As wireless EH communication systems are different from traditional communication systems, we need new models and policies to achieve an optimal balance between the quality of service, performance, and efficient use of energy. Based on prophase investigation and research, we plan to carry out the policy studies of the data and energy cooperation in several typical scenarios of wireless EH cooperative communication systems, including the multiuser communication scenarios, the MIMO transmission scenarios, and the distributed cooperation scenarios. To be specific, in the multiuser communication scenarios, the data and energy cooperation will be considered when the information of users comes from multiple source nodes. For different users, the resource allocation at the source and the relays, the slot designs, the cooperative policy and the energy-saved relay selection will be dealt with, respectively. In the MIMO transmission scenarios, we will consider the data and energy antenna selection on which the data and energy cooperation depends. Besides, other data and energy cooperative schemes, different from the antenna selection ways, will be investigated and compared for the multiuser MIMO transmission. In the distributed cooperation scenarios, the cooperative models in the intra-cell and inter-cell areas, in terms of the distributed relay nodes and distributed ports, will be established for the investigations on the energy sharing mechanism and corresponding data and energy cooperation methods, and also for the similarities and differences of two cooperation modes on the working principles, the applications and the implementations. In conclusion, this project has been prepared according to the sufficient research basis, clear research goals and scientific and rational research content. The results out from our studies will be beneficial to solve the emerging problems of the data and energy cooperation, and design the practical wireless EH cooperative communication systems.
