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.
