Joint association and resource allocation for multi-hop integrated access and backhaul (IAB) network

Integrated access and backhaul (IAB) network is envisioned as a novel architecture for increasing the capacity coverage. To facilitate IAB network, appropriate methods of wireless link association resource management are required. In this paper, we investigate joint optimization problem allocation in terms subchannel power network. particular, handle problems links considering multi-hop backhauling. Since formulated mixed integer non-linear programming (MINLP), divide it into three subproblems association, allocation, respectively, these solved alternatively to obtain local optimal solution. For problem, adopt Lagrangian duality approach configure successive convex approximation (SCA) used solve efficiently. Simulation results demonstrate that proposed algorithm achieves better performance than single-hop (SH) backhauling based enhances coverage by configuring (MH)
