India’s TRAI releases Recommendations on use of Tera Hertz Spectrum for 6G
Telecom Regulatory Authority of India (TRAI) is urging the government and wireless network operators to explore the use of terahertz spectrum for new 6G technologies and services. “The government should introduce a new experimental authorization for the spectrum in the 95 GHz to 3 THz range termed as ‘Tera Hertz Experimental Authorization’ [THEA],” said a press release issued by TRAI.
THEA’s primary objective would be to promote “research and development (R&D), indoor and outdoor testing, technology trial, experimentation and demonstration in the 95 GHz to 3 TZ range,” said TRAI. Any Indian entity, including academic institutes, R&D labs, telecom service providers, central or state government bodies and original equipment makers, will be eligible for an authorization covering a maximum of five years. The scope of THEA should be to conduct R&D, indoor and outdoor testing, technology trial, experimentation, and demonstration in the 95 GHz to 3 THz range; and to market experimental devices designed to operate in the 95 GHz to 3 THz range via direct sale.
TRAI believes the terahertz frequency band is likely to play a crucial role in upcoming 6G technology. “The high-speed point-to-point wireless data link is an emerging usage of Terahertz radiation,” said TRAI in its recommendations. “For this reason, communications in the Terahertz band are expected to play a pivotal role in the upcoming 6th generation (6G) of wireless mobile communications, enabling ultra-high bandwidth communication paradigms.”
“The large Terahertz bandwidths and massive antenna arrays, combined with the inherent densification caused by machine-type communications, will result in an enhanced communication system performance,” added TRAI.
“TRAI is laying the groundwork for India to become a global powerhouse in testing as well as in research and development so that we are fully geared to produce cutting-edge technologies and services in the near future,” said TV Ramachandran, the president of the Broadband India Forum (BIF), in his response to the announcement.
The recommendations are a further sign of India’s interest in shaping the 6G standard, likely to appear around 2030. Vocal about its ambitions, India has already set up the Bharat 6G Alliance to actively contribute to 6G activities. It has also collaborated with several organizations, including the US-based Next G Alliance, Europe’s 6G Smart Networks and Services Industry Association (6G IA) and the 6G Flagship of Oulu University as it tries to position itself as a “global leader” in digital infrastructure and innovation.
The terahertz band has been attracting attention as an option for 6G deployment, with the European Telecommunications Standards Institute (ETSI) recently releasing two reports on the band and the use cases it could support.
“Due to their shorter wavelengths, Terahertz communication systems can support higher link directionality, are less susceptible to free-space diffraction and inter-antenna interference, can be realized in much smaller footprints, and possess a higher resilience to eavesdropping,” said the TRAI report. Even so, there are several challenges that would need to be addressed before terahertz could be feasible for widespread usage. Above all, signal propagation is generally weak in higher frequency bands and power limitations can also result in poor coverage, said TRAI.
The Recommendations have been placed on the TRAI’s website (www.trai.gov.in). For any clarification! information Shri Akhilesh Kumar Trivedi, Advisor (Networks, Spectrum and Licensing), TRAI may be contacted at Telephone Number +91-11-20907758.

KT and LG Electronics to cooperate on 6G technologies and standards, especially full-duplex communications
In a joint statement, KT (South Korea’s #2 mobile network operator) and LG Electronics will work together to promote 6G technology research and technology standardization. The two companies plan to develop full-duplex communication technology, global standardization cooperation (presumably in 3GPP and ITU-R WP5D for IMT-2030), and 6G application services and next-generation transmission technologies. The companies had previously announced partnerships to develop AI service platforms and AI service robots.
Full-duplex communications will be introduced as part of the 5G-Advanced Release 18 and is expected to increase spectrum efficiency by enabling uplink and downlink data to be simultaneously transmitted and received over a single frequency band. The companies said it can increase frequency efficiency by up to two times. They will design technologies that operate in the 6G candidate frequency bands and transmit and receive simultaneously to verify actual performance. The duo also plan to promote global standardization of 6G (that can only be done by ITU-R IMT-2030 recommendations).
“Through this 6G research and development collaboration with LG Electronics, KT expects to lead the development of 6G mobile communication technology and strengthen its global standardization leadership,” said Lee Jong-sik, executive director of KT Network Research Institute. “We will do our best to secure innovative network technology and capabilities for providing differentiated services.”
Je Young-ho, executive director of LG Electronics C&M Standard Research Institute added: “LG Electronics has been proactively leading research and development to discover core 6G technologies since 2019,” and added, “Through our collaboration with KT, we expect to contribute greatly to not only leading 6G standardization, but also discovering core services.”

