摘要

In the new radio (NR) access technology, non-terrestrial networks (NTN) are intro?duced 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 en?sure the service availability for users. In this paper, the general aspects of NTN are intro?duced, 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 is?sues. The current progress in 3GPP Release 17 is also provided.
