The main outcome will be the availability of an evolvable 6G experimental infrastructure for the duration of the SNS programme that covers as many capabilities as possible to:

• Validate/demonstrate 6G candidate microelectronics technologies and systems as part of a representative end-to-end 6G architecture building on advanced components/HW technologies, Support where possible the development of synergies with 6G platforms developed in EU Member States (MSs) or Associated countries at national level in the context of 6G national R&I programmes, or other relevant industrial/research centre/academic activities.
• Exploit the results and momentum of the EC 5G Infrastructure PPP ICT-42 COREnect CSA project, which has defined a roadmap for Microelectronic components for telecom systems and reinforced synergies with the Chips JU.
• Integrate the solutions for the Radio Access part of the network, considering available solutions for future network implementation especially in the context of a future 6G disaggregated RAN and of the 6G convergence/virtualisation of data processing across the complete delivery chain, from RAN to data centre.
• Validate/demonstrate the performance of key 6G candidate HW solutions, technologies, components, and architectures operating across various frequency bands. To that extent, technologies as identified notably under previous or current 5G PPP, SNS and Chips JU projects may be considered as a baseline. Support to impactful contribution to standards is expected.
• Support integration of key 6G related Chips JU developments, though integration of wireless/processing advanced components, or compute platform/programmable accelerators within the 6G experimental platform.
• Validate/demonstrate feasibility of “better than 5G / 5G Advanced” KPIs, related indicatively to capacity, ubiquity, speed, latency, reliability, density of users, location accuracy, energy efficiency, security, service creation time, network management CAPEX/OPEX. It includes capability to incorporate emerging 6G specific KPIs and the capability to address key KVIs as appropriate as developed by previous 5G PPP and current SNS projects. Support the demonstration of the feasibility of key societal requirements and objectives such as energy reduction at both platform and use case levels, EMF impact and acceptability, sustainability, social inclusivity, safety and security, trust and resilience. Other key societal indicators include coverage, accessibility and affordability of the technology.

The main target is the development of new, or evolution of existing, experimental platform(s), where solutions from the microelectronics domain developed either in the context of Phase 1 SNS WP, or Horizon Europe Cluster 4 WP, or the Chips JU will be validated in terms of performance and applicability for 6G networks. Microelectronics developments in the context of 6G national initiatives are also in scope. The experimental platform(s) are expected to mainly focus on the Radio Access Network computing and communication capabilities (potentially including solutions covering a wide spectrum e.g., from cmWave up to THz) providing solutions in key areas identified by the COREnect CSA project.

The scope of the project should include one or more of the topics below:

• Advanced baseband capabilities as needed in virtualised platforms from the device or network side, taking open approaches and RISC-V technologies as targets and supporting SoC’s implementations as well as AI Edge modules, integration of multiple technologies for JCAS, Flexible hardware platforms supporting virtualisation and programmability in a fully distributed edge environment, including hardware accelerators. The project should clearly identify how potential computing infrastructure will be used to cater for the needs of the communication infrastructure.
• Integration of the THz communications technology into a complete THz communication chain and demonstrator, in view of validating the technology in an end-to-end radio system context, focusing on the two main THz communications applications: Integrated Access Backhaul (IAB) with high capacity provided to a myriad of small/nano cells; direct short range high-capacity access as needed in specific industrial environments.
• The system validation in this platform context which may address an E2E x-hauling demonstrator prototype with extended transmission reach at Sub-THz frequencies (>140GHz). The idea is to push the disruptive THz components developed previously to higher TRL levels and demonstrate their capabilities in D-band (140-164GHz) or above with extended performances such as power amplifiers reaching high power saturation while keeping low power consumption and low noise amplifiers (LNA) with low noise figure and high gain. In the context of industrialisation, the purpose will be also to showcase implementation of interconnected technologies in RFICs compatible with low RF loss at sub-THz frequencies operation.
• The potential inclusion of microelectronics solutions in the transport domain or unified solutions with NTNs and support of the IoT-connectivity-service provision value chain as appropriate.
• The establishment of a bridge between the SNS JU and the Chips JU, offering on the one hand new requirements to the microelectronics domain while on the other hand providing validation results of the tested solutions to Chips JU so that these can be considered in the subsequent phases of the Chips JU. The scope of the project targets an active cooperation link between the two communities and serve as a catalyst for further related activities for the EU private and public sectors. The scope also covers prominent downstream 6G standardisation activities by the microelectronics industries and stakeholders.

Evaluation of core 6G technologies and architectures in the context of specific 6G use cases may be considered but is not mandatory. Support of AI implementations through the considered microelectronics focus of the project shall include availability of large-scale data sets and training sequences as part of open repositories available to the EU community at large.

The demonstration capabilities of the target platform(s) are to be assessed against a set of emerging KPIs and KVIs as typically defined by the 6G international community and on-going initiatives. Proposals should be flexible enough to accommodate new relevant KPIs as they become available from the wider 6G community and from potential use cases.

To provide the required openness to host vertical use case pilots it is desirable that the project platform(s) support open framework principles (e.g., both legal and technical like open APIs) enabling future vertical projects to access and use them. It is also strongly desirable that these facilities are built in a way that allows the evaluation of competing technologies where appropriate. Openness is also a key requirement for “partial implementation” of demonstration capabilities. In that case, well defined infrastructure and service interfaces will have to be defined in view of interoperability with complementary platforms.

It is important to note that the applicants will commit that the project result will be easily replicated in the same or additional locations/countries if the project platform(s) will be selected for large scale trials as part of forthcoming Stream D projects.

The target experimental project platform(s) and their modules should be open and accessible for a long enough period to allow for an easy handover from one phase to the other. Conditions should allow experimental project platform(s) to be easily reused under fair and reasonable conditions for subsequent phases of the SNS programme implementation.

In view of ensuring maximum take up of the validated technologies, proposals should include a significant representation of key European industrial supply side players, in partnership with relevant academic, RTO, user actors, with strong demonstrated impact at standardisation level.
