Draft new ITU-R recommendation (not yet approved): M.[IMT.FRAMEWORK FOR 2030 AND BEYOND]
Introduction:
At its 44th meeting in June 2023, ITU-R WP 5D finalized development of a draft new Recommendation ITU-R M.[IMT.FRAMEWORK FOR 2030 AND BEYOND] on “Framework and overall objectives of the future development of IMT for 2030 and beyond.” This draft recommendation is expected to be approved by year end 2023.
With the evolution of information and communications technologies, IMT-2030 is expected to support enriched and immersive experience, enhanced ubiquitous coverage, and enable new forms of collaboration. Furthermore, IMT-2030 is envisaged to support expanded and new usage scenarios compared to those of IMT-2020, while providing enhanced and new capabilities.
The objective of this Recommendation is to provide guidelines on the framework and overall objectives of the future development of IMT-2030 (aka “6G”).
In the next three years starting from 2024, ITU-R WP 5D will focus on the study of detailed technical performance requirements and the evaluation criteria and methodologies, paving the way for the technology proposal evaluation in the last phase of the IMT-2030 cycle, i.e. from 2027 to 2030.
Relationship between ITU-R (WP 5D) and 3GPP:
ITU-R WP 5D establishes the overall research and development direction, key performance indicators, as well as the standardization, commercialization, and spectrum roadmap for the new generation of IMT through a Framework Recommendation. It then moves on to defining the technical performance requirements to achieve the Framework.
After that, 3GPP develops detailed technical specifications that meet the requirements defined by the ITU-R recommendations and submits their specs to ITU-R WP5D (via ATIS) as a candidate radio interface technology. 5D then evaluates whether the 3GPP defined technology meets the requirements of the ITU-R (for 5G and presumably for 6G too). If it passes the evaluation process, it is approved as ITU-R Recommendation.
Figure 1. below shows these relationships:
Figure 1. Relationship between ITU-R and 3GPP
………………………………………………………………………………………………………………………….
Motivation and societal considerations:
The motivation for the development of IMT-2030 is to continue to build an inclusive information society and to support the UN’s sustainable development goals (SDGs). To this end, IMT-2030 is expected to be an important enabler for achieving the following goals, among others:
– Inclusivity: Bridging digital divides, to the maximum extent feasible, by ensuring access to meaningful connectivity to everyone.
– Ubiquitous connectivity: To connect unconnected, IMT-2030 is expected to include affordable connectivity and, at minimum, basic broadband services with extended coverage, including sparsely populated areas.
– Sustainability: Sustainability refers to the principle of ensuring that today’s actions do not limit the range of economic, social, and environmental options to future generations. IMT-2030 is envisaged to be built on energy efficiency, low power consumption technologies, reducing greenhouse gas emissions and use of resources under the circular economy model, in order to address climate change and contribute towards the achievement of current and future sustainable development goals.
– Innovation: Fostering innovation with technologies that facilitate connectivity, productivity and the efficient management of resources. These technological advances will improve user experience and positively transform economies and lives everywhere.
– Enhanced security, privacy and resilience: The future IMT system is expected to be secure and privacy-preserving by design. It is expected to have the ability to continue operating during and quickly recover from a disruptive event, whether natural or man-made. Making security, privacy and resilience key considerations in the design, deployment and operation of IMT-2030 systems is fundamental to achieving broader societal and economic goals.
– Standardization and interoperability: To achieve wide industry support for IMT 2030, future IMT systems are expected to be designed from the start to use transparently and member-inclusively standardized and interoperable interfaces, ensuring that different parts of the network, whether from the same or different vendors, work together as a fully functional system.
– Interworking: IMT-2030 is expected to support service continuity and provide flexibility to users via close interworking with non-terrestrial network implementations, existing IMT systems and other non-IMT access systems. IMT-2030 is also expected to support smooth migration from existing IMT systems, where including support of connectivity to IMT-2020 and potentially IMT-Advanced devices will be advantageous for inclusivity.
User and application trends:
Applications and services enabled by IMT-2030 are expected to connect humans, machines and various other things together. With the advances in human-machine interfaces, interactive and high-resolution video systems such as extended reality (XR) displays, haptic sensors and actuators, and/or multi-sensory (auditory, visual, haptic or gesture) interfaces, IMT-2030 is expected to offer humans immersive experiences that are virtually generated or happening remotely. On the other hand, machines are envisaged to be intelligent, autonomous, responsive, and precise due to advances in machine perception, robotics, and artificial intelligence (AI). In the physical world, humans and machines are expected to continuously interact with each other, working with a digital world that extends the real world by using a large number of advanced sensors and AI. Such a digital world not only replicates but also affects the real world by providing virtual experiences to humans, and computation and control to machines.
IMT-2030 is expected to integrate sensing and AI-related capabilities into communication and serve as a fundamental infrastructure to enable new user and application trends. From these trends, it is expected that IMT-2030 provides a wide range of use cases while continuing to provide, inter alia, direct voice support as an essential communication. Furthermore, IMT-2030 technology is expected to drive the next wave of digital economic growth, as well as sustainable far-reaching societal changes, digital equality and universal connectivity. IMT-2030 is expected to further enhance security, privacy, and resilience.

