Existing directed acyclic graph (DAG) based IAB networking highly limits the flexibility and efficiency of link scheduling, due to the fixed parent-to-child relation between two adjacent IAB nodes. In this project, a mesh-architecture based approach is developed to improve the efficiency of IAB networking. The key idea of the mesh architecture is to make the relationship between two adjacent IAB nodes configurable. Based on the mesh architecture, the two-stage scheduling scheme of IAB networks is revised.