Chinese engineers field test a “6G” network with semantic communications on 4G infrastructure
According to the Xinhua news agency, Chinese telecom engineers have established the world’s first field test network for 6G communication and intelligent integration. That’s before 6G is even defined let alone specified by ITU-R WP5D or 3GPP Release 21. The experimental network has demonstrated that semantic communication [1.] can reach the transmission capabilities of 6G on existing 4G infrastructure.
Note 1. Semantic communication aims at the successful transmission of information conveyed by the source rather than the accurate reception of each single symbol or bit regardless of its meaning.
The network has achieved a remarkable tenfold improvement in key communication metrics, including capacity, coverage and efficiency, according to a team from Beijing University of Posts and Telecommunications who unveiled their work at a seminar on July 10th. The network serves as a platform which facilitates the efforts of research institutions in conducting theoretical research and initial verification of 6G pivotal technologies. It can effectively lower the entry threshold for 6G research, making it more accessible for innovation, according to the team.
“The integration of the two will accelerate the formation of new business forms of the digital economy,” Professor Zhang Ping, who heads the university’s research team, reportedly said at the conference where the 6G field test network was unveiled. “AI will improve the perception and semantic understanding of communication, while the ubiquitous communication of 6G will in turn extend the reach of artificial intelligence to all corners of all fields,” Zhang was quoted as saying.

China is working to commercialize 6G, the next-generation wireless technology after 5G, by around 2030, the same time at which 6G standards are expected to be completed. The ITU-R says 6G could promote the growth of a range of advances, allowing communication to be immersive and connectivity universal. But with existing communication technology reaching its theoretical bandwidth limit, there are a series of big problems that have to be overcome. These include the difficulty of increasing capacity, the high cost of coverage, and high energy consumption.
The 6G technology market is also expected to enable major improvements in imaging, presence technology and location awareness. In conjunction with AI, the 6G computing infrastructure should be able to determine the best location for computing, including decisions about data storage, processing and sharing.

