摘要

在版本17中，3GPP引入了对5G新无线电（NR）规范的适应和增强，以支持非地面网络（NTN）操作。主要挑战是传播延迟时间长，特别是在地球同步轨道部署中，以及低地球轨道部署中卫星的移动。在本文中，我们概述了支持NTN的协议调整。主要的用户平面协议适配包括由于长传播延迟而对随机接入和混合自动重复请求的改变。控制平面协议适配包括用于用户设备的各种与移动性相关的增强。

Radio interface protocols and radio resource management procedures for 5G new radio non-terrestrial networks

In Release 17, 3GPP introduced adaptations and enhancements to the 5G new radio (NR) specification to support non-terrestrial networks (NTNs) operation. The main challenges were due to long propagation delays, especially in GEO deployments, and the movement of the satellites in LEO deployments. In this paper, we give an overview of the protocol adaptations to support NTNs. The main user plane protocol adaptations include changes to random access and hybrid automatic repeat request to due long propagation delays. The control plane protocol adaptations include a variety of mobility related enhancements for user equipment.
