Feasibility study of 5G-based localization for assisted driving

Abstract

5G assisted driving applications demand the provision of centimetre-accurate positioning. Automated vehicles typically use several positioning systems, such as radars, cameras and sensors, in addition to Global Navigation Satellite Systems (GNSS). This is necessary to ensure integrity and reliability, as well as precise positioning. The deployment of 5G cellular networks along roads are envisaged to complement these existing technologies for assisted driving. Thus, this paper provides a feasibility study of the positioning capabilities for future 5G vehicle-to-infrastructure (V2I) networks, considering 5G-like multicarrier signals. Simulation results indicate achievable localization accuracies below 30 centimetres by using cellular ranging measurements with 50 and 100 MHz of system bandwidth.
