The cellular heterogeneous networks (CHNs) are of great interest for the great potential of improving the network capacity by employing low-power, easy- deployment short-range mini-base stations (BSs). To cope with the challenge of inter-layer/inner-layer interference environment in such heterogeneous architecture, we introduce cognitive Radio (CR) in CHNs, and named it as CR Enabled cellular heterogeneous...
As the demand for mobile data services skyrockets and the scarcity of spectrum increasing, femtocell networks overlaying with macrocell networks becomes a promising solution. However, the dense and random deployment of femto-cells and their uncoordinated operations cause severe inter-cell interference. This paper studies cluster-based wireless resource management issues in ultra-dense networks (UDN)...
