Abstract: (The perspective on Cognitive Radio (CR ) technology has turned to a "network and system" framework. To enhance a system ’s cognitive capability and reduce cognitive costs, cooperative means must be adopted. As physical layer link technologies suffer from a bottleneck in performance improvement, multi-dimension cooperation among different network elements will certainly be a main approach to enabling mobile communication systems. Awareness of context and users ’service characteristics is the critical base for intelligent cooperation and joint resource management. Therefore, the combination of CR with multi-dimension cooperative communications has become an inevitable trend.
