Abstract
User Equipment (UE), computer readable medium, and method to determine a mobility of the UE are disclosed. The UE may include circuitry configured to determine a plurality of signals from a serving cell. The each signal of the plurality of signals may be one or more of: a reference signal receive power (RSRP), a reference signal receive quality (RSRQ), a received signal strength indicator (RSSI), a signal-to-noise ratio (SNR), a signal-to-interference-ratio (SIR), a signal-to-interference-plus-noise ratio (SINR), and a CQI. The circuitry may be configured to determine a measure for each of a window size of the plurality of signals. Each measure may be a variance of the plurality of signals, a standard deviation of the plurality of signals, a percent confidence interval (CI) of a mean of the measure, and a linear combination of measures. The circuitry may determine whether the UE is stationary based on one or more measures.
