Periodic Reporting for period 2 - ITN-5VC (Integrated Telematics for Next Generation 5G Vehicular Communications)

Reporting period: 2022-10-01 to 2025-01-31

Summary of the context and overall objectives of the project

The imminent need of deploying advanced communication and autonomous driving capabilities in vehicles is turning the race towards the realization of the so called fifth generation new radio (5G NR) networks into a real odyssey for the European automotive industry. The challenges arising from the coexistence of MIMO systems on vehicles, the growing number of sensors and radars and cooperative intelligent transport systems (C-ITS) in the realm of vehicle-toeverything (V2X) communications are piling up. Many of them have not been solved yet due to the lack of qualified personnel with joint expertise in communications and sensing technologies. Thus, the acute need of the proposed ITN-5VC project, a European Industrial Doctorate (EID) training network, arises.

ITN-5VC aims to investigate the key problems of the integration of multi-band multi-antenna communications, including mmWave, with radar heads and other wireless sensors into the same telematics unit, so that transmission chains and radiation systems were efficiently reused in a cost-efficient manner while delivering the required performance. Multiple antenna deployment, joint operation and performance of the resulting automotive solution will be investigated by 11 Early Stage Researchers (ESRs) working with top industrial manufacturers and academia in Europe. The training will tackle three main topics:
• Vehicular communications integrated with radar sensors for the sake of simplified telematics.
• Improved antenna and phased array technology deployment on the vehicle’s body or surface.
• Efficient protocol integration on V2X-specific system on chips for joint communication and sensing deployment on vehicles.
ITN-5VC will apply a new training Programme that follows the EU principles for Innovative Doctoral Training. Additionally, ITN-5VC training will apply short term missions, periodic challenges and an ECTS credit competition to boost the participation and engagement of the students to the Programme.

Work performed from the beginning of the project to the end of the period covered by the report and main results achieved so far

Here is a summary of the main accomplishments:
• The Project Management Committee organizes physical meetings once/twice a year and quarterly project meetings.
• The ESRs organize bi-monthly meetings to discuss their internal issues.
• All the ESRs worked according to their Career Development Plan.
• The network organized 8 training events, which are described in detail in the related section.
• The webpage, repository, social networks and teleconference tools were set up in the first year of the project.
• The project is visible on social media on Twitter, LinkedIn, and YouTube.
• Related to dissemination and communication activities, several communication and outreach actions were recorded, and a leaflet and a poster were designed to promote the project.
• 26 conference and journal papers have been published so far.
• All secondments were performed following the EID requirements

Regarding the exploitable results, based on the research carried out: BOSCH will refine AI-driven QoS prediction models to enhance V2X communication and autonomous driving while further developing sensing integration and heterogeneous RATs. Volkswagen (VW) will optimize vehicle antenna integration, improve V2X performance, and contribute to 5GAA and ETSI standardization. Gapwaves will explore antenna innovations for automotive radar applications and continue collaborating in joint communication and sensing. Fivecomm will enhance its 5G device portfolio, focusing on V2X sidelink communication for mobile robots, and plans to evolve towards ISAC-based solutions, reducing reliance on radar components.
