Abstract
Techniques are provide for passive positioning of user equipment (UE) with analog beamforming. An example method for positioning a user equipment includes receiving a first positioning reference signal from a first base station at a first time, receiving a first timing difference value based on two or more positioning reference signals transmitted from the first base station, receiving a second positioning reference signal from a second base station at a second time, receiving a second timing difference value based on two or more positioning reference signals transmitted from the second base station, 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 first timing difference value and the second timing difference value.
