Abstract
Techniques are provide for calibrating device timelines for use in passive positioning of user equipment (UE). An example method for passive positioning of a user equipment includes receiving a first positioning reference signal from a first device at a first time, receiving a second positioning reference signal from a second device at a second time, receiving a timeline difference value associated with the first device and the second device, and determining a time difference of arrival between the first positioning reference signal and the second positioning reference signal based at least in part on the timeline difference value.
