From 3-5 September, the 6G‑REFERENCE project participated in URSI 2025 (XL Simposio Nacional de la Unión Científica Internacional de Radio), held in the Spanish city of Tarragona, organised by Universitat Rovira i Virgili. The project hosted a special session on “6G Systems and Integration of Communications and Sensing” on 3 September, chaired by researchers from our coordinator, Centre Tecnològic de Telecomunicacions de Catalunya (CTTC).
6G-REFERENCE’s Key Highlights at URSI 2025
In the special session (M.1.5: “6G Systems and Communications and Sensing Integration”), the project presented “6G‑REFERENCE Distributed Radio Specifications”, co-authored by by Zabdiel Brito‑Brito, Ignacio Llamas‑Garro, Jesús Salvador Velázquez‑González, Xavier Artiga, Guido Luzi and Riccardo Palamà from CTTC -you can download the publication from 6G-REFERENCE’s Zenodo.
The CTTC talk, chaired by the scientists Ignacio Llamas and Zabdiel Brito-Brito, gathered around 20 attendees, of whom 20% were researchers, being the remaining 80% students.
“It has been a great opportunity to connect with Spanish researchers and students working in the fields of Integrated Sensing and Communication (ISAC) and 6G Systems, which has made it possible to highlight the objectives set out in the 6G‑REFERENCE project, and find convergence in the efforts toward defining what 6G should be”, highlighted Zabdiel Brito‑Brito (CTTC).
Through this session, 6G‑REFERENCE was able to clarify its vision: communications and sensing not as separate domains, but as harmonised functions of future 6G networks. This aligns with the project’s work on hardware enablers for cell‑free coherent communications and sensing across urban environments.
About URSI 2025: XL Simposio Nacional de la Unión Científica Internacional de Radio
URSI 2025, XL Simposio Nacional de la Unión Científica Internacional de Radio, served as a prime forum for the exchange of ideas between academia, students, and practitioners in the Information and Communication Technology (ICT) sector. For 6G‑REFERENCE, the session offered:
-
A chance to present its technical specifications for distributed radio systems.
-
A platform to engage with early‑career researchers, which may help foster future collaborations.
-
Visibility for the integrated sensing and communications (ISAC) paradigm, reinforcing its importance in shaping 6G research agendas.
Since 1980, URSI has been the leading technical forum for researchers, companies, and technologists in the ICT sector and the main annual event of the Spanish National Committee of URSI. It annually brings together researchers, professionals, and students in the field of Information and Communications Technologies to present their research and technological development work.
In addition to being an excellent opportunity for emerging researchers, the conference provides a platform for debate, exchange of experiences, and opportunities for collaboration among the various working groups in the ICT areas of engineering and experimental sciences, as well as among them and industry.
6G-REFERENCE’s Next Event: European Microwave Week (EuMW 2025)
Following URSI, 6G‑REFERENCE will continue disseminating its research at European Microwave Week (EuMW 2025) in Utrecht (The Netherlands) on 21-26 September. At EuMW, 6G‑REFERENCE will present its innovative paper titled: “Planar Low‑Cost Microwave Ring Resonator Temperature Sensor using a PDMS Active Layer”, on Thursday 25 September at 11:30h at EuMC49-3.
As the journey towards 6G continues, events like URSI 2025 and EuMW 2025 provide a vital platform for collaboration, knowledge exchange, and community building. The 6G‑REFERENCE project remains committed to advancing the integration of communications and sensing technologies, laying the groundwork for a more intelligent and connected future in urban areas.
