Abstract:
Mesh connectivity among mobile base stations could offer the ultra-low latency required by diverse mission-critical use cases in 6G networks. We explore enabling such mesh connectivity through Integrated Access and Back-haul (IAB), which allows direct data communication whilst signalling and control could still go through the core network. In this paper, we assess the feasibility and evaluate the performance of mesh connectivity in RAN, through IAB and benchmark it with the current mobile network architecture in diverse scenarios. The results showcase an average of 46% reduction in the end-to-end latency, an average gain of 22% in end-to-end throughput and improved scalability due to its decentralised nature. The RAN mesh architecture, evaluated here, is presented in this paper as a step towards a core-less mobile network.
