In Cognitive Radio (CR) networks, the licensed but vacant spectrum bands are shared by the unlicensed users (CR users) in an opportunistic manner. The CR users should operate and cohabit in the licensed bands without causing any interference to the Primary Users (PUs). This CR user cohabitation which is managed by a spectrum coordinator, enables several design challenges. Therefore, a User Cohabitation Coordinator, UCC, should be designed considering the heterogeneous Quality of Service (QoS) requirements for the CR users and the short-term fluctuations in the available licensed spectrum bands.
