5G Integrated Radio Transmission Scheme for Low Earth Orbit Satellite Access Network

This paper comprehensively analyzes the channel transmission characteristics of the low earth orbit satellite. On this basis, the problems when each physical layer process of terrestrial 5G new radio is directly applied to the LEO satellite access network is further analyzed, then the feasible implementation schemes for each 5G integrated physical layer process of the LEO satellite access network are carefully designed. Furthermore, the core technologies of each key step of each 5G integrated physical layer process are briefly discussed.
