60 GHz频段NR-U和WiGig共存
NR-U and WiGig Coexistence in 60 GHz Bands
摘要：
2019年12月，3GPP定义了Release-17的路线图，其中包括在具有高度定向通信系统的毫米波段中运行新无线电（NR）的新功能，即，高达52.6 GHz。本文对基于NR的非授权频谱接入（NR-U）和IEEE技术（即，802.11ad无线千兆（WiGig），在60 GHz频段进行。对于NR-U，使用基于NR Release-15的模型的扩展，使得满足60 GHz监管要求。首先，开发的开源的ns-3为基础的模拟器的设计和能力，然后端到端的性能结果的共存与不同的信道接入机制NR-U在3GPP室内场景进行了讨论。结果表明，具有先听后说信道接入机制的NR-U在吞吐量和延迟方面对WiGig性能没有任何不利影响，这表明NR-U设计满足公平共存目标，即，NR-U和WiGig共存被证明是可行的。
英文摘要：
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.
