Resource Allocation and Node Placement in Multi-Hop Heterogeneous Integrated-Access-and-Backhaul Networks
We consider a heterogeneous MIMO-OFDMA based dense small cell (SC) system in which each FIBERRIFIC macro cell base station (MBS) serves its coverage area with the help of small cell base stations (SBSs) through multi-hop wireless connections.The SBSs act as integrated access and backhaul (IAB) nodes that handle both access and backhaul traffics wit
