Description
The main outcome will be the availability of core technologies, architectures and protocols that can be indistinctly used for terrestrial or non-terrestrial networks for the provision of seamless services across an access and network fabric continuum overcoming the distinction between satellite and terrestrial access with seamless roaming capabilities between the two segments (beyond Hybrid network). It targets:
- Architectures and technologies requiring a very tight cooperation between the SNO and the MNO’s, towards a seamless TN-NTN communication continuum, and catering for a multiplicity of possible business models across the various domains.
- End to end service capabilities either through a TN segment or through an NTN segment, depending on relevant parameters including coverage, RT or NRT constraints, bandwidth and sustainability aspects.
- Innovative models such as managed multi tenancy of the space segment.
- Independent reconfiguration of the NTN part for performance, security and resilience optimisation.
- Compatibility with the most innovative use cases and their demanding requirements such as high rate Direct to Device, PPDR and other NTN specific use cases.
- Adaptability of the technologies, protocols and architecture (or a subset of those) to non-satellite scenarios such as drones or other flying 3D nodes.
The proposed Topic should cover R&I issues for low and medium TRL topics and plan, towards the end of the SNS implementation (i.e. later work programmes), for demonstration of critical technologies and applicability to specific use cases, e.g. with ESA partnership or national initiatives where possible, possibly using low-cost demonstrators such as Cubesat or equivalent EU offers.
Objective:Please refer to the "Specific Challenges and Objectives" section for Stream B-03 in the Work Programme, available under ‘Topic Conditions and Documents - Additional Documents’.
Scope:The scope of this topic focuses on the following areas:
- Management of multiple access networks through unified Control Plane capable of optimizing TN-NTN service provision according to traffic related parameters (QoS level, bandwidth, sustainability, latency, storage requirements...) and related RAN management, also accounting for very demanding use-case scenarios including public safety use-cases (e.g. PPDR) and system relying exclusively on satcom connectivity like aeronautic use cases.
- Management capabilities for independent reconfiguration of the NTN part for performance, security and resilience optimisation at system and subsystem level.
- Dynamic routing in multi-dimensional networks with selection of optimal paths for traffic, which is a key feature in leveraging the potential of NTN-TN unification and integration including optical links, improving (transport and mobility) protocols, flexible topology and traffic routing across such dynamic topologies with long-propagation link characteristics. For what concerns optical links (ISL) the approach is to consider them at system level characteristics and performance properties. However, development of specific technologies/subsystems for ISL is not in scope.
- Extension of a reference multi orbit constellation system(s) as evaluation framework for the assessment of routing and mobility schemes including various architectural splits. It should cover robustness of the scheme for disaster situation when TN is not available. The reference system may also address feasibility of the constellation considering spectrum usage from existing systems.
- Spectrum issues including i) novel schemes for dynamic spectrum access and sharing in FR3 (7 – 15 GHz possibly extended up to 24 GHz), providing good cost-coverage trade-off; ii) where applicable dynamic reuse of TN frequencies for NTN use where TN spectrum is not assigned or for very demanding scenarios including public safety use-cases.
- Multi tenancy and end to end resource slicing capabilities across multiple tenants, covering the space resources and including seamless mobility and handover between various segment, either TN to NTN or across 2 NTN infrastructures.
- Adaptability and versatility of the scheme to cover also non satellite 3D connected nodes and early system concepts (to be developed in subsequent phases) to provide GNSS free positioning with a better positioning accuracy/availability.
Notes: i) Specific satellite technologies such as advanced payloads and multi satellite generated antenna are not in scope from an in-depth R&I perspective. Their characteristics may be considered at system level where appropriate, but their detailed development is not part of the SNS JU WP objectives, ii) satellite architectures with different levels of data processing (e.g. transparent or regenerative space segments) are in scope.
Applicants should clearly identify the areas/priorities they address in case they only cover a subset.
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.
4. Financial and operational capacity and exclusion
General Annex C 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.
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.
