4G/Lte Channel Quality Reference Signal Traces Data Set

Mobile networks, especially LTE networks are used more and more for high-bandwidth services like multimedia or video streams. The quality of the data connection plays a major role in the perceived quality of a service. Videos may be presented in a low quality or experience a lot of stalling events when the connection is to slow to buffer the next frames for playback. So far, no publicly available data set exists that has a larger number of LTE network traces and can be used for deeper analysis. In this data set, we provide 546 traces of 5 minutes each with a sample rate of 100 ms. Thereof 377 traces are pure LTE data. We furthermore provide an Android app to gather further traces as well as R scripts to clean, sort, and analyze the data.移动网络，尤其是长期演进（LTE）网络，正日益广泛应用于多媒体、视频流等高带宽业务场景。数据连接的质量对用户感知的服务品质起着至关重要的作用。当连接速率过慢无法缓冲播放所需的下一帧时，视频可能出现画质低劣或频繁卡顿的情况。截至目前，尚未有公开可用的、包含大量LTE网络追踪数据且可用于深度分析的数据集。本数据集共提供546条时长为5分钟的网络追踪数据，采样率为100毫秒，其中377条为纯LTE网络追踪数据。此外，本数据集还提供一款用于采集更多网络追踪数据的安卓（Android）应用程序，以及用于数据清洗、排序与分析的R脚本。
