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.”

……………………………………………………………………………………………………….
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.

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. To get involved with this new activity, please contact [email protected]
………………………………………………………………………………………………………………………
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:
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.

China’s MIIT to prioritize 6G project, accelerate 5G and gigabit optical network deployments in 2023
Big 5G Conference: 6G spectrum sharing should learn from CBRS experiences
Spectrum sharing is a methodology that allows multiple wireless networks to access the same frequency band dynamically and efficiently. It can reduce the spectrum scarcity issue and enable more wireless applications and services, but also requires careful coordination and management to avoid interference and ensure fair access.
Examples of spectrum sharing techniques include Licensed Shared Access (LSA), which uses a regulatory framework to permit licensed users to share spectrum with incumbent users, Dynamic Spectrum Access (DSA), which enables wireless networks to sense and adapt to the spectrum environment, and Spectrum Aggregation, which combines multiple spectrum bands or channels into a larger bandwidth. LSA can be used by mobile operators to access spectrum that is not used by TV broadcasters, DSA can be employed by cognitive radio networks to detect and avoid channels occupied by primary users, Spectrum Aggregation can be used by 5G networks for coverage and speed.
The wireless telecom industry has to take a “concerted look at revolutionizing spectrum sharing” and to take a closer look at the lessons learned from CBRS spectrum sharing [1.], which took about a decade to be successfully implemented, according to Andrew Thiessen, chair of the spectrum working group at the Next G Alliance who was speaking at the Informa Big 5G conference panel session in Austin, TX. He opined that the industry needs to be pushing ahead with spectrum sharing technologies and techniques at speeds similar to the innovations that are being applied to smartphones.
Note 1. Citizens Broadband Radio Service (CBRS), which allows for dynamic spectrum sharing between the Department of Defense and commercial spectrum users. The DOD users have protected, prioritized use of the spectrum. When the government isn’t using the airwaves, companies and the public can gain access through a tiered licensing arrangement. This means the DOD can use the same spectrum for its critical missions while companies can use it for 5G and high-speed Internet deployment.
“Innovative spectrum sharing frameworks are key to unlocking additional bandwidth for wireless connectivity across the country,” Deputy Assistant Secretary of Commerce for Communications and Information April McClain-Delaney said. “The success and growth of the CBRS band shows the promise of dynamic spectrum sharing to make more efficient use of this finite resource.”
………………………………………………………………………………………………………………………………………………..
Joe Kochan, executive director of the National Spectrum Consortium, agreed that spectrum sharing for 6G does present challenges as it faces a wide range of commercial users, federal users and non-federal users, as well as different types of technologies, such as radar. That elicits a need for the industry to build new tools and to get more creative about how that spectrum can be shared.
The Biden administration’s National Spectrum Strategy will “lay the framework” to get everything moving, said Derek Khlopin, deputy associate administrator, spectrum planning policy, at the NTIA. “We’re tech and application-neutral. But the better we understand, the better we can plan.” he explained.
“We’ve started listening, to be frank,” Khlopin said. “But it’s not necessarily the role of the government to figure all of this out. We need help, so we’re working closely with industry, with academia and others. Spectrum sharing is here to stay between federal and non-federal users,” he added.
Khlopin was asked about NTIA’s exploration of the 7GHz band and its potential for 6G. “It’s a very complicated band,” he said. “There’s a lot there … We’re aware of the industry interest there.”
Thiessen said one challenge for 6G will be a lack of contiguous spectrum. He believes that 6G will likely be made up of a lot of pieces of spectrum, and those pieces will likely need to be targeted to specific use cases. However, that presumption is premature as neither 3GPP or ITU-R WP5D has started any serious work on defining 6G specifications. That is why all the buzz about 6G is irrelevant at this time.

