements from the automotive specific requirements. This is then used to analyze the key requirements of the selected use cases.
