Description
- Optimized physical layer solutions and methods for an efficient, affordable, and accessible use of frequency spectrum, able to meet 6G technical KPIs and KVIs.
- Development of algorithms for massive MIMO systems for increased channel capacity and coverage improvements under difficult propagation conditions.
- An AI-native framework for RAN networks based on AI/ML and semantic technologies.
- Technologies and approaches for co-existence/sharing with other communication systems.
- Mechanisms and strategies to underpin automation and disaggregation in the RAN segment.
- Integration of function accelerators at the 6G RAN/compute continuum, where required.
- Algorithms, software and hardware implementations that can be eventually used for PoC and trials systems.
- Contributions to international standardisation.
Sustainability (from environmental, economic and societal perspectives) might be regarded as a horizontal aspect to be addressed by the aforementioned priorities, wherever possible. Developing technologies that will maximize system and equipment lifetime, thanks to modular, evolutive and flexible design that unlock the ability to adapt to new services, support new capabilities and satisfy 6G performance requirements is a relevant outcome.
Objective:Please refer to the "Specific Challenges and Objectives" section for Stream B-02 in the Work Programme, available under ‘Topic Conditions and Documents - Additional Documents’.
Scope:The scope of this topic focuses on the following areas:
- Physical layer technologies for enhanced spectral efficiency which includes energy-efficient new waveform design (featuring e.g., low PAPR, low complexity processing), backwards compatibility with existing CP-OFDM waveforms, or self-synchronizing modulation and waveform. Modulation and coding aspects are also in scope, including source-channel codes for short packet transmission, coding and caching for over-the-air computing in the network edge, or energy-efficient implementation of key physical-layer algorithms such as FEC or channel estimation. Asynchronous non-orthogonal multiple access schemes (e.g., NOMA, RSMA), advanced interference cancellation, advanced (full) duplexing strategies, or UE relaying can be considered, as well. Where relevant, RAN coordination (e.g., multi-TRP), improved lower layer signalling in 6G Air Interface, or physical-layer security aspects can also be addressed.
- Extreme exploitation of MIMO technologies, this including advanced massive MIMO technologies and extremely large antenna arrays (XL-MIMO) for increased network capacity and spectral efficiency and/or enhanced indoor coverage/localization; holographic beamforming and novel beam management schemes in massive MIMO settings leveraging on hybrid analog-digital front-end architectures; scalable, robust and low-complexity/overhead CSI acquisition strategies; massively distributed and cell-free MIMO technologies and architectures for improved coverage, reliability and mobility support and related synchronization, calibration and coordination aspects.
- AI/ML & semantic communications targeted at providing a native AI framework for RAN networks by using AI/ML for the lower layers of the protocol stack (e.g., including PHY, MAC and resource optimization), including AI-assisted multi-user and massive-MIMO systems channel coding aspects, the reduction of power consumption in the RAN or multi-modal model training (e.g., vision-assisted) for improved radio/network efficiency. Protocol learning, automated generation of lean, customizable neural radio protocol stacks, and learning networks, as well as related aspects such as distributed and centralized learning trade-offs, or conflict and anomaly detection and resolution are also in scope. This focus area notably includes semantic communications, or trustworthy/safe/explainable AI and the exploitation of generative AI for RAN optimization.
- Spectrum sharing and RAN co-existence focuses on aspects such as dynamic spectrum sharing between 5G and 6G, spectrum sharing and coexistence mechanisms to enable 6G in 7-15 GHz band, spectrum sharing and re-use for sustainability; overcoming limitations of variable numerology and, where deemed relevant, spectrum sharing with satellite, radar, or other terrestrial networks.
- Automation and disaggregation in the RAN segment: leveraging on open RAN architectures this area includes AI/ML powered automation and optimisation, micro-orchestration of RAN functions, programmable networks and API native, and exposure of network capabilities.
- Agile use of function accelerators at the 6G RAN/compute continuum which includes the integration of multi-processor SoC/accelerators, flexible and modular hardware/software architectures for communication-compute-control co-design, heterogeneous resource management, while meeting the new requirements and expectations on confidential computing solutions.
Note: Applicants may address a subset of the above priorities/areas. To facilitate the evaluation applicants should clearly identify the areas they are comprehensively addressing.
Eligibility & Conditions
General conditions
1. Admissibility Conditions: Proposal page limit and layout
General Annex A of the General Annexes to the Horizon Europe Work Programme 2023-2025 shall apply mutatis mutandis to the SNS call 2025 covered by this Work Programme, with the following derogations to page limits:
The limit for a full proposal is 70 pages for RIAs submitted under Stream B and C
2. Eligible Countries
described in Annex B of the Work Programme General Annexes with the following additional restrictions:
Restrictions on participation in accordance with Article 22(5) of the Horizon Europe Regulation
In order to achieve the expected outcomes, and safeguard the Union’s strategic assets, interests, autonomy, and security, it is important to avoid a situation of technological dependency on a non-EU source, in a global context that requires the EU to take action to build on its strengths, and to carefully assess and address any strategic weaknesses, vulnerabilities and high-risk dependencies which put at risk the attainment of its ambitions. For this reason, for proposals under topics identified as “subject to restrictions on participation in accordance with Article 22(5) of the Horizon Europe Regulation” (in the specific conditions for eligibility), participation is limited as follows: - For proposals under Stream B and Stream C, to legal entities established in Member States, Associated Countries, OECD and Mercosur countries.
