He is a technology pre-research engineer at the Algorithm Department, ZTE Corporation. His research focuses on next generation radio access network.|GAO Yin received the master degree in circuit and system from Xidian University, China in 2005. Since 2005, she has been with the research center of ZTE Corporation and is engaged in the study of 4G/5G technology. She has authored about hundreds of proposals for 3GPP meetings and journal papers in wireless communications. From June 2021, she has been elected as the 3GPP RAN3 Chairman.


In the new radio (NR) access technology, non-terrestrial networks (NTN) are introduced to meet the requirement of anywhere and anytime connections from the world market. With the introduction of NTN, the NR system is able to offer the wide-area coverage and ensure the service availability for users. In this paper, the general aspects of NTN are introduced, including the NTN architecture overview, the impact of NTN on next-generation radio access network (NG-RAN) interface functions, mobility scenarios and other NTN related issues. The current progress in 3GPP Release 17 is also provided.
