UAV-BS Integration with Urban Infrastructure: An Energy Efficiency Prespective

The integration of uncrewed aerial vehicles (UAVs)with fifth-generation (5G) cellular networks has been a prominentresearch focus in recent years and continues to attract significantinterest in the context of sixth-generation (6G) wireless networks.UAVs can serve as aerial wireless platforms to provide on-demandcoverage, mobile edge computing, and enhanced sensing andcommunication services. However, UAV-assisted networks presentnew opportunities and challenges due to the inherent size, weight,and power constraints of UAVs, their controllable mobility, andthe line-of-sight (LoS) characteristics of communication channel
