Spectrum management has been identified as a crucial step towards enabling the technology of the Cognitive Radio Network (CRN). Most of the current works dealing with spectrum management in the CRN focus on a single task of the problem, e.g., spectrum sensing, spectrum decision, spectrum sharing or spectrum mobility. In this work, the authors argue that for certain network configurations, jointly performing several tasks of the spectrum management improves the spectrum efficiency. Specifically, they study the uplink resource management problem in a CRN where there exist multiple Cognitive Users (CUs) and Access Points (APs), with each AP operates on a set of non-overlapping channels.
