About this paper
Bin Li, Zesong Fei, Yan Zhang
This survey provides a comprehensive review of Unmanned Aerial Vehicle (UAV) communications for 5G and beyond 5G networks, proposing the Space-Air-Ground Integrated Network (SAGIN) architecture. It synthesizes recent advancements in applying 5G technologies across physical, network, and joint communication/computing/caching layers to UAV platforms, while also identifying key challenges and future research directions.
Key insights
- UAVs offer crucial advantages like flexible deployment, strong Line-of-Sight (LoS) links, and controlled mobility, making them essential for augmenting and extending 5G/B5G network capabilities.
- The envisioned Space-Air-Ground Integrated Network (SAGIN) architecture, managed by Software-Defined Networking (SDN), provides a scalable and robust framework for future heterogeneous wireless communications.
- Realizing the full potential of UAVs in 5G/B5G requires addressing substantial challenges related to channel modeling, 3D deployment, energy efficiency, interference management, and security.
