Integrated Sensing and Communication (ISAC), regarding as an important 5G-A and 6G (Radio Communication Technology (02) 2021, J. Beijing Univ. Posts Telecommun, (04)2021, Theor. Technol. Integr. 6G Commun. Sens Control. Decis, 38(1), 22–38 (2023) technical aspect, has currently met a break though from academic research to industrial implementation. The development of this technology marks a significant transition from theoretical research to practical application, paving the way for the intelligentization of future communication networks. This paper first outlines the air interface design scheme for ISAC in three typical scenarios of low-altitude airspace, waterway and sea area, through three steps: analysis and design of sensing waveform, transmission time slot for sensing signals, and sensing waveform parameters. Secondly, the paper gives out the lab test results of the ISAC air interface design scheme. Finally, it briefly introduces the three aspects that still need to be considered and solved for further commercial use: reducing system overhead, improving sensing performance, and reducing network interference.