ITU-R: IMT-2030 (6G) Backgrounder and Envisioned Capabilities
ITU-R vs 3GPP – 5G and 6G Standards and Specifications:
For new IEEE Techblog readers, ITU-R is responsible for radio interfaces with WP 5D making the ITU-R recommendations (standards) for IMT Radio Interface Technologies (RITs) and Set of Radio Interface Technologies (SRITs).
For 5G, it was called IMT 2020 (M.2150 recommendation) and for 6G, it’s called IMT-2030. 3GPP contributions towards those standards have been presented to WP5D by ATIS – one of the organizational partners of 3GPP.
While ITU-T was supposed to standardize non-radio aspects of 5G, 5G Advanced and 6G, that did not happen. Instead, those specifications, including the 5G and 6G core networks, are being developed by 3GPP. Those 3GPP 5G and 6G non-radio specs have to be transposed and adopted by official standards bodies, such as ETSI.
Please see References and Comments below for more information.
…………………………………………………………………………………………………….
Backgrounder:
In February 2021, the ITU started the development of ITU-R Framework Recommendation for IMT-2030 (6G) which was approved by the Radio Assembly 2023 and published as Recommendation ITU‑R M.2160 – Framework and overall objectives of the future development of IMT for 2030 and beyond. Based on this Recommendation, the ITU has started the process of the development of IMT-2030. The IMT-2030 terrestrial radio interface specification is expected to be completed in 2030. M.2160 describes these motivation and societal considerations, potential user and application trends, technology trends, spectrum harmonization and envisaged frequency bands. Also ITU-R Report M.2156 “Future technology trends of terrestrial IMT systems towards 2030 and beyond” and Report ITU-R M.2541 “Technical feasibility of IMT in bands above 100 GHz” details these expected trends and phenomena for IMT-2030.
The framework and objectives including overall timeframes for the future development of IMT for 2030 and beyond are described in some detail in Recommendation ITU-R M.2160.
In order to fulfil these varied demands, Usage scenarios of IMT-2030 are envisioned to expand on those of IMT-2020 (i.e., eMBB, URLLC, and mMTC introduced in Recommendation ITU-R M.2083) into broader use requiring evolved and new capabilities. In addition to expanded IMT‑2020 usage scenarios, IMT-2030 is envisaged to enable new usage scenarios arising from capabilities, such as artificial intelligence and sensing, which previous generations of IMT were not designed to support. Figure 1. below illustrates the usage scenarios for IMT-2030.
Figure 1. Usage scenarios and overarching aspects of IMT-2030:
Capabilities of IMT-2030:
IMT-2030 is expected to provide enhanced capabilities compared to those described for IMT-2020 in Recommendation ITU-R M.2083, as well as new capabilities to support the expanded usage scenarios of IMT-2030. In addition, each capability could have different relevance and applicability in the different usage scenarios.
The range of values given for capabilities are estimated targets for research and investigation of IMT-2030. All values in the range have equal priority in research and investigation. For each usage scenario, a single or multiple values within the range would be developed in future in other ITU-R Recommendations/Reports. These values may further depend on certain parameters and assumptions including, but not limited to, frequency range, bandwidth, and deployment scenario. Further these values for the capabilities apply only to some of the usage scenarios and may not be reached simultaneously in a specific usage scenario.
The capabilities of IMT-2030 include:
1) Peak data rate
Maximum achievable data rate under ideal conditions per device. The research target of peak data rate would be greater than that of IMT-2020. Values of 50, 100, 200 Gbit/s are given as possible examples applicable for specific scenarios, while other values may also be considered.
2) User experienced data rate
Achievable data rate that is available ubiquitously[1] across the coverage area to a mobile device. The research target of user experienced data rate would be greater than that of IMT-2020. Values of 300 Mbit/s and 500 Mbit/s are given as possible examples, while other values greater than these examples may also be explored and considered accordingly.
3) Spectrum efficiency
Spectrum efficiency refers to average data throughput per unit of spectrum resource and per cell[2]. The research target of spectrum efficiency would be greater than that of IMT-2020. Values of 1.5 and 3 times greater than that of IMT-2020 could be a possible example, while other values greater than these examples may also be explored and considered accordingly.
4) Area traffic capacity
Total traffic throughput served per geographic area. The research target of area traffic capacity would be greater than that of IMT-2020. Values of 30 Mbit/s/m2 and 50 Mbit/s/m2 are given as possible examples, while other values greater than these examples may also be explored and considered accordingly.
5) Connection Density
Total number of connected and/or accessible devices per unit area. The research target of connection density could be 106 – 108 devices/km2.
6) Mobility
Maximum speed, at which a defined QoS and seamless transfer between radio nodes which may belong to different layers and/or radio access technologies (multi-layer/multi-RAT) can be achieved. The research target of mobility could be 500 – 1 000 km/h.
7) Latency
Latency over the air interface refers to the contribution by the radio network to the time from when the source sends a packet of a certain size to when the destination receives it. The research target of latency (over the air interface) could be 0.1 – 1 ms.
8) Reliability
Reliability over the air interface relates to the capability of transmitting successfully a predefined amount of data within a predetermined time duration with a given probability.
The research target of reliability (over the air interface) could range from 1-10−5 to 1-10−7.
9) Coverage
Coverage refers to the ability to provide access to communication services for users in a desired service area. In the context of this capability, coverage is defined as the cell edge distance of a single cell through link budget analysis.
10) Positioning
Positioning is the ability to calculate the approximate position of connected devices. Positioning accuracy is defined as the difference between the calculated horizontal/vertical position and the actual horizontal/vertical position of a device.
The research target of the positioning accuracy could be 1 – 10 cm.
11) Sensing-related capabilities
Sensing-related capabilities refer to the ability to provide functionalities in the radio interface including range/velocity/angle estimation, object detection, localization, imaging, mapping, etc. These capabilities could be measured in terms of accuracy, resolution, detection rate, false alarm rate, etc.
12) Applicable AI-related capabilities
Applicable AI-related capabilities refer to the ability to provide certain functionalities throughout IMT-2030 to support AI enabled applications. These functionalities include, distributed data processing, distributed learning, AI computing, AI model execution, and AI model inference, etc.
13) Security and resilience
In the context of IMT-2030:
− Security refers to preservation of confidentiality, integrity, and availability of information, such as user data and signalling, and protection of networks, devices and systems against cyberattacks such as hacking, distributed denial of service, man in the middle attacks, etc.
− Resilience refers to capabilities of the networks and systems to continue operating correctly during and after a natural or man-made disturbance, such as the loss of primary source of power, etc.
14) Sustainability
Sustainability, or more specifically environmental sustainability, refers to the ability of both the network and devices to minimize greenhouse gas emissions and other environmental impacts throughout their life cycle. Important factors include improving energy efficiency, minimizing energy consumption and the use of resources, for example by optimizing for equipment longevity, repair, reuse and recycling.
Energy efficiency is a quantifiable metric of sustainability. It refers to the quantity of information bits transmitted or received, per unit of energy consumption (in bit/Joule). Energy efficiency is expected to be improved appropriately with the capacity increase in order to minimize overall power consumption.
15) Interoperability
Interoperability refers to the radio interface being based on member-inclusivity and transparency, so as to enable functionality(ies) between different entities of the system. The capabilities of IMT-2030 are shown in Figure 2. below.
FIGURE 2. Capabilities of IMT-2030:
NOTES:
[1] The term “ubiquitous” is related to the considered target coverage area and is not intended to relate to an entire region or country.
[2] The coverage area over which a mobile terminal can maintain a connection with one or more units of radio equipment located within that area. For an individual base station, this is the coverage area of the base station or of a subsystem (e.g., sector antenna).
Relationship between existing IMT and IMT-2030:
In order to support emerging usage scenarios and applications for 2030 and beyond, it is foreseen that development of IMT-2030 would be required to offer enhanced capabilities as described in § 3. The values of these capabilities go beyond those described in Recommendation ITU-R M.2083. The minimum technical requirements (and corresponding evaluation criteria) are to be defined by ITU‑R based on these capabilities for IMT-2030. They could potentially be met by adding enhancements to existing IMT, incorporating new technology components and functionalities, and/or the development of new radio interface technologies. Furthermore, IMT-2030 is envisaged to interwork with existing IMT.

