6G news and analysis for the week ending Friday, 17th October, 2025.
This week brings a diverse set of developments that collectively illustrate how 6G is advancing on multiple fronts simultaneously — from deep technical architecture through to high-level international coordination.
The most technically substantive story comes from NVIDIA, which published a detailed technical blog on the distributed User Plane Function (dUPF) and its role in the AI-native 6G architecture. Building on last week’s AI-WIN coalition announcement, this post goes deeper into the specifics of how edge packet processing, accelerated by NVIDIA’s AI Aerial platform, could transform telecom networks into distributed AI infrastructure. The emphasis on ultra-low latency (as low as 25 microseconds) and co-location of AI inference at the network edge reinforces the vision of 6G as a compute-and-connectivity platform.
On the experimental front, e& UAE and NYU Abu Dhabi achieved 145 Gbps in what they describe as the Middle East’s first 6G terahertz trial. While THz frequencies remain firmly in the research domain for 6G, the trial validates propagation characteristics and hardware approaches that will inform future standardisation. In Europe, the European Space Agency and the EU’s SNS JU signed a collaboration agreement to integrate satellite and terrestrial infrastructure for 6G, directly addressing one of the most-discussed themes in the 3GPP 6G Workshop submissions.
Two broader industry stories round out the week: InterDigital and ABI Research published a report framing 3GPP Release 20 as the bridge between 5G-Advanced and 6G, while a coalition of global 6G research alliances issued the New Delhi Declaration, positioning 6G as “a global public good.”
NVIDIA details distributed UPF for 6G edge
NVIDIA published a technical blog detailing the distributed User Plane Function (dUPF) and its role in AI-native 6G networks. The dUPF brings user plane packet processing closer to the network edge, enabling ultra-low latency, high throughput and the co-location of AI inference workloads alongside connectivity functions. The post describes a reference implementation running on the NVIDIA AI Aerial platform using Grace Hopper hardware and BlueField-3 DPUs. Cisco’s Darin Kaufman, Head of Product for Mobility, said: “Software-defined DPU and GPU-accelerated edge infrastructure enable efficient deployment of Wireless RAN, Core, and AI applications.”
What’s new: The reference implementation achieves latency as low as 25 microseconds with zero packet loss using DOCA Flow hardware-accelerated packet steering. The dUPF is positioned as a key component of the AI-WIN full-stack architecture announced last week, alongside partners T-Mobile, MITRE, Cisco, ODC and Booz Allen Hamilton. The architecture co-locates dUPF with AI-RAN functions on shared NVIDIA hardware, enabling local breakout for AI traffic through dedicated AI-specific local data networks (AI-DN).
Why this matters: This moves the AI-WIN conversation from strategic positioning into concrete architecture. The dUPF concept is not new — it is defined in 3GPP’s 5G core architecture specifications — but NVIDIA’s implementation on GPU-accelerated edge infrastructure demonstrates how existing network functions can be repurposed for AI-native operations. The co-hosting of RAN, core and AI inference on shared hardware is central to the economic argument for 6G: operators need to reduce total cost of ownership while simultaneously supporting new AI-driven services. The use cases cited — video search and summarisation, AR/VR, autonomous vehicle communications — require the kind of sub-millisecond edge processing that centralised architectures cannot deliver.
Implications for 6G standards: The dUPF architecture aligns with the broader industry consensus that 6G will distribute compute across the network rather than centralise it. Multiple 3GPP 6G Workshop submissions, including from NVIDIA itself, argued for this compute-communication convergence. The question for standardisation is the degree to which AI workload orchestration at the edge becomes a specified network function versus an implementation choice left to vendors.

UAE claims first Middle East 6G terahertz trial
e& UAE and New York University (NYU) Abu Dhabi have jointly demonstrated what they describe as the first 6G terahertz (THz) pilot in the Middle East, achieving throughput of 145 Gbps. The trial validates the potential of THz frequencies for ultra-high-capacity, ultra-low-latency links. Marwan Bin Shaker, Acting Chief Technology and Information Officer at e& UAE, said: “Achieving 145 Gbps milestone is a breakthrough moment for the industry and for the UAE.” Prof. Murat Uysal, Founding Director of the Research Institute NYUAD Wireless Center, added: “This pilot provides critical validation of THz bands, considered a key enabler of 6G.”
What’s new: The partners also published a joint white paper, “Building the Fabric of 6G: Spectrum Frontiers and Enabling Technologies,” covering the strategic role of spectrum evolution from sub-7 GHz through to THz. The trial builds on a 6G Collaboration MoU signed earlier between the two organisations. The white paper highlights enabling technologies including AI-native networks, reconfigurable intelligent surfaces (RIS) and integrated sensing and communication (ISAC).
Why this matters: THz frequencies (broadly above 100 GHz) are being studied for 6G but face significant challenges including extreme propagation loss, hardware immaturity and processing demands. The ITU published a report earlier in 2025 on the technical feasibility of IMT in bands above 100 GHz, noting that fundamentally new system architectures will be required. This trial provides real-world performance data in the region, complementing earlier THz demonstrations from ETRI (200 Gbps at 160 GHz, covered in a previous edition) and Chinese research teams. The 145 Gbps figure is impressive but should be understood in the context of a controlled pilot rather than a deployable system.
Implications for 6G standards: THz bands are part of the broader spectrum discussion for 6G but are unlikely to feature in early commercial deployments. The more immediate standards impact is in the lower frequency ranges (upper 6 GHz, 7–24 GHz) where Release 20 study items are already active. THz research informs the longer-term standards roadmap and contributes to the ITU’s evaluation of candidate radio interface technologies for IMT-2030.

