Transonic speed mobility support techniques for 6G-non terrestrial networks

초록

Non-Terrestrial Network (NTN) connectivity is expected to be used in sixth Generation (6G) telecommunication systems to support transonic speed mobility applications. NTN systems can provide wide-area coverage for applications that require high mobility. Third Generation Partnership Project (3GPP) is investigating a study on New Radio (NR) and solutions for NR to support NTN in Release-15 and Release-16 respectively. In this paper, we provide an overview of use cases, requirements and architecture of a non-terrestrial network and explain high mobility such as transonic speed mobility challenges and potential solutions to be resolved in 6G-NTN. In addition, we also describe the existing open research opportunities for non-terrestrial network implementation based on 5G-NR in order to encourage extensive research in 6G technology.
