Unmanned aerial vehicles(UAVs)can be rapidly and cost-effectively deployed.By deploying the base station equipment to the launching UAV platform,the air-ground networks of UAVs can quickly build ground coverage network from the air,so it has broad application prospects in emergency relief,remote area coverage,intelligent transportation,smart city,and other aspects and has received wide attention in recent years.Based on the application scenario of air-ground networks of UAVs,the characteristics of UAVs'maneuver,network,and load were considered.From the four dimensions of coverage performance improvement of air-ground networks,integrated communication-sensing-calculation design of air-ground networks,reconfigurable intelligent surfaces(RIS)-assisted air-ground networks,and robust air-ground networks of UAVs,the research status of air-ground networks of UAVs was reviewed in terms of network scenarios,key technical challenges,and performance optimization control methods.In addition,the future research direction of optimizing the performance of air-ground networks of UAVs was explored.