Separately, ATIS’ Next G Alliance (NGA) recently announced publication of Spectrum Needs for 6G, which assesses 6G spectrum needs based on scenario-specific key performance indicators and application-specific technical performance requirements.
The methodology used for estimating spectrum needs is based on the data rate requirements of 6G applications, with an emphasis on North American context and needs. The applications considered reflect the NGA’s collective efforts in establishing a comprehensive 6G roadmap.
“Proactively understanding next G spectrum needs and planning for them is essential to U.S. leadership in critical and emerging technologies,” said Next G Alliance Managing Director, David Young. “Decisions about the use of spectrum depend on multiple aspects and require time to be implemented. This paper achieves an understanding of 6G spectrum needs so that these needs are considered in the development of data-driven policies, regulatory decisions, and technical solutions.”

GSMA: China’s 5G market set to top 1 billion this year
China’s state sponsored 5G market is expected to add almost US$260 billion to its gross domestic product in 2030, with its 5G connections accounting for nearly a third of the worldwide total according to a recent GSMA report.
The report forecasts that more than half of Chinese mobile connections will be 5G by the end of 2024. 5G’s contribution to GDP in China is expected to reach almost $260 billion in 2030, which is 23% of the overall annual economic impact of mobile in China. Also by 2030, 5G connections in China will account for nearly a third of the global total, with 5G adoption in China reaching almost 90%, making it one of the leading markets globally.
The mobile industry contributed to 5.5% of China’s GDP last year, and in each of the coming years through 2030, nearly a quarter of that contribution will come from 5G – the highest echelon of current cellular technology – per the results of a study issued on Tuesday by the Group System for Mobile communications Association (GSMA).
Overall, the mobile market’s contribution to the Chinese economy will reach around US$1.1 trillion in 2030, GSMA said. Mats Granryd, Director General of the GSMA, said:
“It is great to see China, the world’s largest 5G market, commit so enthusiastically to the GSMA’s Open Gateway initiative to help drive the growth and maturity of the technology. As China surpasses 1 billion 5G connections this year, we expect to see further investment and potential in evolutions such as 5G-Advanced, 5G New Calling and 5G RedCap to improve user experience and unlock new revenue streams for operators.”

