摘要

在5G快速部署的推动下,我们对商用5G网络在野外的性能、功耗和应用体验质量(QoE)进行了深入的测量研究。我们研究了不同的5G运营商、部署方案(非独立、NSA与独立、SA)、无线电频段(毫米波和6ghz以下)、协议配置(例如:_无线电资源控制状态转换),移动模式(静止,步行,驾驶),客户端设备(即。_用户设备)和上层应用(文件下载、视频流、网页浏览)。我们的研究结果揭示了商用5G在上述不同场景下的吞吐量、延迟、切换行为、无线电状态转换和无线电功耗方面的关键特征,并与4G/LTE网络进行了详细比较。此外,我们的研究为上层应用如何通过平衡性能和能耗之间的关键权衡,以及考虑网络和计算资源的可用性,最好地利用5G提供了关键见解。我们已经在https://github.com/SIGCOMM21-5G/artifact上发布了我们研究的数据集和工具。

A variegated look at 5G in the wild: performance, power, and QoE implications
Motivated by the rapid deployment of 5G, we carry out an in-depth measurement study of the performance, power consumption, and application quality-of-experience (QoE) of commercial 5G networks in the wild. We examine different 5G carriers, deployment schemes (Non-Standalone, NSA vs. Standalone, SA), radio bands (mmWave and sub 6-GHz), protocol configurations (_e.g._ Radio Resource Control state transitions), mobility patterns (stationary, walking, driving), client devices (_i.e._ User Equipment), and upper-layer applications (file download, video streaming, and web browsing). Our findings reveal key characteristics of commercial 5G in terms of throughput, latency, handover behaviors, radio state transitions, and radio power consumption under the above diverse scenarios, with detailed comparisons to 4G/LTE networks. Furthermore, our study provides key insights into how upper-layer applications should best utilize 5G by balancing the critical tradeoff between performance and energy consumption, as well as by taking into account the availability of both network and computation resources. We have released the datasets and tools of our study at https://github.com/SIGCOMM21-5G/artifact.
