Key Competence Analysis of Non-Terrestrial Network-Based Cellular Backhaul

As the mobile communication developing from 4G to 5G, it is an important technical trend to develop cellular backhaul by using Non-Terrestrial Network (NTN). This paper introduces the requirement of transmission rate and time delay for eNodeB (eNB) and gNodeB (gNB), as well as the ability of transmission rate and time delay which Non-Terrestrial Network can provide. Then, the improvement scheme of UDP, TCP, SCTP and voice service that are affected by Non-Terrestrial Network in cellular backhaul is studied.
