Abstract

Abstract:

In order to realize anytime and anywhere communication, low earth orbit (LEO) satellite communication becomes a key component in 6G.Through the adaptive enhancement of terrestrial mobile communication protocol, LEO satellites can provide direct connection services for mobile phones.The related key technologies and the recent progress of various commercial programs were introduced, and future issues were also identified together with potential technical solutions.

Key words: low earth orbit satellite communication, direct connection between satellites and mobile phones, integrated satellite-terrestrial network
