Abstract: A position estimation device for estimating the position of an initiator communication device comprises data obtaining circuitry configured to obtain path data of two or more paths of RF signals transmitted by a responder communication device, wherein RF signals of at least one path are reflected at a scatterer, said path data comprising, per path of an RF signal: path length information indicating the length of the propagation path of an RF signal from the responder communication device via a scatterer to the initiator communication device, angle of departure information indicating the angle of departure of an RF signal from the responder communication device, and angle of arrival information indicating the angle of arrival of an RF signal at the initiator communication device. The device further comprises processing circuitry configured to determine the position of the initiator communication device on the basis of the obtained path data.
