Abstract
A method performed by a receiving radio node for positioning a radio device is provided. The receiving radio node receives a first signal from a transmitting radio node, and measures a time of arrival of the first signal. The first signal is also received by a radio device. The receiving radio node further receives a second signal from the radio device. The second signal is the first signal that has been scattered and frequency modulated by the radio device when the first signal was received by the radio device. The receiving radio node measures a time of arrival of the second signal. The receiving radio node then calculates a Time Difference Of Arrival (TDOA) based on the measured time of arrival of the first signal and the measured time of arrival of the second signal.