Technology trends:
Report ITU-R M.2516 provides a broad view of future technical aspects of terrestrial IMT systems considering the timeframe up to 2030 and beyond, characterized with respect to key emerging services, applications trends, and relevant driving factors. It comprises a toolbox of technological enablers for terrestrial IMT systems, including the evolution of IMT through advances in technology and their deployment. In the following sub-sections, a brief overview of emerging technology trends and enablers, technologies to enhance the radio interface, and technologies to enhance the radio network are presented.
Emerging technology trends and enablers:
IMT-2030 is expected to consider an AI-native new air interface that uses AI to enhance the performance of radio interface functions such as symbol detection/decoding, channel estimation etc. An AI-native radio network would enable automated and intelligent networking services such as intelligent data perception, supply of on-demand capability etc. Radio networks that support AI services would be fundamental to the design of IMT technologies to serve various AI applications, and the proposed directions include on-demand uplink/sidelink-centric, deep edge, and distributed machine learning including federated learning.
The integration of sensing and communication functions in IMT-2030 systems would give new capabilities, enable innovative services and applications, and provide solutions with a higher degree of sensing accuracy. It would lead to benefits in enhancing performance and reducing overall cost, size, and power consumption of both systems, when it is combined with technologies such as AI, network cooperation, and multi-nodes cooperative sensing.
Computing services and data services are expected to become an integral component of the IMT 2030 system. It is expected to include processing data at the network edge close to the data source for real-time responses, low data transport costs, high energy efficiency and privacy protection, as well as scaling out device computing capability for advanced application computing workloads.
Device-to-device wireless communication with extremely high throughput, ultra-accuracy positioning and low latency would be an important communication paradigm for IMT-2030. Technologies such as THz technology, ultra-accuracy sidelink positioning, and enhanced terminal power reduction can be considered to support new applications.
Typical use cases for the 6 usage scenarios of IMT-2030:
| Immersive Communication |
|
| Massive Communication |
|
| Hyper Reliable & Low-Latency Communication |
|
| Ubiquitous Connectivity |
|
| Integrated AI and Communication |
|
| Integrated Sensing and Communication |
|

The Figure below summarizes the different dimensions of capabilities for IMT-2030, including 9 enhanced capabilities (peak data rate, user experienced data rate, spectrum efficiency, area traffic capacity, connection density, mobility, latency, reliability, and security/privacy/resilience) and 6 new capabilities (coverage, positioning, sensing-related capabilities, AI-related capabilities, sustainability, and interoperability). The range of values for the capabilities in the figure are estimated targets for research and investigation of IMT-2030. For each usage scenario, single or multiple values within the range would be developed in the future in other ITU-R Recommendations/Reports.

IMT-2030 envisages the use of a wide range of frequency bands ranging from sub-1 GHz up to sub-THz bands (low bands, mid bands (centimeterWave), mmWave bands and sub-THz bands). It expects that wider channel bandwidths may be needed to support future applications and services for IMT-2030 in a wide variety of deployments, including wide-area deployments. It is important to ensure that the current spectrum and newly assigned spectrum are harmonized.