Vodafone tests 5G Dynamic Spectrum Sharing (DSS) in its Dusseldorf lab
Keysight and partners make UK’s first 100 Gbps “6G” Sub-THz connection
Highlights:
- Data link made at speeds greater than 100 Gbps at a frequency of 300 GHz using both 32 and 64 quadrature amplitude modulation
- Achievement enabled by Keysight’s 6G sub-THz testbed platform
Keysight Technologies, Inc, in collaboration with National Physical Laboratory (NPL) and the University of Surrey, has made the first 6G connection at speeds greater than 100 gigabits per second (Gbps) over sub-terahertz (THz) frequencies in the U.K.
Future 6G use cases, such as augmented reality and autonomous vehicles, will require data throughput speeds from 100 Gbps to 1 terabit per second (Tbps). To achieve the extreme data speeds and low latencies required by these revolutionary use cases, the use of sub-THz frequencies is being explored. However, operations in sub-THz frequency bands introduce signal integrity and path loss challenges that can negatively impact performance.
Keysight, NPL, and the University of Surrey established the first sub-THz high throughput 6G testbed in the U.K. to address these challenges. Funded by the U.K. government for 6G research, NPL and Surrey scientists are using the testbed to study and characterize sub-THz signal performance to generate new techniques for optimizing data paths and calibration methodologies.
Located at NPL, this new 6G testbed achieved the U.K.’s first high-speed sub-THz data link. The demonstration was made at a frequency of 300 GHz using both 32 and 64 quadrature amplitude modulation (QAM). Built on Keysight’s 6G Sub-Terahertz R&D Testbed, the testbed uses the M8194A Arbitrary Waveform Generator (AWG) combined with Virginia Diodes Inc. (VDI) upconverters / downconverters to generate the signal and Keysight’s UXR0704A Infiniium multichannel high-performance 70 GHz oscilloscope to analyze the signal.
Keysight, NPL, and the University of Surrey will demonstrate the new 6G testbed at the Spring 2023 6G Symposium at the University of Surrey, April 24-26.

India unveils Bharat 6G vision document, launches 6G research and development testbed
Despite being very late in rolling out 5G [1.], without TSDSI’s 5Gi ITU-R standard, India is ONCE AGAIN talking up 6G. Prime Minister Narendra Modi opened the new United Nations’ ITU area office and Innovation Centre on Wednesday and revealed the Bharat 6G Vision document and launched the 6G R&D Test Bed.
Note 1. Indian telecom service providers started to deploy 5G services in October 2022.
The Indian government’s Bharat 6G vision document was prepared by the Technology Innovation Group on 6G (TIG-6G), which was formed in November 2021 to build a roadmap and action plans for 6G in India, according to an official statement. Officials from Ministries/Departments, experts from research and development institutions, academia, standardisation bodies, telecom service providers, and business are among the members.
The 6G Test Bed will provide a platform for academic institutions, industry, start-ups, MSMEs, and industry, among others, to test and verify evolving ICT technologies.
The Bharat 6G Vision Document and 6G Test Bed, according to Centre, will create an enabling environment for innovation, capacity building, and faster technology adoption in India.

“Today India is the fastest 5G rollout country in the world. In just 120 days, 5G has been rolled out in more than 125 cities. Today 5G services have reached about 350 districts of the country. Moreover, today we are talking about 6G only after six months of 5G rollout and this shows India’s confidence,” Modi said, according to a transcript of his address at the inauguration of a new ITU Area Office & Innovation Center in New Delhi. “Today we have also presented our vision document. This will become a major basis for 6G rollout in the next few years,” Modi added.
The Bharat 6G vision document foresees 6G services launched in India by the second or third quarter of 2024. That would enable India to move ahead from 5G services in just 2 short years. According to government sources, India’s 6G mission will be completed in two phases- 1] from 2023 to 2025 and 2] from 2026 to 2030.

