AMAZING-6G proposes a novel set of 14 use cases in the domains of Healthcare, Public Safety, Energy and Transport (including Rail) which will be showcased in large-scale trials and pilots across Europe. Innovative technology enablers are planned to be developed and tested in the areas of Communications, Compute-as-a-Service, Applications and AI, IoT and localization. Security aspects will be taken into consideration in the development of solutions. Framed in this context, the significance of large-scale trials in B5G/6G networks lies not only in their ability to validate the technical capabilities of the technology but also in their capacity to unveil new use cases and applications that were previously inconceivable. As we move towards a world where the Internet of Things (IoT), augmented reality, and artificial intelligence play central roles in our daily lives, these trials provide a unique opportunity to explore the potential of B5G/6G in fostering innovative solutions across various sectors, from healthcare and transportation to utilities and public/environment safety. Through large-scale trials, stakeholders can gain valuable insights into the transformative power of B5G/6G networks and strategically position themselves to harness the full spectrum of opportunities that this cutting-edge technology offers.

EMPOWER-6G proposes a novel converged optical-wireless architecture that realizes an efficient 6G Cell-Free (CF)-based access network for high-density and high-coverage deployments. The proposed architecture takes full advantage of the distributed processing CF concept, as well as of wireless mmWave solutions, while being in-line with the O-RAN Alliance. Specifically, the EMPOWER-6G vision is based on the development of novel solutions at the radio access domain by enabling emerging CF technologies, while also contributing innovations at the optical transport domain and significantly evolving the MEC system towards fully elastic Edge Computing. The EMPOWER-6G network configuration deploys a distributed Edge infrastructure with Data Centres (DCs) structured in 2 tiers, featuring Radio Edge Regional Edge nodes, where the former DCs hosts the Network Functions of the (virtualized) RAN fully aligned with the O-RAN specifications, while the latter DCs host non-real-time network functions. Thus, EMPOWER-6G will shape a novel 6G network configuration by addressing challenges at the radio-edge, the regional-edge, and the network-management domains. At the radio-edge domain, EMPOWER-6G aims at designing novel CF networking mechanisms that will allow the significant scaling up of Radio Unit (RU) deployment in a cost-effective manner, by exploiting the application of the distributed processing CF concept, based on the disaggregation of the traditional CF Central Processing Unit (CPU) into Distributed Units (DUs) and a Central Unit (CU), in line with the 3GPP NG-RAN architecture. In parallel, EMPOWER-6G proposes an innovative mmWave Hybrid MIMO solution, with beam-steering and beam-sharing support. At the regional-edge domain, EMPOWER-6G aims at providing a new design for an optical regional edge network with FTTH support in order to achieve optimum functional splitting options, while also supporting novel control-plane protocols for CF networking support.

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.

6G is expected to emerge as key enabler for the intelligent digital society of 2030 and beyond, providing superior performance via groundbreaking access technologies, such as joint communication and sensing, cell-free, Radio Intelligent Surfaces, and ubiquitous wireless intelligence . Most importantly, 6G is expected to trigger a total rethink of network architecture design, which builds on the key idea of new stakeholders entering into the value chain of future networks. The SUNRISE-6G approach is inspired by the “network of networks” concept of 6G Networks, aiming to integrate all private and public infrastructures under a massively scalable internet-like architecture. SUNRISE-6G similarly aspires to create a federation of 6G test infrastructures in a pan-european facility that will support converged Testing as a Service (TaaS) workflows and tools, a unified catalogue of 6G enablers publicly accessible by experimenters, and cross-domain vertical application onboarding. Experimentation and vertical application onboarding are offered via a Tenant Web Portal, that acts as a single-entry point to the facility, serving end users (e.g., experimenters) and tenants (e.g., vertical developers, infrastructure owners, 6G component manufactures). The project execution is based on 4 pillars, delivering: (a) the Implementation of new 6G enablers, complementary to existing ones being developed in SNS Phase 1 projects, (b) A truly scalable and 3GPP compliant Federation solution that provides access to heterogeneous resources and devices from all Europe, (c) A Federated AI plane aligned with AIaaS and MLOPS paradigms, which promotes a collaborative approach to AI research which benefits immensely from scaling-up datasets and models and (d) a commonly adopted Experimentation Plane, which offers common workflows to experimenters.

EWOC project aims at developing a novel converged optical wireless network solution relying on a flexible, virtualizable infrastructure, required for full resource optimisation beyond 5G (B5G) requirements. Fundamental innovation will be sought through merging of the enabling concepts of optical layer virtualization, high frequency mm-wave transmission, multiple antenna technology, cell densification, terra-over-fiber (ToF) based femtocell connectivity and cloud radio access network (C- RAN) architecture. EWOC will aim at high capacity, low latency communications (40-90 GHz frequency), providing the basis for a 50-fold improvement over the 5G baseline. This necessitates development of novel, femto-cell technology, and seamless coexistence with first round legacy deployment. Such scenario also requires novel channel models and simulation methodologies to attain the desired trade-off between coverage, throughput and densification limits. EWOC will rely on fiber-optic deployment towards ToF connectivity, as an “added on feature” for the C-RAN architecture supporting resource management of versatile services with varying demands. Scenario compliant optical fronthaul virtualisation techniques, designed to provide cost effective beyond state-of-the-art resource optimisation, will be pursued through novel optical transceiver schemes and software defined network-based digital signal processing techniques. Research and training disciplines will serve as building blocks towards the scientific and socio-economic goals of increased capacity, coverage, flexibility, spectral efficiency, cost effectiveness, vendor agnosticism, and upgradability. EWOC provides a framework for promotion of such interdisciplinary innovation, with strong interoperability of models and methodologies from different disciplines. As such, EWOC training network is designed to foster opportunities for scientific and professional growth of ESRs from both topical and inter-disciplinary standpoints.
