However, achieving the ultra-reliable and low-latency communication capacity promised by 6G is not possible with fixed base stations alone. In particular, environments such as densely populated areas, disaster areas, rural areas, and hard-to-reach areas are among the scenarios where fixed infrastructures are inadequate.
All these studies indicate that drone base station technology will play a significant role in the future of mobile communication networks. Therefore, research activities in this area continue to increase. 2. Technical Background of UAV Deployment Optimization and Base Station Communication 2.1. General Structure of UAVs