ESA and SNS JU partner on satellite-terrestrial 6G
The European Space Agency (ESA) and the EU-funded Smart Networks and Services Joint Undertaking (SNS JU) have signed a Memorandum of Understanding to collaborate on integrating terrestrial and satellite infrastructure for 6G. The partnership plans large-scale trials of 6G terrestrial and non-terrestrial connectivity for industries including utilities, agriculture and media. ESA director of connectivity and secure communications Laurent Jaffart said the organisation’s ambition is “to ensure that everyone is connected, everywhere and at all times.” SNS JU executive director Erzsebet Fitori described the collaboration as “an important step” toward “European technology sovereignty in 6G.”
What’s new: The MoU gives SNS JU project teams access to ESA ground and in-orbit laboratories and demonstration satellites. Joint activities will include large-scale trials designed to generate performance benchmarks and improve interoperability between satellite and terrestrial infrastructure. The partners also plan to pool expertise on 6G use cases in areas including edge computing.
Why this matters: Non-terrestrial network (NTN) integration was one of the most prominent themes at the 3GPP 6G Workshop in March 2025. Organisations including Airbus, ESA, Thales and China Satellite Network Group all called for satellite connectivity to be integrated into 6G from day one, rather than bolted on as an afterthought as happened with 5G NTN. The ESA-SNS JU collaboration provides a practical mechanism for generating the trial data and performance evidence that standards bodies will need. Europe’s positioning is significant given that both the US (through SpaceX and others) and China (through its rapidly expanding constellation programmes) are making major investments in satellite-terrestrial convergence.
Implications for 6G standards: NTN integration is already a major workload in 3GPP Release 20, including GNSS-independent positioning and system-level enhancements. The ESA-SNS JU trials could produce interoperability data that informs Release 21 specifications for native satellite-terrestrial convergence. The emphasis on European “technology sovereignty” also signals that NTN is becoming a geopolitical issue, not merely a technical one.

InterDigital frames Release 20 as 6G launchpad
InterDigital and ABI Research have published a report titled “The Bridge to 6G: Spotlight on 3GPP Release 20,” examining how this standards milestone consolidates 5G-Advanced while launching coordinated studies for 6G. Rajesh Pankaj, CTO at InterDigital, said: “Release 20 is the industry’s bridge between generations, leveraging a decade of 5G innovation and maturity into a launchpad for a smarter, more sustainable, and commercially viable 6G.” Dimitris Mavrakis, Senior Research Director at ABI Research, added: “6G is being shaped by a more diverse set of stakeholders.”
What’s new: The report identifies four key design areas in Release 20: AI-native networks with intelligence embedded across every layer; integrated sensing and communication (ISAC) enabling Sensing-as-a-Service; non-terrestrial networks solving deployment challenges for ubiquitous coverage; and sustainability targets of up to 100x greater energy efficiency per bit. The report highlights AI-enabled air interfaces and two-sided model training for tasks like CSI compression and predictive mobility management.
Why this matters: Release 20 is the inflection point where 5G-Advanced reaches commercial maturity and 6G study items begin in earnest. InterDigital is an active contributor to 3GPP, particularly in ISAC and AI-native RAN. The report’s framing of Release 20 as a “bridge” is accurate — the study items launched in this release will determine which technologies are carried forward into the normative 6G specifications of Release 21. The emphasis on a broader set of stakeholders shaping 6G, from hyperscalers to AI companies, reflects the expanding ecosystem that distinguishes 6G development from previous generations.
Implications for 6G standards: The Release 20 study items on ISAC, NTN and AI-native architectures are the foundation on which Release 21 normative work will be built. The outcome of these studies will determine whether 6G introduces fundamentally new capabilities or represents an incremental evolution of 5G-Advanced.

Global 6G alliances issue New Delhi Declaration
A coalition of international 6G research organisations issued a Joint Statement at the International Bharat 6G Symposium 2025, held alongside India Mobile Congress in New Delhi. Signatories include the Bharat 6G Alliance, 6G-IA (Europe), ATIS’ Next G Alliance (North America), Japan’s XGMF, South Korea’s 6G Forum, 6G Brasil, the UK-India Future Networks Initiative, UK TIN, the UK Federated Telecoms Hubs and Finland’s 6G Flagship. The declaration positions 6G as “a global public good.”
What’s new: The New Delhi Declaration establishes five guiding principles for 6G: trusted and secure, resilient and reliable, open and interoperable, inclusive and affordable, and sustainable and globally connected. The declaration calls for “trustworthy-by-design” networks with AI-native safeguards, open interfaces, multi-vendor interoperability and end-to-end global coverage through integrated terrestrial and non-terrestrial networks. It also emphasises skills development and capacity building across hardware, software and network standards.
Why this matters: This is the broadest multilateral 6G declaration to date, assembling representatives from virtually every major regional 6G initiative under a single set of principles. The breadth of signatories, spanning Asia, Europe, North and South America, distinguishes it from bilateral agreements. However, declarations of principle are not the same as technical contributions to standards bodies. The real test of this coordination will be whether it translates into aligned positions in 3GPP and ITU working groups. India’s TSDSI is a 3GPP Organisational Partner with 54 member companies, giving the host country a formal voice in standardisation.
Implications for 6G standards: The emphasis on “open and interoperable” aligns with the broader industry push for reduced optionality and simplified specifications that emerged from the 3GPP 6G Workshop. If the signatories coordinate their positions on contentious issues such as spectrum harmonisation and AI governance, the declaration could influence pre-standards consensus. For now, this is aspirational rather than technical.