IMT Vision – Framework and overall objectives of the future development of IMT for 2030 and beyond
This ITU-R recommendation in progress will be the main focus of next week’s ITU-R WP5D meeting #43 in Geneva. It defines the framework and overall objectives for the development of International Mobile Telecommunications (IMT) for 2030 and beyond. There are contributions related to this recommendation from: Apple, Nokia, Ericsson, Wireless World Research Forum, Motorola Mobility, Orange, United Kingdom of Great Britain and Northern Ireland, Finland, Germany, GSOA, China, Qualcomm, Electronics and Telecommunications Research Institute (ETRI), Brazil, Samsung, ZTE, Huawei, InterDigital, Intel and India, with several being multi-company contributions.
The objective is to reach a consensus on the global vision for IMT-2030 (aka 6G), including identifying the potential user application trends and emerging technology trends, defining enhanced and brand-new usage scenarios and corresponding capabilities, as well as understanding the new spectrum needs.
IMT will continue to better serve the needs of the networked society, for both developed and developing countries in the future and this Recommendation outlines how that will be accomplished. This Recommendation also intends to drive the industries and administrations for encouraging further development of IMT for 2030 and beyond.
The framework of the development of IMT for 2030 and beyond, including a broad variety of capabilities associated with envisaged usage scenarios, is described in detail in this Recommendation.
In June 2022, ITU-R decided on the overall timeline for 6G with three major stages:
- Stage 1 – vision definition to be completed in June 2023 before the World Radiocommunication Conference 2023 (WRC-23),
- Stage 2 – requirements and evaluation methodology to be completed in 2026, and
- Stage 3 – specifications to be completed in 2030. The 3-stage timeline and the tasks for each stage are summarized in Figure below.

This draft Recommendation defines a [potential] framework and overall objectives for the development of the terrestrial component of International Mobile Telecommunications (IMT) for 2030 and beyond. IMT will continue to better serve the needs of the [networked] society, for both developed and developing countries in the future and this [Recommendation/document] outlines how [possibly] that could be accomplished. This [Recommendation/document] also intends to encourage further development of IMT-2030. In this [Recommendation/document], the [potential] framework of the development of IMT-2030, including a broad variety of capabilities associated with [some possible] envisaged usage scenarios[, and those yet to be developed and] described in detail. Furthermore, this [Recommendation/document] addresses the objectives for the development of IMT-2030, which includes further enhancement and evolution of existing IMT and the development of IMT-2030.
It should be noted that this Recommendation is defined considering the development of IMT to date based on Recommendation ITU-R M.2083 (approved in September 2015).
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 sections a brief overview of emerging technology trends, technologies to enhance the radio interface, and technologies to enhance the radio network are presented.
An important breakthrough in 3GPP Rel-17, Technical Specifications for Non-Terrestrial Networks (NTN) were established & defined for satellite direct access to device for both 5G and IoT services. This development reflects a trend that satellite & space technologies can offer many benefits for development & operation of future IMT-2030 networks, to enable 5G & 6G available everywhere, accessible to enterprises and citizens across the globe.
IMT-2030 will consider an AI-native new air interface that refers to the use of AI to enhance radio interface performance such as symbol detection/decoding, channel estimation etc. An AI-native radio network will enable automated and intelligent networking services such as intelligent data perception, supply of on-demand capability etc. Radio network to support AI services is 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. The integration of sensing and communication functions in future wireless systems will provide beyond-communication capabilities by utilizing wireless communication systems more effectively resulting in mutual benefit to both functions. Integrated sensing and communication (ISAC) systems will also enable innovative services and applications such as intelligent transportation, gesture and sign language recognition, automatic security, healthcare, air quality monitoring, and solutions with higher degree of accuracy. Combined with technologies such as AI, network cooperation and multi-nodes cooperative sensing, the ISAC system will lead to benefits in enhanced mutual performance, overall cost, size and power consumption of the whole system.
Computing services and data services are expected to become an integral component of the future IMT system. Emerging technology trends include processing data at the network edge close to the data source for real-time response, low data transport costs, energy efficiency and privacy protection, as well as scaling out device computing capability for advanced application computing workloads.
Device-to-device (D2D) wireless communication with extremely high throughput, ultra-accuracy positioning and low latency will be an important communication paradigm for the future IMT. Technologies such as THz technology, ultra-accuracy sidelink positioning and enhance terminal power reduction technology can be considered to satisfy requirements of new applications.
Energy efficiency and low power consumption comprises both the user device and the network’s perspectives. The promising technologies include energy harvesting, backscattering communications, on-demand access technologies, etc.
To achieve real-time communications with extremely low latency communications, two essential technology components are considered: accurate time and frequency information shared in the network and fine-grained and proactive just-in-time radio access.
There is a need to ensure security, privacy, and resilient solutions allowing for the legitimate exchange of sensitive information through network entities. Potential technologies to enhance trustworthiness include those for RAN privacy, such as distributed ledger technologies, differential privacy and federated learning, quantum technology with respect to the RAN and physical-layer security technologies.
