Description
The objective of this activity is to develop a testbed that allows the demonstration of vehicle-to-everything (V2X) 5G services viasatellite. Using existing satellite assets and on-ground antenna for mobile applications (not necessarily aesthetically attractive), the test bed shall address both forward and return link traffic, to support the definition of future V2X applications and associated technical enhancements. The set of services to be demonstrated shall be selected based on the space segment availability. Targeted Improvements:- Demonstrate the beneficial impacts of reusing 5G-based modems, network equipment, and other terrestrial technologies for V2X applications over satellite.- Demonstrate the end-to-end performance and service provision of this emerging vertical market.Description: 5G terrestrial networks will be deployed for enhancing traditional cellular broadband services, as well as for introducing new types of applications in emerging markets. Among those opportunities, an important growing sector is the automotive market (e.g., self-/assisted-driving, telemetry support and updates for vehicles), for which specific technologies are currently developed in 5G standardisation groups (identified as V2X) and very soon demonstrated in live trials. This market opportunity is enabled by the latest 5G Release 17 specifications, which support the introduction of Non-Terrestrial Networks (NTN), such as satellite systems. It is therefore proposed to assess in this activity how broadband GEO or NGSO systems could support the deployment of an integrated 5G network for V2X services. Each service is characterised by its own set of requirements (in terms of throughput, latency, coverage, reliability, security and/or interconnectivity). Some of these services could already be supported by existing space assets, therefore a suitable satellite use-case shall be identified: an existing satellite system, the necessary service link bandwidth, and relevant V2X services to be demonstrated. For this V2X showcase, the key on-ground technology elements to be procured and developed are the following as a minimum: the on-board car equipment (e.g. mobile antenna, 5G V2X chipsets), the terrestrial road-side units, the 5G base station, and the 5G core network. While it is expected to adopt existing COTS mobile antennas in the car, the V2X terminal, the base station, and the core network shall be enhanced to support NTN and V2X applications. The activity shall thus address the following points:a) Review the latest 3GPP specifications (i.e., 5G Release 17) regarding V2X and NTN applications;b) Propose V2X services and applications to be implemented and demonstrated over a satellite system (e.g., monitoring of vehicle data functions, up-to-date situational awareness for driving, software updates, emergency lights (V-16) etc.);c) Identify all necessary procurements (e.g., software and hardware) to first replicate a generic terrestrial 5G-V2X infrastructure;d) Describe the satellite use-cases covered by the selected network architecture and the associated technology developments;e) Procure, implement, and verify the proposed ground segment technologies, along with the necessary software developments;f) Integrate all components in the terrestrial-satellite hybrid network;g) Validation of 5G-V2X service performance via satellite;h) Propose a dissemination plan and live events forshowing the achieved 5G-V2X capabilities.
