A generalized methodology for frequency reuse in autonomous cellular networks

This paper proposes a generalized methodology for frequency reuse in future cellular networks. These networks are equipped with a mixture of access points (APs) in different sizes and power capabilities. Some (or all) of the APs are deployed autonomously which results in an irregular deployment pattern. We first generalize the concept of a frequency reuse cluster - originally proposed for traditional cellular networks. Subsequently, adaptive clustering of APs is proposed based on which a resource allocation methodology is presented. Finally a hierarchical design framework with four levels of abstraction is introduced.
