Operators and regulators keep 6G moving

6G news and analysis for the week ending Friday 10th July, 2026.

With the 3GPP working groups midway between their June and September plenaries, this was a quiet week for hard standards news, and the initiative passed to operators and regulators. Although to be honest, it has been a very quiet week. One shared theme emerged from two of the world’s larger operators. In Korea, KT committed around 18 trillion won, or 11.8 billion dollars, to reposition itself as an AI platform company. In Germany, Deutsche Telekom’s group technology chief argued publicly that 6G leadership must be won now, through standards and architecture, not at commercial launch. Both cast 6G as an AI-native infrastructure play rather than a standalone network upgrade.

The second theme is spectrum. Indonesia’s communications ministry warned that existing frequencies will not support 6G. It estimates each operator will need around 200 MHz, more than the largest block in its coming auctions. That adds a major Asia-Pacific market to the administrations positioning for upper mid-band spectrum ahead of WRC-27.

On standards, it is worth noting a Qualcomm recap (albeit an extremely extensive one) of June’s Singapore plenary, noting one incremental detail: confirmation of a third LDPC base graph for Release 21. We covered the plenary itself last month.

Saudi Arabia’s CST reopened its NTN research competition, and we again have four research papers for those who crave more detailed technical substance. They span open O-RAN test hardware, cell-free fronthaul design, waveform coexistence and satellite-powered control loops. A light week for news, but still a coherent one.

KT commits 18 trillion won to AI shift

KT will invest around 18 trillion won (11.8 billion dollars) to become an AI platform company, the operator announced on 6 July. The plan, reported by the Korea JoongAng Daily via Yonhap, was set out by chief executive Park Yoon-young at his first press conference since taking the role in March. Under its AX Platform Company initiative, KT will direct 12 trillion won into cybersecurity, IT and networks over three years, 5 trillion won into 1 GW of AI data centres, and 1 trillion won into new subsea cables. Securing leadership in next-generation networks, including 6G and satellites, sits within the networks area. The company framed the strategy around national ambition, stating the goal is for “Korea (to) emerge as a leading AI transformation, or AX, nation.”

• What’s new: The scale and the explicit AI-platform framing are the news here. KT, which chairs Korea’s AI Network Alliance (AINA), is casting itself less as a telco and more as an AI infrastructure provider. The 6G reference is brief and sits among much larger AI and cybersecurity commitments.

• Why this matters: KT is a bellwether for Korea’s coordinated 6G push, which we have tracked through AINA, the government’s three-year roadmap and multiple operator partnerships. The announcement confirms that Korean operators now frame 6G as one element of an AI-native infrastructure strategy. That framing matches the AI-RAN direction set out in the SK Telecom and NTT DOCOMO white papers. It also reflects the commercial reality that 6G revenue cases remain unproven, so operators anchor investment in assets with nearer-term returns.

• Implications for 6G standards: Operator capital flowing into AI data centres and compute strengthens the AI-native and cloud-native foundations that 6G architecture assumes. It does little, though, to advance specific Release 21 work items.

Deutsche Telekom argues 6G leadership starts now

Deutsche Telekom’s SVP Group Technology, Arash Ashouriha, has used a LinkedIn post to argue that 6G is not merely the next mobile generation but the foundational architecture of the AI-native era. Drawn from an internal Product and Technology Townhall, the post frames 6G as the convergence of communication, AI, sensing and compute into a single platform. His central claim is that leadership must be earned now, through the standards, architecture and spectrum decisions being taken today, not at commercial launch. He cited AI-RAN, non-terrestrial networks (NTN), sensing, Physical AI and DT’s 6G Innovation Hub in Berlin as signs of early movement. Ashouriha put it bluntly: “Leadership in 6G starts today. Not in 2029.”

• What’s new: The item is positioning rather than hard news, and we would normally set executive LinkedIn posts aside. But I’m including it because a) I know and respect Arash and b) it comes from the group technology lead at one of Europe’s largest operators and states a clear thesis: operators that build AI-native capability now will capture the value later. The post also drew engagement from Nokia Bell Labs and European research voices on closing the gap to Japan and Korea.

• Why this matters: The argument mirrors KT’s move in the same week, giving us two major operators, in Germany and Korea, framing 6G leadership as an AI-native and standards-shaping effort that begins years before launch. Deutsche Telekom is an influential voice in 3GPP RAN and SA and in European spectrum policy, so the posture matters if it converts into contributions and WRC-27 positions. The European sovereignty subtext is explicit, with the stated aim of shaping decisions rather than implementing those made elsewhere. The test, of course, is whether the Berlin hub and the AI-RAN and NTN work produce standards-relevant output.

• Implications for 6G standards: If DT channels this stance into concrete submissions on AI-native architecture and upper 6 GHz spectrum, it adds weight to those debates ahead of the September plenary and WRC-27. A LinkedIn post, though, is far from being a technical contribution.

Indonesia warns of 6G spectrum shortfall

Indonesia needs new frequency bands to support future 6G networks, according to the country’s Ministry of Communication and Digital Affairs. Speaking at a panel with the Indonesian Telematics Society (Mastel) in Jakarta, the ministry’s spectrum director Adis Alifiawan said existing allocations will not be enough. He estimated each operator will need roughly 200 MHz to run 6G services optimally. Yet the largest single block in the coming 700 MHz and 2.6 GHz auctions offers only about 190 MHz, with total mobile capacity projected to reach around 712 MHz. The remarks were reported by the state news agency ANTARA.

• What’s new: This is Indonesia’s clearest signal yet that it is planning spectrum specifically for 6G. The ministry is reviewing options including the upper 6 GHz band, a primary global 6G candidate ahead of the 2027 World Radiocommunication Conference. Alifiawan put it plainly: “We have to release new frequencies. Relying on existing frequencies will simply not be enough.”

