针对具有能量收集（EH）的分布式天线系统（DAS）的能量共享问题，提出了一种能够在系统组件之间共享收集到的能量的分布式天线系统模型。与文献中现有的模型相比，该模型通过统一的接口与智能电网连接，有利于能源管理和调度。基于所提出的模型，分析了部分能量共享法、完全能量共享法和自维持能量共享法三种能量共享方法。在各种能量共享方法下，描述、形成并解决了相应的远程天线单元（RAU）之间的功率分配优化问题。由此得出了每种方法对应的功率分配算法。仿真结果表明，与现有模型相比，所提出的模型在信道容量和能量效率方面更加有效。
For the energy sharing problem of distributed antenna system (DAS) with energy harvesting (EH), a distributed antenna system model capable of sharing collected energy among the components in system is proposed. Compared with the existing model in literatures, the proposed model connects with smart grid through a unified interface and facilitates energy management and scheduling. Based on the proposed model, three kinds of energy sharing methods including the partial energy sharing method, the complete energy sharing method and the self-sustaining energy sharing method are analyzed. Under various energy sharing methods, the corresponding optimization problems of power allocation among the remote antenna units (RAUs) are described, formed and solved. As a result, the corresponding power allocation algorithm to each method has been concluded. Simulation results show that the proposed model is more efficient in terms of the channel capacity and energy efficiency, compared to the existing model.