New ITU report in progress: Technical feasibility of IMT in bands above 100 GHz (92 GHz and 400 GHz)
Introduction:
ITU-R Report R M.2376 contains studies of frequency ranges (6-100 GHz) for International Mobile Telecommunications (IMT) technologies. It is envisioned that future IMT systems will need to support very high throughput data links to cope with the growth of the data traffic, new extremely bandwidth demanding use cases, as well as new capabilities of integrated sensing and communication (ISAC). There has been academic and industry research and development ongoing related to suitability of mobile broadband systems in frequency bands above 92 GHz to enable services requiring tera-bit per second speeds. This has prompted researchers to consider the technical feasibility of higher frequency bands in IMT.
Overview:
This ITU-R preliminary draft new report in progress provides information on the technical feasibility of IMT in bands between 92 GHz and 400 GHz. This Report complements the studies carried in Report ITU-R M.2376. This technical feasibility Report includes information on propagation mechanisms and channel models, as well as newly developed technology enablers such as active and passive components, antenna techniques, deployment architectures, and the results of simulations and performance tests. Aspects of coexistence with incumbent radiocommunications services above 92 GHz are outside the scope of this document, and this report does not presuppose the inclusion of any item on a future World Radio Conference (WRC) agenda nor the decisions of a future WRC.
ITU-R WP5D emphasizes that the further development of the draft new Report ITU-R M.[IMT.ABOVE 100GHz] does not contain propagation prediction methods. It contains only results contributed by industry and academia of propagation measurements and simulation campaigns.
…………………………………………………………………………………………………………………………
From: Experiments bring hope for 6G above 100 GHz:
Channel models for 4G and 5G cannot simply be extended above 100 GHz; engineers must verify and fine-tune knowledge to correctly reflect the impact of the environment for various use cases. We must, for example, understand outdoor scenarios and indoor industrial scenarios where human bodies, vehicles, and environmental conditions such as rain propagation strongly influence signal propagation.
5G pioneered the use of millimeter wave frequencies with bandwidths up to 400 MHz per component carrier to enable transmission rates necessary for demanding real-time applications such as wireless factory automation. 6G technology is aiming at significantly higher transmission rates and lower latencies. Large contiguous frequency ranges for ultra-high data rates with bandwidths of several GHz are only available above 100 GHz.
With sonar, the transmitter and receiver are in the same place. As for channel sounding of electromagnetic waves, the transmitter and receiver are spatially separated. In time domain channel sounding, a modulated pulse signal with excellent autocorrelation properties, such as a Frank-Zadoff-Chu (FZC) sequence [1], serves as a “ping” whose channel impulse response (CIR) is recorded. This propagation-time measurement is very similar to the time-delay measurements performed in a GPS receiver in reference to the GPS satellites (and subsequently inferring the position information), where each satellite transmits its specific correlation sequence. The CIR includes both the direct propagation components (line of sight, LOS) and all reflection and scattering components (non-line-of-sight, NLOS) from objects in the environment (Figure 1). We can derive channel-model parameters and their values from the results.
Figure 1. Operating principle of time domain channel sounding: The channel impulse response (CIR) is measured by emitting an electromagnetic “ping” at the frequency of interest and capturing all returning signal components.

Samsung-Mediatek 5G uplink trial with 3 transmit antennas
Samsung Electronics and MediaTek have successfully conducted 5G standalone (SA) uplink tests, using three transmit (3Tx) antennas instead of the typical two, to demonstrate the potential for improved upload experiences with current smartphones and customer premise equipment (CPE).
Until recently, most talk about 5G SA industry firsts have focused on the downlink. However, the demands on uplink performance are increasing with the rise of live streaming, multi-player gaming and video conferences. Upload speeds determine how fast your device can send data to gaming servers or transmit high-resolution videos to the cloud. As more consumers seek to document and share their experiences with the world in real-time, enhanced uplink experiences provide an opportunity to use the network to improve how they map out their route home, check player stats online and upload videos and selfies to share with friends and followers.
While current smartphones and customer premise equipment (CPEs) can only support 2Tx antennas, this industry-first demonstration validated the enhanced mobile capability of 3Tx antenna support. This approach not only improves upload speeds but also enhances spectrum and data transmission efficiency, as well as overall network performance.
The test was conducted in Samsung’s lab, based in Suwon, Korea. Samsung provided its industry-leading 5G network solutions, including its C-Band Massive MIMO radios, virtualized Distributed Unit (vDU) and core. The MediaTek test device featuring its new M80-based CPE chipset began with one uplink channel apiece at 1,900MHz and 3.7GHz, but added an extra uplink flow using MIMO on 3.7GHz. Both companies achieved a peak throughput rate of 363Mbps, an uplink speed that is near theoretical peak using 3Tx antennas.

