A Review on Unmanned Aerial Vehicle-based Networks and Satellite-based Networks with RSMA: Research Challenges and Future Trends

Unmanned aerial vehicles (UAVs) and Satellites are promising as power frameworks for 5G and 6G networks to provide solutions for the limitation in deployment, batteries, and transference reliability in areas. It leads to efficiency in terrestrial systems, broken Base stations (BSs) substitution, reduced cost infrastructures, and mobility management. It is also an indispensable role to improve the quality of Internet Of Things (IoTs) systems. Besides, Rate-Splitting Multiple Access (RSMA) has emerged as a promising technique to manage interference in multiple access (MA) systems, and optimize the non-orthogonal transmission (non-OT) for 5G and 6G networks. In the current, one of the most impressive schemes for the Unmanned Aerial Vehicle (UAV) and Satellite-based networks is RSMA. This paper details a comprehensive review on UAV and Satellite networks with RSMA of wireless network 6G. After analyzing the overview of UAV and Satellite-based networks with RSMA, the main applications of RSMA scheme in networks based on UAV and Satellite-based networks will be exploited. Finally, the main challenges and future directions are suggested and defined.
