In this paper, the authors investigate resource block assignment in femtocell networks. A resource block assignment algorithm is considered to avoid co-channel inter-cell interference and ensure service quality for femtocell networks with dense and random femto deployments. They first formulate the optimization problem as the Integer Linear Programming (ILP) on resource block assignment. The goal of the optimization problem is to maximize the overall utilization of resource blocks with Quality of Service (QoS) constraints. They propose an efficient and simple algorithm termed Interference-Aware Resource Block Assignment (IARBA).