“We are excited to have successfully achieved this industry breakthrough with MediaTek, bringing greater efficiency and performance to consumer devices,” said Dongwoo Lee, Head of Technology Solution Group, Networks Business at Samsung Electronics. “Faster uplink speeds bring new possibilities and have the potential to transform user experiences. This milestone further demonstrates our commitment to improving our customers’ networks using the most advanced technology available.”
“Enhancing uplink performance using groundbreaking tri-antenna and 5G UL infrastructure technologies will ensure next-generation 5G experiences continue to impress users globally,” said HC Hwang, General Manager of Wireless Communication System and Partnership at MediaTek. “Our collaboration with Samsung has proved our combined technical capabilities to overcome previous limits, enhancing network performance and efficiency, opening up new possibilities for service providers and consumers to enjoy faster and more reliable 5G data connectivity.”
“With demands on mobile networks rising, enhancing upload performance is essential to improving consumer and enterprise connectivity, as well as application experiences,” said Will Townsend, VP & Principal Analyst at Moor Insights & Strategy. “Samsung and MediaTek have achieved an important 5G Standalone milestone in a demonstration which underscores a tangible network benefit and does so in a way that can help operators maximize efficiency.”
Samsung has pioneered the successful delivery of 5G end-to-end solutions, including chipsets, radios and core. Through ongoing research and development, Samsung drives the industry to advance 5G networks with its market-leading product portfolio, from virtualized RAN and Core to private network solutions and AI-powered automation tools. The company currently provides network solutions to mobile operators that deliver connectivity to hundreds of millions of users worldwide.

Through the combination of these networks, KKR will establish ON*NET Fibra de Perú as the new name for the platform which will independently build and operate the nation’s largest fiber optic network with world-class quality standards. KKR will own a 54% interest in ON*NET Fibra de Perú alongside Telefónica Hispanoamérica, which will own 36%, and Entel Perú, which will own 10%.
The entire ON*NET Fibra de Perú fiber optic network will be open to use by all internet service providers, increasing competition in the wholesale market. Telefónica del Perú and Entel Perú will be anchor tenants on the expanded open access network, enabling both providers to reach a greater number of customers with ultra-high-speed offerings. The transaction does not impact the services provided by existing customers of PangeaCo, Telefónica del Perú or Entel Perú. Upon closing of the transaction, customers will benefit from the scale of the larger network.
In Perú, approximately 88% of households have mobile or fixed internet service, but less than 35% have access to high-speed fiber optic networks.1 KKR, as the controlling shareholder, intends for ON*NET Fibra de Perú to more than double the households reached by fiber optic network, including reaching municipal areas outside of Lima as well as middle- and low-income households. This transaction demonstrates continued investor confidence in Peruvian infrastructure and the commitment of the companies to contribute to the sustainable development of the digital connectivity in the country.
Today’s announcement builds on KKR’s success in expanding nationwide connectivity and increasing competition in Chile and Colombia. ON*NET Fibra de Chile has expanded access from 2.4 million homes passed to 3.7 million homes passed since KKR signed the acquisition in February 2021 and ON*NET Fibra de Colombia has increased homes passed from 1.2 million to 2.4 million since signing in July 2021.2 Both companies have attracted multiple internet service providers to utilize their open access networks.
KKR is making the investment through its KKR Global Infrastructure Investors III fund and plans to provide operational support to ON*NET Fibra de Perú through NEXO LatAm, a digital infrastructure business supporting KKR’s Infrastructure strategy across Latin America. KKR and NEXO LatAm have significant experience supporting the successful expansion of open access fiber optic investments. The transaction is subject to regulatory approvals, including the approval of the Peruvian antitrust agency (INDECOPI).

From telecoms.com:
When Telefonica first sold a stake in its Chilean fibre business to KKR it had a footprint of 2.4 million homes passed. The deal valued the entire business at $1 billion. The Colombian fiber business that KKR bought into was valued at half that amount and just over half the footprint:1.2 million homes. Admittedly, the Colombia deal was inked two years ago and Chile even longer ago, and a fair bit has changed in the economic situation in that time. However, we can get a sense of the scale of spend we might be looking at.
KKR wants to share the progress made by those Chilean and Colombian ventures. ON*NET Fibra de Chile passed 3.7 million homes as of the end of 2022, while ON*NET Fibra de Colombia had doubled the number of homes passed to 2.4 million, it said, adding that both have attracted multiple ISP customers.
That surely bodes well for the new venture’s aims in Peru, where at present around 88% of households have mobile or fixed internet service, but less than 35% have access to high-speed fibre networks, KKR said, citing data from regulator OSIPTEL and market research firm Omdia (owned by Informa).
It should also help smooth the regulatory process. The deal needs a number of approvals, including that of Peruvian antitrust agency INDECOPI, but it’s hard to foresee any major difficulties, given that this is an established model across the region and one that seems to be working.
