In this paper, we discuss the temporal behavior of several key parameter indicators (KPIs) in LTE downlink (DL) based on multiple long-term static measurement campaigns conducted under various conditions, including rural and urban indoor and outdoor scenarios. We publish part of the measurements as an open dataset. We conclude that the reference signal received power (RSRP) does not show any time-of-day patterns and thus can be modeled as time-invariant for limited periods of time (from several hours to multiple days) followed by occasional anomalies in the form of jumps of several dB. The other KPIs, for example, throughput, exhibit repeated diurnal patterns with significant differences between peak hours (full cell in the afternoon and evening) and off-peak hours (empty cell in the early morning). Even under model idealizations, such KPIs should be thus modeled at least as cyclostationary random processes. We are not aware of any other paper that would provide static LTE DL measurement data covering several weeks and would thus allow the scientific community to study the diurnal patterns without a need to perform own measurements.
