随着广域物联网（Internet of things,IoT）的出现，为了在广阔地理区域上实现无缝连接的需求，提出了一种新型的去蜂窝非地面-地面混合网络。该系统利用非地面网络（non-terrestrial network,NTN）设备的2种不同部署模式实现了广域物联网的全球覆盖，其中NTN设备既可以作为无线接入点又可以作为无线中继。针对2种部署模式分析了2者的区别，并分别提出其相应的部署场景。随后通过案例分析，评估了所提方案的可行性，表明了它可以提高系统的能量效率和通信效率。通过所提方案，系统提高了超过7倍的能量效率和通信效率。最后对其面临的机遇、挑战以及未来研究方向进行了讨论和展望。
Abstract：With the emergence of wide-area Internet of things(IoT) applications, a novel cell-free hybrid non-terrestrial-terrestrial network is proposed to meet the need for seamless connectivity across vast geographic regions. The system leverages two distinct deployment modes of non-terrestrial network(NTN) devices to achieve global coverage,where the NTN devices function either as wireless access points or as wireless relays. The differences between these two deployment modes are analyzed, and appropriate deployment scenarios are discussed for each. A case study is conducted to evaluate the feasibility of the proposed system. The results indicate notable improvements in both energy efficiency and communication efficiency. Specifically, the proposed scheme achieves more than a sevenfold increase in both metrics. Finally, the potential opportunities, challenges, and future research directions of the system are discussed.
