![](https://www.6gworld.com/wp-content/uploads/2022/08/Leo-SAN-1024x507.png)
This paper aims at revealing the main technical issues that have not been fully addressed by the existing LEO-SAN designs, from three aspects namely random access, beam management and Doppler-resistant transmission technologies. Promising technologies to address these challenges are also discussed, respectively. Finally, the future research directions are envisioned.
