Adaptive 6G RAN technologies

The working group aims to bring together technologies and functions for 6G radio (air interface) and 6G sensing, Joint (Radio) Communications & Sensing (JCAS), and to explore new architectures, methods and protocols aimed at application to high-reliability industrial radio solutions (6G Industrial Radio) and private and local area networks and network extensions (6G Campus Networks). In this context, the exploitation of the frequency ranges sub-6 GHz, 26 GHz to THz is addressed. The cornerstone for this is the development of a scalable 6G broadband test platform for 6G communication links (radio) and sensing of the radio network environment (sensing).

Techniques are explored to analyze the radio environment of a network in terms of active radio operations (subscribers, unconscious as well as conscious interference) as well as radio-independent contexts (objects, motion, structures) and to adapt/optimize the capabilities of the communication in an application-specific manner. Adaptive RAN features and protocols will enable the networks to act cognitively and anticipatory and to allow radio and network resource utilization. Optimized waveforms and algorithms for ultra-fast industrial radio communication (D2D & D2-Multi-Device, THz) and new 6G campus network system approaches and spectrum utilization concepts will be explored as well as backward compatibility to 5G networks and integration into public networks.
