In cellular networks, the base station (BSs) is obligated to more than 50% energy consumption of the networks. Therefore, reducing the power consumption of BSs is crucial to enhance the energy efficiency of cellular networks. Cognitive radio, an enabling technology, is a new system design paradigm for next cellular networks. In this paper, we proposed an optimal bandwidth sharing based on the selection scheme which exploited the cooperation between multiple primary base stations (PBSs) and several secondary base stations (SBSs) to enhance the spectrum as well as energy efficiency of cellular networks