In all topics, for the duly justified and exceptional reasons listed in the paragraph above, in order to guarantee the protection of the strategic interests of the Union and its Member States, entities established in an eligible country listed above, but which are directly or indirectly controlled by a non-eligible country or by a non-eligible country entity, may not participate in the action unless it can be demonstrated, by means of guarantees positively assessed by their eligible country of establishment, in so far this is a Member State or Associated Country, that their participation to the action would not negatively impact the Union’s strategic, assets, interests, autonomy, or security. Entities assessed as high-risk suppliers of mobile network communication equipment within the meaning of ‘restrictions for the protection of European communication networks’ (or entities fully or partially owned or controlled by a high-risk supplier) cannot submit guarantees. The guarantees shall in particular substantiate that, for the purpose of the action, measures are in place to ensure that:
a. control over the applicant legal entity is not exercised in a manner that retrains or restricts its ability to carry out the action and to deliver results, that imposes restrictions concerning its infrastructure, facilities, assets, resources, intellectual property or know-how needed for the purpose of the action, or that undermines its capabilities and standards necessary to carry out the action;
b. access by a non-eligible country or by a non-eligible country entity to sensitive information relating to the action is prevented; and the employees or other persons involved in the action have a national security clearance issued by an eligible country, where appropriate;
c. ownership of the intellectual property arising from, and the results of, the action remain within the recipient during and after completion of the action, are not subject to control or restrictions by non-eligible countries or non-eligible country entity, and are not exported outside the eligible countries, nor is access to them from outside the eligible countries granted, without the approval of the eligible country in which the legal entity is established.
Restrictions for the protection of European communication networks
These restrictions apply in accordance with General Annex B of the General Annexes of the Horizon Europe Work Programme 2023-2025: Entities that are assessed as high-risk suppliers of mobile network communication equipment within the meaning of ‘restrictions for the protection of European communication networks’ (or entities they fully or partially own or control) are not eligible to participate as beneficiaries, affiliated entities and associated partners.
Legal entities established in Russia, Belarus, or in non-government controlled territories of Ukraine
Given the illegal invasion of Ukraine by Russia and the involvement of Belarus, there is currently no appropriate context allowing the implementation of the actions foreseen in this programme with legal entities established in Russia, Belarus, or in non-government-controlled territories of Ukraine. Therefore, even where such entities are not subject to EU restrictive measures, such legal entities are not eligible to participate in any capacity. This includes participation as beneficiaries, affiliated entities, associated partners, third parties giving in-kind contributions, subcontractors or recipients of financial support to third parties (if any). Exceptions may be granted on a case-by-case basis for justified reasons. With specific regard to measures addressed to Russia, following the adoption of the Council Regulation (EU) 2024/1745 of 24 June 2024 (amending Council Regulation (EU) No 833/2014 of 31 July 2014), legal entities established outside Russia but whose proprietary rights are directly or indirectly owned for more than 50% by legal persons established in Russia are also not eligible to participate in any capacity.
3. Other Eligible Conditions
described in Annex B of the Work Programme General Annexes and with the following additional requirement:
Gender equality plans and gender dimension of R&I:
According to the General Annexes, provision of a gender equality plan for public bodies, research organisations or higher education establishments (including private research organisations and higher education establishments) applies as per Part B of the General Annexes to the Horizon Europe Work Programme 2023-2025.
Additional gender issues (related to award sub-criterion consideration of the gender dimension in research and innovation content) shall be addressed as appropriate in case research results are expected to differ when applied to different gender populations of users.

5a. Evaluation and award: Award criteria, scoring and thresholds
are described in Annex D of the Work Programme General Annexes.
Part D of the General Annexes to the Horizon Europe Work Programme 2025 shall apply mutatis mutandis to the SNS call 2025 covered by this Work Programme with the following complements:
The award criteria table is complemented as follows:
- Introduction in the impact section of a sub-criterion assessing the proposal contribution to the overall SME objective as appropriate;
- Introduction in the impact section of a sub-criterion assessing the proposal contribution to the IKOP objectives;
5b. Evaluation and award: Submission and evaluation processes
are described in Annex F of the Work Programme General Annexes and the Online Manual.
5c. Evaluation and award: Indicative timeline for evaluation and grant agreement
General Annex F of the General Annexes to the Horizon Europe Work Programme 2023-2025 shall apply mutatis mutandis to the SNS call 2025 covered by this Work Programme with the following amendments related to the procedure to rank proposals:
When two RIA proposals are equally ranked and that it has not been possible to separate them using first the coverage criterion, second the excellence criterion, and third the generic Impact criterion (i.e., after step 2 of the procedure outlined in part F of the General Annex), the level of SME participation will be taken as the next criterion to sort out the ties and if still un-conclusive, the level of IKOP will be considered as appropriate. If still inconclusive, the procedure outlined in part F of the General Annex will be resumed from step 3 onwards.
6. Legal and financial set-up of the grants
General Annex G of the General Annexes to the Horizon Europe Work Programme 2023-2025 shall apply mutatis mutandis to the SNS call 2025 covered by this Work Programme.
