In January 2025, ETSI established a new Industry Specification Group (ISG) focused on Multiple Access Techniques (MAT) for 6G mobile systems. CTTC along with major industrial players (BBC Research, VIAVI, etc.) and a number of academics is a founding member and regular contributor to this ISG. The group aims to build industry consensus on innovative multiple access techniques, based on 3GPP specifications. Specifically, the ISG MAT will explore candidate techniques such as Orthogonal Multiple Access (OMA), Spatial Division Multiple Access (SDMA), Non-Orthogonal Multiple Access (NOMA) and Rate-Splitting Multiple Access (RSMA) that enhance the transmission efficiency across parameters such as spectrum efficiency, power consumption, latency and user fairness. Relevant deployment environments considered in the ISG MAT are indoor hotspot, urban macro (e.g., High Demand Density areas) and rural settings. The ISG MAT will concentrate on downlink multiple access techniques for the physical layer of the 3GPP radio interface, for unicast-only delivery, and joint broadcast/multicast and unicast delivery services. The new ETSI Group will deliver Group Reports to be considered by 3GPP and other relevant industry bodies in their 6G standardization activities.
