英文摘要： Due to the advantages of environment friendliness, easy and flexible deployment, utilizing renewable energy for wireless communications has attracted extensive attentions recently. Currently, the research on the wireless communications under renewable energy is under its infant stage, which is far from practical applications. In order to combat the impacts of the randomness and unstableness of the renewable energy on sustaining the quality of communications, this project targets at guaranteeing the quality of service through energy management for wireless networks. Specifically, we focus on the coordination of the dynamic energy harvesting and wireless resource allocation, the renewable energy and power grid energy, and the way of using harvested energy among various transmission nodes. We plan to conduct the following research work: (1) For single link transmission, we jointly optimize the resource allocation of power, adaptive modulation and coding, and multiple antennas under the dynamic energy harvesting. (2) For the network consisting of heterogeneous transmission nodes with different energy harvesting modes and capabilities, we optimize the node planning, and then based on the dynamic energy arrival, we design node cooperative transmission schemes. The outcome of our research can provide valuable technical
