Green Mesh Networks for Unconnected Area Coverage and Proof of Digital Twins
The recently released ubiquitous connectivity scenario in the global 6G vision does not directly include 5G non terrestrial networks that are still in the experimental stage,although the challenge of"Connecting the Unconnected"has always been a research hotspot.We believe that a potential trend in 5G non ground network architecture is green and flexible,which has the potential to appear in the later 6G stage.In order to enhance the green and flexibility of integrated ground-air-space systems,a green mesh architecture on the ground is specially considered here.A digital twin modeling method and proof of concept within its capabilities are designed,the re-newable energy at the micro base station,the operation of Internet of Things(IoT)equipment and the wireless resource allocation strategy are modeled,and an accurate data-driven energy efficiency prediction scheme based on Transformer is developed and evaluated.The preliminary network architecture and proof of concept of wireless access will benefit the early feasibility study of digital twin satellites and provide reference for the future development of 6G space-air-ground integrated network.5G non-terrestrial networks are still in the early exploration stage,but its innovative concepts in green,flexibility and sustainability are highly matched with the development direction of 6G networks.It is verified that non-terrestrial networks have broad application prospects in the 6G era through digital twin modeling method.
