In a significant move for the mobile telecommunications industry, the European Telecommunications Standards Institute (ETSI) has unveiled a new Industry Specification Group (ISG) dedicated to Multiple Access Techniques (MAT) for the next generation of mobile systems, commonly referred to as 6G. This initiative aims to unify various stakeholders in the industry to work collaboratively on defining and refining techniques that will uplift the performance and efficiency of future wireless networks.
Exploring New Frontiers in Connection
The newly established ISG MAT intends to examine an array of potential techniques aimed at enhancing transmission efficiency, which covers various vital factors, such as spectrum usage, power consumption, latency, and user equity. Among these techniques are Orthogonal Multiple Access (OMA), Spatial Division Multiple Access (SDMA), Non-Orthogonal Multiple Access (NOMA), and Rate-Splitting Multiple Access (RSMA). Each of these approaches brings a unique strategy for managing how multiple users can effectively share the same communication resources.

This industry group focuses on several scenarios where these techniques could be applied, including urban hotspots, high-demand urban areas, and rural locations. The primary emphasis will be on downlink multiple access technology at the physical layer, which is crucial for ensuring robust communication between base stations and user devices.
The ISG MAT was officially launched during a meeting held on January 15-16, 2025, in London, where participants included representatives from industry, academia, and government. The event saw the election of Dr. David Vargas from the BBC as the chairperson, alongside Prof. Bruno Clerckx from Imperial College London and Dr. Stephen Wang from VIAVI Solutions serving as vice chairs.
Leadership Speaks: The Importance of Multiple Access Techniques
Dr. David Vargas underscored the importance of Multiple Access Techniques in shaping the future of mobile communications. “Multiple Access Techniques are at the core of mobile technology development and are considered a key technology to enhance the radio interface for IMT-2030 systems,” Vargas stated. “We are thrilled to launch the ISG MAT, bringing together industrial and academic experts in a shared mission to accelerate the advancement of innovative Multiple Access Techniques for 6G mobile systems.”

2. Performance Measurement: Establishing key performance indicators and evaluation methods that will help gauge the effectiveness of these new techniques.
3. Processing Structures Analysis: Investigating the complexities involved in transmitter and receiver processing, crucial for ensuring effective communication.
4. Physical Layer Studies: Assessing procedures at the physical layer that impact overall system performance.
5. Impact on Specifications: Analyzing how new multiple access techniques may affect existing specifications and the potential gaps that might arise.
6. Prototype Development: Creating proof-of-concept models and engaging in field trials to validate the effectiveness of proposed methods.
Setting the Stage for the Future of Connectivity
The ISG MAT is committed to producing reports for the 3GPP and other influential industry groups involved in shaping 6G standards. The group’s work will contribute to building a robust communication framework capable of supporting a multitude of applications, from immersive interactive experiences to improved connectivity solutions in densely populated areas. This forward-looking initiative is expected to pave the way for more efficient media delivery, enhancing both live and on-demand content over mobile networks.
As the world eagerly anticipates the rollout of 6G technology, the formation of the ISG MAT signals a proactive approach to addressing the complexities of modern communication. By fostering collaboration across various sectors, ETSI aims to ensure that future mobile systems can meet the ever-increasing connectivity demands of a digital and interconnected world.
In summary, the launch of the ISG MAT marks a significant step in preparing the telecommunications landscape for 6G, focusing on collaborative efforts to develop advanced multiple access techniques that promise to redefine how we connect.
