论文摘要
在本文中，我们评估了IEEE 802.11AX的参数空间重复使用（PSR）框架的性能，主要关注其对传输潜伏期的影响。基于详细的标准系统级模拟，我们对PSR的影响进行了现实分析，以考虑不同方案密度，交通负载和访问点（APS）天线功能，以量化各种情况下的性能提高。我们的结果表明，在中等密度的情况下，相对于没有PSR的802.11ax系统，PSR可提供5％最差的延迟时间的3.8倍降低。此外，我们的研究表明，对于低延迟通信，提供PSR功能的网络可能是部署更昂贵的多人APS AP的一种有吸引力的替代方法。
In this article, we evaluate the performance of the parameterized spatial reuse (PSR) framework of IEEE 802.11ax, mainly focusing on its impact on transmission latency. Based on detailed standard-compliant system-level simulations, we provide a realistic analysis of the effects of PSR considering different scenario densities, traffic loads, and access points (APs) antenna capabilities to quantify its performance gains under various scenarios. Our results show that, in medium-density scenarios, PSR can offer up to a 3.8x reduction in the 5% worst-case latencies for delay-sensitive stations with respect to an 802.11ax system without PSR. Moreover, our study demonstrates that, for low-latency communications, providing the network with PSR capabilities may be an appealing alternative to the deployment of more costly multi-antenna APs.
