Unmanned aerial vehicle assisted communication: applications, challenges, and future outlook

With the advancement of wireless communication technology, the number of wireless network terminals has exploded, and various new business scenarios have emerged. The 6G mobile communication technology not only surpasses 5G standards in terms of transmission rate, delay, power and other performances, but also extends the communication range to multiple fields such as air, ground, ocean, etc., which greatly promotes Unmanned Aerial Vehicle (UAV) communication technology research and development. Compared to terrestrial networks, UAV communication has advantages such as high flexibility and easy deployment. However, there are still many problems and challenges in practical applications. In this paper, we will first introduce the functions and application scenarios of UAV communication, then discuss the current challenges and related technical research, and finally look forward to the future development prospects.