GSMA’s Mobile Economy China 2024 report said the country’s entire mobile sector has so far provided a total of nearly 8 million jobs directly and indirectly, and generated US$110 billion in tax revenue in 2023 alone. According to that report:
- There are now 1.28 billion unique mobile subscribers in China – a penetration rate of 88%
- Mobile’s overall contribution to the Chinese economy in 2023 reached $970 billion, or 5.5% of GDP
- 5G is expected to reach 1.6bn connections in 2030, representing a third of the world’s total, and forecast to contribute $260 billion to China’s GDP
- An additional 290 million people in China now use mobile internet compared to eight years ago (2015), closing the country’s Usage Gap from 43% to just 16%
- Mobile data traffic in China is expected to quadruple by the end of the decade
China has the world’s most mobile phone users by a wide margin. As of the end of last year, there were 122.5 mobile phones for every 100 people, according to figures from the National Bureau of Statistics. The number of 5G base stations was nearly 3.38 million – a surge of 46% from a year earlier.
“China continues to set the pace for cutting-edge 5G technology standards,”the GSMA said, adding the country’s operators are “leading the way in the transition to 5G-advanced and 5G reduced capability networks. This is anticipated to kick-start a new round of 5G investment in 2024 and beyond.”

Ericsson and IIT Kharagpur partner for joint research in AI and 6G
Ericsson and the Indian Institute of Technology (IIT) Kharagpur have announced a partnership for a long-term cooperation for joint research in the area of radio, computing and AI (artificial intelligence). Both organisations have signed two milestone agreements. As part of the agreements, researchers from IIT Kharagpur and Ericsson will collaborate to develop novel AI and distributed compute tech for 6G. Leaders from IIT Kharagpur and Ericsson participated in discussing the developments and advancements for the future of networks and communications at the GS Sanyal School Telecommunications (GSSST).

……………………………………………………………………………………………………….
Two key initiatives finalized by Ericsson and IIT were:
a) Compute offload and Resource Optimisation at edge compute: The project aims to explore resource optimization, dynamic observability and sustainable distributed and Edge computing technologies.
b) RL-based Beamforming for JCAS: Safe, Causal, and Verifiable: The project aims to explore causal AI methods for joint communication and sensing (JCAS).
…………………………………………………………………………………………………………….
AI and Compute Research is instrumental to Ericsson’s 6G networks as the compute offload needs to be managed dynamically at edge and the policies would primarily be driven by AI. These themes of research are well aligned with IIT Kharagpur and both organizations view this partnership as a way to push the boundaries of fundamental and applied research in the Radio domain.
Editor’s Note:
Ericsson laid off 8,500 employees last year as part of its cost-cutting initiatives and reduced total costs by 12 billion Swedish crowns ($1.15 billion) in 2023.
Telecoms equipment suppliers are expecting a challenging 2024 as 5G equipment sales – a key source of revenue – are slowing in North America, while India, a growth market, may also see a slowdown. Ericsson’s fourth-quarter net sales fell 16% to 71.9 billion Swedish crowns ($6.89 billion), missing estimates of 76.64 billion.
……………………………………………………………………………………………………………..
Magnus Frodigh, Head of Ericsson Research, says: “This collaboration strengthens our R&D commitments in India and is pivotal to Radio, Compute and AI research. We are excited to partner with IIT Kharagpur and look forward to collaborative research in fundamental areas as well as translational research for our Future Network Platforms”. Dr Frodigh also presented Ericsson’s vision on 6G which aims to blend the physical and digital worlds enabling us to improve the quality of life by incorporating widespread Sensor-based communications between humans and machines through digital twins.
Nitin Bansal, Managing Director of Ericsson India said, “Ericsson is well poised to lead 6G innovation and we are making significant R&D investments in India in line with our commitment to the country. Given our 5G and technology leadership, our research initiatives are geared to provide affordable network platforms for ubiquitous connectivity all across the country.”
Virendra Kumar, Director at IIT Kharagpur, said, “In the commitment towards Digital India and making India the hub of technological innovation, this collaboration with Ericsson will be effective for next-generation technology significantly. 6G networks integrated with artificial intelligence will enable AI-powered applications to run faster and more efficiently. In the 6G era, IIT Kharagpur aims to contribute to Radio Access Technology and Network, Core Network, RF & Device Technologies, VLSI Design, Neuromorphic Signal Processing, Services and Applications.”

