5G-ROUTES: D5.9 Report on standardisation activities and spectrum allocation recommendations

This report provides 5G-ROUTES initial analysis of Connected and Automated Mobility (CAM) standards and 5GROUTES plan for standardisation activities for CAM services and associated technical enablers. The recommendations for spectrum allocation are also provided based on current discussions at the European level. The connected and automated mobility represents an ecosystem of technology to address the connectivity on mobile platform for higher value service, including connected and automated driving, passenger connectivity, vehicles controls, and many other applications and use cases. CAM services analysis drives to the identification of requirements such as interoperability, flexibility, interconnection, high system capacity, wide service area coverage, higher throughput, and reduced latency among others. These requirements are covered by CAM technical enablers mainly based on communication networks assets: edge computing, session/service continuity, integrated network management and orchestration, QoS prediction, vehicles message routing, etc. Several standards development organisations (SDOs) are identified as appropriate fora to discuss applicable standards for CAM services and associated technical enablers. These include the International Telecommunication Union for the spectrum allocation aspects, the European Telecommunications Standards Institute (ETSI) for the standard applicable to CAM technical enablers (e.g. MEC, V2X), 3GPP for the support of CAM by the 5G network, C-ROADS for a common European platform for Cooperative Intelligent Transport Systems (C-ITS) and many others. The preliminary gap analysis shows that work is already performed in ETSI on CAM messages and service specifications. However, key aspects necessary for the support CAM services on 5G networks are still to be defined. Hence, the integration of Multi-access Edge Computing (MEC) into CAM standards and the standardisation of information protocols (e.g. for communication between vehicles and network) are identified as the next steps in 5G-CAM standardisation. 5G-ROUTES will work with the relevant standardisation organisations to align 5G-ROUTES ambitions and developments to the existing standards and contribute to their evolution. 5G-ROUTES standardisation approach will consist on 4 following phases: Phase1 – Standardisation needs: to collect all the standardisation requirements with respect to the project ambitions Phase 2 – Standardisation roadmap: to establish 5G-ROUTES roadmap of standardisation activities Phase 3 – Standardisation activities: to execute the standardisation activities as planned in phase 2 Phase 4 – Report on standardisation activities: to report 5G-ROUTES achievement in standards at the end of the project. Finally, spectrum allocation is another challenge for CAM services, in particular in the cross-board context where the neighbouring countries can have different spectrum regulations. It is necessary in this particular context to agree on the same spectrum allocation. The current discussions on this area focus on 5.9 GHz band for V2X. Some frequency allocations are therefore already proposed for roads ITS and rails ITS. 5G-ROUTES will analyse the available options and provide spectrum allocation recommendations for CAM service. This report provides the initial roadmap for the project standardisation activities. A second publicly available deliverable will be produced 31st May 2023 and will provide 5G-ROUTES standardisation activities report
