随着新的5G NR标准的规范在3GPP内部进行，从最近批准的3GPP规范中提取见解，提供通用的、全栈的、端到端(E2E)和开源的模拟器变得必要。本文提出了对著名的离散事件网络模拟器ns-3的扩展，以支持NR无线接入网。本文描述了MAC层和物理层的设计和实现选择，并讨论了管理不同带宽部分的技术解决方案。最后，我们根据3GPP流程给出了校准结果，并展示了如何在实际部署场景中获得E2E性能指标，特别是E2E时延。
As the specification of the new 5G NR standard proceeds inside 3GPP, the availability of a versatile, full-stack, End-To-End (E2E), and open source simulator becomes a necessity to extract insights from the recently approved 3GPP specifications. This paper presents an extension to ns-3, a well-known discrete-event network simulator, to support the NR Radio Access Network. The present work describes the design and implementation choices at the MAC and PHY layers, and it discusses a technical solution for managing different bandwidth parts. Finally, we present calibration results, according to 3GPP procedures, and we show how to get E2E performance indicators in a realistic deployment scenario, with special emphasis on the E2E latency.
