本文介绍一种新型的数能一体化无线通信网络，它将传统的无线网络中相互独立的无线信息传输和无线能量传输融合起来，实现数据和能量的协作同传。传统的无线携能通信侧重在物理层进行，本文所提出的数能一体化网络则强调系统性，在网络各层设计并实现相应的协议和资源分配。与其他再生能源如风能太阳能等不同，数能一体化网络 DEINs 中的能量源，即基站的射频（RF）信号，不受自然环境的影响，而且完全可控。数能一体化网络在解决无线通信系统的能效问题、实现无线通信的节能减排方面具有巨大的潜力。本文从两个方面阐 述所提出的数能一体化网络：能量和网络。在能量方面，本文介绍并分析了数能一体化网络的能量编码、能量模型、能量管理等。在数据网络方面，本文对数能一体化网络的各层讨论了几种核心技术，包括物理层、数据链路层协议及联合资源分配、网络层以及数能一体化网络的典型网络应用场景。在各层的介绍中，本文着重于新方向的讨论，而非现有研究工作的简单重述。最后，本文对该领域未来的发展趋势和研究方向作了总结和展望。 This paper introduces a new type of digital and energy integrated wireless communication network, which integrates the independent wireless information transmission and wireless energy transmission in the traditional wireless network, and realizes the cooperation and simultaneous transmission of data and energy. The traditional wireless energy communication focuses on the physical layer, but the digital energy integrated network proposed in this paper emphasizes systematicness, and the corresponding protocols and resource allocation are designed and implemented at each layer of the network. Unlike other renewable energy sources such as wind and solar power, the power source in DEINS, namely the radio frequency (RF) signal from the base station, is not affected by the natural environment and is completely controllable. Digital and energy integration network has great potential in solving the energy efficiency problem of wireless communication system and realizing the energy saving and emission reduction of wireless communication. In this paper, the proposed digital energy integration network is described from two aspects: energy and network. In terms of energy, this paper introduces and analyzes the energy coding, energy model and energy management of digital energy integrated network. In terms of data network, several core technologies, including physical layer, data link layer protocol and joint resource allocation, network layer and typical network application scenarios of digital energy integrated network, are discussed in each layer of log-energy integrated network. In the introduction of each layer, this paper focuses on the discussion of new directions rather than a simple restatement of existing research work. Finally, this paper summarizes and forecasts the development trend and research direction of this field in the future.
