6G-BRICKS: Building Reusable testbed Infrastructures for validating Cloud-to-device breaKthrough technologieS (6G-BRICKS)

6G networks, currently only existing as concepts, are envisioned as portals to a fully digitized society, where the physical and virtual world are blended via boundless Extended Reality (XR), and also as an enabler for the Digital and Green transformation of the European Industries. To support this vision, the network capacity must be increased at least by an order of magnitude, while infrastructures must be transformed into a very dense continuum. Thus, academia and industry have shifted their attention to the investigation of a new generation of Smart Networks and infrastructures. It is clear that to win this race towards shaping the next-generation communication ecosystem, a new generation of testbed infrastructures and breakthrough research and technology development is needed needed, as well as a new generation of testbeds to support future research initiative. To this end, 6G-BRICKS aims to deliver a new 6G facility, building on the baseline of mature ICT-52 platforms, that bring breakthrough cell-free and RIS technologies that have shown promise for beyond 5G networks. Moreover, novel unified control paradigms based on Explainable AI and Machine Reasoning are explored. All enablers will be delivered in the form of reusable components with open APIs, termed “bricks“. Finally, initial integrations with O-RAN are performed, aiming for the future-proofing and interoperability of 6G-BRICKS outcomes.
