To promote a secure communications environment across multiple Socio-Economic settings based on user needs and requirements
WGA is focused on discovering and promoting research areas that strive to understand the needs for and requirements to wireless future internet systems. The activities are based on the understanding that users are driving the creation and design of new, emerging applications and services in a secure environment. This includes the ‘direct’, traditional user requirements area: how the users are driving the creation and design of new, emerging services in a secure environment and how users will interact with devices, systems and applications in the Wireless World. It also includes ‘indirect’ user requirements in the form of ‘M2M’ communications. There is thus recognized an Increasing socio-economic impact on the Wireless development where the Future Internet will represent an increasing fusion between the digital and the physical world. User acceptance of this development requires attention to data protection, privacy and ethical issues. WGA addresses these challenges and investigates the sphere of user requirements and interaction between users, devices, systems and applications and studies the elements of viable business models under different socio-economic conditions.
Focus in 2023 – Preparing for the CMI/ WWRF conference 16/ 17 November 2023 in Copenhagen work will in collaboration with WG Cybersecurity focus on discussing/ analyzing data collection and privacy in connected cars.
The approach and focus of the WWRF is at present being sharpened to better align with the technology innovations and industry directions in networking and communication. As a result, the Working Group C, while building on its successes, is being revitalized to speed-up and facilitate the convergence of software, cloud, big data, virtualization and networking. It is the WGC’s endeavor to pool industry and academic resources to do targeted applied research to identify challenges facing the industry with this convergence and propose solutions that are pragmatic in the short-term (with backwards compatibility) and strategic in the long-term to evolve to what ideally they should be.
The group’s mission is to guide the mobile industry in the use of software, virtualization and cloud computing in future networks (both wireless and wired) by developing end-to-end network architectures, identifying the specific requirements and issues and addressing them by providing solutions that are practical and business driven, and thus accelerate the adoption of 5G where IT will play a major role. Virtual network slicing to develop custom networks for specific industry verticals and services from the common underlying physical infrastructure will also be an important mission of this group.
In short, the group focuses on Internet of senses, softwarization, cloudification, virtualization and slicing of the 5G and future networks (such as 6G) where IT will play an important role
Main topics that WGC covers are focused on:
WGD addresses research aspects focusing on the air interface for wide-area and local-area wireless communication systems, the Internet of Things and the Internet of Senses, spectrum issues and resources management and sharing.
WGD covers topics such as smart antenna technologies, cooperative communications, interference management and cell-less architectures, Reconfigurable Intelligent Surfaces and Joint Communications and Sensing. Physical-layer security of wireless systems is also covered in this working group.
As wireless networks evolve towards IMT-2030 and beyond, connectivity will be faced with new challenges stemming from critical usage scenarios, both as extreme evolution of well-known 5G usage scenarios (MBB, URLLC, MMTC) and as revolutionary usage scenarios with a clear emphasis on ‘beyond communications’ characteristics. Especially for the latter, capacity and latency may not be the only critical performance targets. Reliability, resilience, and reconfigurability are expected to play a significant role in performance optimization. The objectives of reliable and efficient transmission of bits may be further expanded to also address sensing, situational awareness, as well as immersive and interactive intelligence. Balancing performance with scalability/complexity may prove an important challenge in future networks.
It is envisaged that WGD will address a large dynamic range of modelling, analytical assessment, advanced radio technologies design, physical layer procedures and resource management approaches, including (but not limited to) the following topics:
Advanced modulation, coding and multiple access schemes
Advanced antenna technologies
Propagation and channel modelling
Reconfigurable Intelligent Surfaces
Electromagnetic Information Theory
Integrated sensing and communication
Ultra-high accuracy positioning
Full duplex communications
mmWave and THz communications
Ultra-dense radio technologies
Physical layer security
Spectrum management algorithms and techniques
Standardization and regulatory aspects
WGD has been following and contributing to the works of ITU-R WP5D and has been driving the technical contributions of WWRF as sector member of ITU towards IMT-2020 Evaluation and IMT-2030 Technology Trends and Vision.

Workshop on Cybersecurity on 1st April 2022
With the mission to promote a trusted and cyber secure environment for the current and future wireless technologies through the identification of key research challenges and technology trends WWRF organised a virtual workshop on 1st of April, WWRF WG-Cybersecurity on “Cybersecurity in 5G Beyond” The workshop had good representation from the Industry and Research Institutions. The topics for the talks were:
WWRF provides a platform to the global wireless research community to explore and develop the research challenges that confront us as we look beyond current 5G and other developments. These developments have raised considerable concerns in the cybersecurity sector.
WG-Cybersecurity focuses on addressing these concerns and provides a common ground to researchers and Industry representatives to explore these challenges. The group takes the multifaced approach to cybersecurity due to its complexity as there are multiple threat vectors, increasingly sophisticated and effective attacks, and a general lack of suitable security standards.
To support our mission of “a trusted and cyber secure environment for the current and future wireless technologies” the WG-cyber will focus on following areas.
Focus in 2023 – Preparing for the CMI/ WWRF conference 16/ 17 November 2023 in Copenhagen work will in collaboration with WG A/B focus on discussing/ analyzing data collection and privacy in connected cars.
