财务和环境考虑提供了被称为绿色通信的无线通信网络中的新趋势。绿色通信的主要目标是在保证用户服务质量（QoS）的前提下尽可能地节省通信系统的能耗。在本文中，合作频谱共享作为一种节能的手段进行了研究。在服务质量约束下，提出了一种协作频谱共享网络中最优的功率和时间分配策略，以最小化网络的总能耗。所提出的技术可以实现节能，同时提供SU的通信机会。数值结果验证了该方法的有效性。
Financial and environmental considerations provide new trends in wireless communication network known as green communication. The main object of green communication is to save energy consumption of the communication system as much as possible with users' quality of service (QoS) guaranteed. In this paper, cooperative spectrum sharing is investigated as a means of energy saving. We present an optimal power and time allocation to minimize the overall energy consumption under service quality constraints in cooperative spectrum sharing network. The proposed technique can achieve energy saving while offering SUs' communication opportunities. Numerical results demonstrate the validity of the proposed technique.
