Abstract: The apparatus may be a UE. The UE may be configured to measure, over a time interval, a plurality of instances of a signal received from a serving device (e.g., a base station or serving UE). The UE may further be configured to adjust, based on at least two previously measured instances of the signal, a sampling rate associated with the signal received from the serving device. The UE may further be configured to maintain a particular number (e.g., 2-10) of previously measured instances of the signal, where adjusting the sampling rate is based on the maintained particular number of previously measured instances. The particular number of previously measured instances of the signal may be used to calculate a gradient of the measurements to identify a sampling rate associated with the calculated gradient.