While the wireless world is moving towards the 6G era and many technological advances have been proposed, there seem to be significant limitations in the capability to efficiently and flexibly handle the massive amount of QoS/QoE-oriented data that will be exchanged along with the super-high data rate and almost zero latency requirements. Moreover, there is a clear trend towards perceptive and resilient connectivity, where situational awareness, resilience, sensing agility and reconfiguration intelligence will transform wireless networks towards a ‘beyond just communications’ era.
THz connectivity (above 100GHz) as a wireless backhaul extension of the optical fiber is an important building block to high-speed internet access everywhere in 6G. Furthermore, new challenging THz connectivity scenarios are becoming ever more relevant in 6G systems, including: NLOS connectivity based on metasurfaces with the capability to dynamically reconfigure so to track slowly moving users and Ad hoc connectivity in fast moving network topologies, e.g., based on drones or V2X links. Holographic MIMO and Large Intelligent Surfaces in the THz regime offer the potential of shaping/tuning the wireless environment by taking advantage of the wavefront engineering capabilities. Most important, THz wireless connectivity provides an ideal playground for joint communications and sensing, environmental mapping and localization/positioning.
Together with extraordinary promises, THz communications bring unique and novel challenges that require rethinking classic communications and networking mechanisms. The root cause for these challenges is the ultra-wideband, the distance dependent bandwidth and the extremely directional nature of THz communications links. Other peculiarities of THz communications include signal and antenna design, channel, and interference modelling. The fundamentally different structure of the interference, due to narrow beams, calls for thorough investigation and detailed modelling of interference. Medium access control (MAC) and radio resource management (RRM) protocols now must operate with pencil beams and, thus, have to be based on completely new principles. Fast handover procedures need to include the time required for discovery, localization and tracking functionalities. The Tbits/s data rates create significant challenges for the transceiver processing including algorithm and architecture design as well as hardware implementation.
Motivated by the potential of THz technologies to transform the future of ICT, WG-HF aims to identify the critical technology gaps as well as the appropriate enablers, in terms of baseband processing RF frontend, channel models and waveforms, signals and coding, beam-patterns and medium access control schemes. It aspires to provide a discussion platform/thinktank, by engaging a critical mass of experts from industry, regulators and academia, in order to investigate/understand the trends, requirements, enablers and challenges in the specification, design, optimization and adoption of above 100GHz radio technologies in future wireless networks.
The topics of interest include (but are not limited to) the following:
Transceivers for terahertz communications
Antenna and ultra-massive antenna arrays for Terahertz communications
Electromagnetic Information Theory for Terahertz communications
Channel models for Terahertz communications
Channel estimation techniques for Terahertz communications
Modulation and waveform design for Terahertz communications

MAC layer design for Terahertz communications
Interference management for Terahertz communications
System-level modelling and experimental demonstrations
To peer into what is next to come after 5G (B5G) leading to the development of the standards for 6G, required research into the enabling technologies and how it is likely to be commercialized. Nothing succeeds without the compelling use cases, applications, and innovations in business models; therefore, this group will also be vigilant about these non-technical aspects to augment its work on technologies and standards to present a holistic view of the launch of the 6G era.
The 6G Vision and Technologies Group focuses on research that looks five to ten years ahead in order to meet the requirements of the networks in the year 2030 time-frame. The group looks into the gaps in 5G that would need to be filled, resulting into incremental changes to 5G, called B5G until such time that clear requirements of 6G have been determined and needed research areas identified. The group also aims to study the emerging new use cases that will require 6G, and the potentially novel business models to justify investments that will be needed.
Areas of focus
The major companies, universities and organizations active in 5G, B5G and 6G are most welcome to join the 6G Working group.
Develop an e/m-Health and wearables vertical industry paradigm to expose the requirements of such systems (HaaS) to be 5G enabled. Get the experts from this vertical industry involved in the WWRF VIP and beyond.
The objectives of the e/m-Health and wearables Vertical Industry Platform (VIP) are to:
Figure 1. 5G in e/m-Healthand wearables
The above objectives will be realised by investigating various evolutions in healthcare by selecting a specific domain and focusing on the following:
Case study parameters (and KPIs)
Stakeholders approached (and we have positive feddback)
The Vertical Industry Platzform (VIP) Rail study group focuses on research that looks five to ten years ahead to meet the requirements of the railway industries based on the next generation wireless technologies. It is also aimed to identify and discuss new and vital use cases for these industries.
As the global process of developing the 5G (NR) platform is progressing at remarkable speed, both in terms of the identification of the market need, standardization aspects and spectrum related matters, where sets of “pioneer bands” already has been adopted across Regions, a need is emerging to focus more closely on the Professional Sectors, in this case the national Train Service Authorities, and the potential benefits and hurdles for their future adoption of what today is known as 5G.
As train services across the world offer higher speed trains, the need for operational radio communications systems and Internet of Things (IoT) are also pushing this aim.
Security, reliability, safety, resilience, IoT and dependability are playing a focal role in future radio communication systems for efficient train operations.
Furthermore, VIP Rail study group should also consider participation in the ITU-R activities, that are being initiated based on the decisions of the ITU-R World Radio Conference 2019regarding choice of harmonized spectrum for train to track communications.
Milestones and deliverables
Outputs include white papers and technical proposals which will be submitted to the major standardization bodies of 5G, including ITU and 3GPP.
