Testing certification in the C-V2X ecosystem

The growth of connected vehicles and infrastructure is becoming apparent throughout the world. C-V2X is constantly evolving, and it is necessary to ensure that all stakeholders (e.g. telecommunication and automotive sectors) are working together to ensure that connected mobility is safer and more efficient. Hence, it is important to ensure that the public and policy-makers trust the technology. 5GAA aims to support regional certification bodies to guarantee safe and reliable intelligent transport systems globally. 5GAA is dedicated to giving the C-V2X ecosystem players a voice in reviewing and developing the certification framework. On top of mandatory regulatory requirements (e.g. Radio Equipment Directive in the EU or FCC rules in the US), a number of organisations offer certification programs based on agreed industry standards which are equally critical to guarantee compliance and ensure interoperability. Such certification programs also facilitate global/regional harmonisation thus helping to reduce testing costs and accelerating time to market.

 

 

Ecosystem partner

The expertise of our members allows 5GAA to secure its position in the certification discussions in all parts of the world. 5GAA wants to continue supporting the organisations in the C-V2X ecosystem to ensure that the best products are placed on the market.

 

The article below and the linked document refer to an older version of the 5GAA roadmap, whose most updated version you can find here. 

Since the publication of the initial 5GAA roadmap in 2020, we have seen a growing deployment of connected safety services targeting traffic efficiency and safety. Over the past few years, revolutionary digital transformations have begun addressing some challenging mobility problems.

This new white paper synthesises a 5GAA vision of the future and develops the association’s forward-looking C-V2X roadmap in its latest version. It focuses on advanced driving use cases which pave the way to automated driving, teleoperation, automated valet parking, and sensor sharing – all of which contribute to global safety, mobility, environmental stewardship and transportation equity goals.

In the connected future of transportation, there will be an ever-growing set of cooperative Use Cases that need to be enabled in a standardised fashion. As the implementation of these Day 2+ Use Cases is different from the so far existing Use Cases, new information exchanges other than the currently existing beacon message structures will be required. To determine similarities and common mechanisms for this group of Use Cases, a definition was undertaken to provide a guideline in the field of such new Use Cases.

The term Complex Interaction was selected to describe Use Cases that require an exchange of sequential information with a minimum of three consecutive exchanges. If unique protocols and messages are to be developed for each individual Use Case, the amount of technical complexity would soon become unmanageable. Thus, it is vital to have a scalable framework for these Complex Interactions that covers common technical enablers.

Since so far no general requirements, descriptions and repeated behaviours have been identified for such Complex Interactions, the work introduced here presents an evaluation and representation of requirements which have been determined and developed during the analysis.

Malaga, 20 October 2022 – C-V2X technology revolutionizes the mobility ecosystem and how drivers interact with the world, making smart cars a reality today. These cars communicate with their surrounding infrastructure, be it other cars or vulnerable road users, while providing a better driving experience. 5GAA is at the forefront of redefining transportation, by providing real-time, reliable, and actionable information flows to enable safety, mobility, and environmental applications.

Sixteen 5GAA members gathered in Malaga on October 20 to showcase ready-to-deploy C-V2X technology and what the future has in store for the industry and vulnerable road user protection. Prominent members and partners of the 5GAA including 5GCroCo, Anritsu, Autotalks, Commsignia, Continental, Deutsche Telekom, Ericsson, Huawei, Intel, Keysight, Molex, Nokia, Rohde & Schwarz, Stellantis, Vodafone and Omniair demonstrated the current state of C-V2X and a wide range of applications for VRU (Vulnerable Road Users) protection, through a range of indoor and outdoor demos. The over 200 attendees included road operators, journalists from national and international media, and 5GAA delegates.

“C-V2X continues to drive the automotive transformation – and is now the new reality,” says 5GAA Chairman, Christoph Voigt. “Our key asset, the C-V2X technology, became an important part of the worldwide V2X ecosystem. The live demonstrations we have seen here, in Malaga, show us repeatedly that C-V2X is ready for a future where we can use our current infrastructure to improve protection for vulnerable road users.”

Using both direct and mobile network communications, the open-road demonstrations displayed the extensive capabilities of today’s C-V2X technology. To name a few:

• Protecting vulnerable road users and increasing the safety of cyclists on the road by alerting them of a collision
• Enabling smart intersections to enhance VRU safety by sending awareness messages to C-V2X-enabled cyclists
• Warning road users of traffic incidents between connected vehicles

The demonstrations were held at the DEKRA Test Track, a private field-testing area dedicated to connected & automated driving in Málaga, Spain. The test track reproduces multiple traffic situations using different V2X communications systems and networks, as well as traffic elements like traffic signs, traffic lights, road cones, pedestrians’ simulators that allow setting up various test cases. Located in a restricted area of 51.000 m2 (about twice the area of a parking space) with roundabouts, straight and curved roads, intersections, traffic lights and signalling, this connected & automated driving test track is a state-of-the-art facility that researches, develops, tests, and certifies the mobility of the future.

Together with our members, 5GAA has embraced digital transformation and is creating opportunities for transportation innovation. Its goal is to develop end-to-end solutions for future mobility that improve traffic efficiency, driving comfort and road safety to ensure a secure and sustainable transportation ecosystem.

The Predictive QoS and V2X Service Adaptation (PRESA) Work Item (WI) and this Technical Report (TR) enhance the framework for the analysis of the potential adaptations of V2X applications and V2X services when a QoS change (e.g. data rate degradation, reliability degradation, latency increase) is predicted and such information is provided to the application. The scope of this TR is to investigate the application and system reactions/adaptations, based on predicted changes of QoS. The methodology for the analysis of V2X use cases that use predictive QoS information is introduced in order to investigate various aspects, such as identifying interactions, QoS parameters of interest for prediction (e.g. downlink minimum data rate) for various use cases, related QoS prediction time horizons, thresholds for triggering prediction notification, etc.

This position paper outlines 5GAA’s core priorities in the field of space-based connectivity and industry requirements for the European Communication Satellite Constellation. We are motivated to highlight the important role that NTNs play in the development of both the automotive and telecommunications industries, and the wider deployment of connected and intelligent vehicles.

With the rapid development of the national economy, building a strong, safe, convenient, efficient, green, modern and comprehensive transportation system has become one of China’s key goals by 2035. To achieve this, the vehicle-to-everything (V2X) network will be a vital factor. Based on advanced ICT technologies, V2X will provide secure, intelligent, comfortable services by connecting vehicles, pedestrians and roads. Meanwhile, the laws and protocols governing intelligent vehicles, autonomous driving and V2X networks will also be developed in order to define each road user’s role and duty.
