论文摘要
2019年12月，3GPP定义了Release-17的路线图，其中包括具有高方向通信系统的新广播（NR）运行（NR）的新功能，即高达52.6 GHz。在本文中，进行了基于系统级模拟的研究，基于基于NR的访问无执照的频谱（NR-U）和IEEE技术的共存，即在60 GHz频段进行的802.11AD Wireless Gigabit（Wigig）。对于NR-U，使用基于NR Releaser-15的模型的扩展，以便满足60 GHz的调节要求。首先，提出了开发的开源NS-3模拟器的设计和功能，然后在3GPP室内方案中讨论了与NR-U的不同通道访问机制共存的端到端性能结果。结果表明，具有听 - 与通信通道访问机制的NR-U对Wigig性能没有任何不利影响，这表明NR-U设计实现了公平的共存目标，即NR-U和Wigig并存是可行的。
In December 2019, the 3GPP defined the road-map for Release-17, which includes new features on the operation of New Radio (NR) in millimeter-wave bands with highly directional communications systems, i.e., up to 52.6 GHz. In this paper, a system-level simulation based study on the coexistence of NR-based access to unlicensed spectrum (NR-U) and an IEEE technology, i.e., 802.11ad Wireless Gigabit (WiGig), at 60 GHz bands is conducted. For NR-U, an extension of NR Release-15 based model is used such that the 60 GHz regulatory requirements are satisfied. First, the design and capabilities of the developed open source ns-3 based simulator are presented and then end-to-end performance results of coexistence with different channel access mechanisms for NR-U in a 3GPP indoor scenario are discussed. It is shown that NR-U with Listen-Before-Talk channel access mechanism does not have any adverse impact on WiGig performance in terms of throughput and latency, which demonstrates that NR-U design fulfills the fairness coexistence objective, i.e., NR-U and WiGig coexistence is proven to be feasible.
