Abstract
To address the escalating demands for wideband communications and network densification, a novel approach involving millimeter-wave (mmWave) enabled integrated access and backhaul (IAB) is imperative for the sixth generation (6G) cellular Internet of Things (IoT) network. However, the introduction of mmWave-enabled IAB technology poses challenges to network capacity, specifically related to the varied backhaul capacities of small cell base stations and the diverse interferences among access links in the 6G cellular IoT network. In response, this paper presents a joint framework for traffic load balancing and interference mitigation with the goal of maximizing the network capacity for 6G cellular IoT services. Additionally, to minimize both backhaul burden and interference, a novel matching utility function, considering backhaul capacity and interference, is designed using the many-to-many matching model. The non-convex power allocation subproblem is transformed into a convex problem us