• Why this matters: The 200 MHz-per-operator figure aligns with the requirement the GSMA and vendors have cited repeatedly, and which we covered in the January spectrum editions. Indonesia now joins a growing list of administrations positioning early for upper mid-band 6G spectrum. The gap between the 190 MHz on offer and the 200 MHz operators say they need illustrates the squeeze regulators face. It also supports the case that new bands, not refarmed ones, will carry early 6G capacity. These are ministry remarks, not a firm allocation, so treat the timeline with caution.

• Implications for 6G standards: National moves toward the upper 6 GHz band feed the FR3 (the 7 to 24 GHz range) planning that runs through Release 21. Wider per-operator allocations also shape the channel bandwidth assumptions that vendors design against.

CST launches third 6G NTN competition

Saudi Arabia’s Communications, Space and Technology Commission (CST) has launched the third edition of its Non-Terrestrial Networks (NTN) international research competition, run with the IEEE. The contest invites researchers, graduate students and recent PhD graduates to submit papers on NTN concepts for next-generation wireless and for integrating terrestrial and non-terrestrial networks. Submissions run through the EDAS platform until 10 August 2026. The top ten entries will present at the Global Space Connectivity and Sustainability Events in Riyadh.

• What’s new: The competition returns after two editions that together drew more than 80 papers from over 270 researchers across 47 countries. CST frames it within its wider effort to build an integrated, sustainable communications ecosystem.

• Why this matters: NTN integration from day one is one of the most consistent demands across the 3GPP 6G Workshop submissions, from Thales, ESA and others. Competitions like this seed the academic pipeline that feeds those standards debates. Saudi Arabia continues to use research funding and events to position itself in the 6G and space-connectivity conversation, alongside its Gulf neighbours. The initiative is promotional in nature, but the scale of past participation makes it a genuine channel for early NTN work.

• Implications for 6G standards: Well-supported NTN research can surface into 3GPP contributions through participating institutions. It adds to the international evidence base shaping Release 21 NTN work.

3GPP adds third LDPC base graph

Qualcomm’s Juan Montojo has published a device-maker’s summary of the June 2026 3GPP RAN plenary in Singapore. We covered that meeting in full at the time, including the Release 21 timeline, the December 2028 Stage 3 freeze and the March 2029 ASN.1 freeze, so we note this mainly for completeness.
The one incremental detail worth recording is confirmation of a third LDPC (low-density parity-check) base graph, known as BG3, for the data channel. It is intended to improve decoder efficiency at high data rates while leaving existing 5G deployments untouched. The blog also restates the baseline continuity from 5G, including multi-layer DFT-s-OFDM (Discrete Fourier Transform-Spread Orthogonal Frequency Division Multiplexing) in the uplink and up to 400 MHz channel bandwidth around 7 GHz. Both of those trace back to vendor positions at the March 2025 6G Workshop. For our fuller analysis, see the RAN #112 special report.

Selected research papers published this week

Open modular O-RAN testbed targets pre-6G

Fabian Göttsch and colleagues describe a modular, fully open O-RAN testbed that pairs Software Radio Systems’ open-source O-CU and O-DU, known as OCUDU, with an O-RAN-compliant radio unit from Massive Beams. It supports both the 7.2a functional split and a software-defined split 8, giving researchers full control across the central unit, distributed unit and radio unit for work ranging from 5G demonstrators to pre-6G experiments.

• Why this Matters: Open, low-cost reference platforms lower the barrier to practical 6G experimentation for academia and industry. OCUDU is the open O-CU/O-DU platform we have tracked since October 2025, and which underpins the US FutureG sensing prototype work. Tools like this help move 6G radio ideas from simulation into hardware validation.

Clos topologies suit cell-free 6G fronthaul

Max Franke and colleagues, including Giuseppe Caire, examine fronthaul network designs for cell-free MIMO, a leading candidate for the dense antenna deployments 6G will require. They find that simple tree topologies become infeasible as antenna counts rise, while a Clos topology, a scalable switching fabric, performs almost as well as the optimal design at scale.

• Why this Matters: Most cell-free research focuses on the physical layer, leaving the networking and transport side under-explored. This paper addresses the fronthaul feasibility that will determine whether cell-free MIMO, sometimes called Gothia Cell in 3GPP circles, is practical to deploy. It gives network planners concrete topology guidance for scaling these architectures.

RSMA lets OFDM and OTFS users coexist

Wafa Hedhly, Leila Musavian and Nikolaos Thomos propose a rate-splitting multiple access (RSMA) framework that lets OFDM and OTFS users share the downlink under mixed mobility conditions in 6G vehicular networks. Simulations show it beats conventional orthogonal multiplexing on outage probability and data rate, while accounting for channel estimation errors.

• Why this Matters: OFDM remains the 6G baseline but degrades under the high Doppler of vehicular scenarios, where orthogonal time frequency space (OTFS) performs better. Managing both user types on the same network is a practical coexistence problem for early 6G. RSMA offers a flexible way to handle that heterogeneity without splitting users onto separate systems.

Satellite power keeps 6G control loops running

Chengleyang Lei and colleagues study a system in which a satellite beams radio-frequency energy to power the sensing, communication and computing in industrial control loops, aimed at remote and post-disaster settings. They jointly optimise transmit power, bandwidth, computing capability and energy transfer to minimise control cost, and provide an iterative algorithm with supporting simulation results.

• Why this Matters: 6G is expected to support closed-loop robotic control, but battery limits constrain devices in remote areas. Combining non-terrestrial networks with wireless power transfer is an ambitious attempt to remove that constraint. The work is early and simulation-based, but it connects several 6G threads: NTN, energy harvesting and industrial control.
