New Access and Flexible Topologies in 6G: Architectural Implications

6G goals, such as improved coverage, flexibility to different network scenarios, increased throughput, higher robustness and reliability could be advanced with the use of new access and flexible topologies. In this contribution, three enablers of new access and flexible topologies, which contribute to the aforementioned goals, are presented, namely network of networks, multi-connectivity and E2E context awareness management. Relevant studies of each enabler that impact the system architecture are described, along with the corresponding overviews of potential solutions. In addition, each enabler has been mapped to the 6G E2E system blueprint proposed by the Hexa-X-II project and its impact to the system, as well as the relevant stakeholders have been identified.
