Integrated sensing and communication for low-altitude network
With the rapid development of emerging technologies such as unmanned aerial vehicles(UAVs)and intelligent logistics,the low-altitude economy is gradually becoming a new engine for driving economic growth.Integrated sensing and communication(ISAC),as an important feature of future mobile communication networks,can provide new capabilities such as detection,regulation,tracking,and obstacle avoidance for low-altitude targets on the basis of communication,promoting the vigorous development of low-altitude services.This paper explores the demand for ISAC technology in the development of low-altitude economy,and analyzes five key issues:insufficient wide area coverage,limited sensing accuracy,insufficient sensing credibility,complex and difficult global interference,and lack of systematic technical indicators in sensing.Corresponding technical solutions are proposed,which can serve as a reference for research and practice in related fields.
