The 6G Architecture and System Design working group brings together the developed solutions and integrates them into an overall solution and architecture that also takes into account possible backward compatibility with 5G and migration paths to other technologies. External solution approaches that can be integrated into the Open6GHub solution are also identified here. Societal requirements and especially the aspects of sustainability and energy efficiency will be an important design criterion for which – as far as possible – a quantitative evaluation methodology will be developed. This is especially true for energy efficiency and exposure. In the architecture definition, advantages and disadvantages of a stronger fragmentation of the RAN and opening of the mobile system (performance, energy efficiency, integration aspects, openness, security aspects, …) including the implications for the interfaces will also be considered. The overall design process in the Open6GHub is carried out with the participation of the associated technology advisory board, so that the recommendations of the technology advisory board can be incorporated.
With regard to the performance analysis and spectrum utilization concepts and spectrum requirements, a close cooperation with the BNetzA is intended and the German contributions to the ITU-R process as well as the WRC2023 and the preparatory phases are to be supported.
