D3.1: Intermediate 5G V2X Radio (31.5.2018)
To meet the 5G V2X requirements, including the requirements on E2E latencies (below 5 ms), ultra-high reliability (99.999%), high density of connected vehicles and positioning accuracy (down to 5 cm), the 5GCAR radio interface design involves a rich set of technology components: 10 infrastructure-based (Task 3.1) and 9 sidelink-based technology components (T3.2). In addition, 5 technology components from Task 3.3 [link to D3.1 (pdf)]