ETSI Integrated Sensing and Communications ISG targets 6G
The new ETSI Industry Specification Group for Integrated Sensing and Communications (ISG ISAC). This group will establish the technical foundations for ISAC technology development and standardization of 6G.
87 participants from both the industrial sphere and the academic sphere took an active part in the kick-off meeting, which was held at ETSI premises in Sophia Antipolis, France, on 17 November 2023.
“Integrated Sensing and Communications add a new element of capability to the wireless network, enabling new innovative use cases in transport, urban environments, homes, and factories, ranging from object and intruder detection in predefined secure areas around critical infrastructures to fall detection and rain/pollution monitoring” explains Dr. Alain Mourad, Chair of the ISAC ISG.
The ETSI ISAC ISG’s mission is to enable ETSI members to coordinate their 6G pre-standard research efforts on ISAC, particularly across various European/National-funded collaborative projects, extended through relevant global initiatives, paving the way for the 6G standardization of the technology.
The ISG will target systematic outputs on ISAC into international standards organizations, namely future 3GPP 6G releases (e.g., R20+) and ITU-R IMT-2030 deliverables, related to ISAC requirements and evaluation methodologies.
Within this context, sensing refers to the use of radio signals to detect and estimate characteristics of target objects in the environment. By integrating sensing into the communications network, the network acts as a “radar” sensor, using its own radio signals to sense and comprehend the physical world in which it operates. This allows the network to collect data on the range, velocity, position, orientation, size, shape, image, materials of objects and devices.
The sensing data collected and processed by the network can then be leveraged to enhance the network’s own operations, augment existing services such as XR and digital twinning, and enable new services, such as gesture and activity recognition, object detection and tracking, along with imaging and environment reconstruction.
The ETSI ISAC ISG will define a prioritized set of 6G use cases and sensing types, along with a roadmap for their analysis and evaluation. It will focus on advanced 6G use cases and sensing types which are not expected to be covered by 3GPP Release 19. These advancements may potentially be included in future 6G releases of 3GPP. The group also aims to develop advanced channel models for ISAC use cases and sensing types, with validation through extensive measurement campaigns, addressing gaps in existing communications-based channel models (e.g., 3GPP, IEEE 802. ITU-R).
Output for architectures and deployment considerations, KPIs, and evaluation assumptions will also be provided. In parallel, the group will undertake two studies, with a first analysis of the privacy and security aspects associated with sensing data within the ISAC 6G framework, and a second analysis of the impact of widespread deployment of ISAC on the UN sustainable development goals.

The idea of using a network to sense objects was also offered up by Nokia at MWC this year as a potential 6G use case. Head of Europe Rolf Werner told Telecoms.com:
“Temperature, wavelength, infrared, you can do stuff which goes all around. You can tune an airport [so you] don’t have to show a passport… you walk through because the network is able to gain information from everything you have… there’s a lot of stuff coming around. 6G in 2030 is our visionary year, or that’s when we think it will kick in. Of course a lot of things have to happen before that.”
ETSI’s ISG ISAC group will be producing a study around the privacy and security aspects around sensing which seems prudent, since there are bound to be some concerns raised about the potential implications of a network sensing all sorts of data points on people and objects if that becomes a key facet of the future 6G marketing machine.

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:

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.

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.
