Patent ID: 8744481

Claim:
A method in a first node, for providing geographical position related information, the first node and a second node are comprised within a wireless communication system and adapted to exchange wireless signals, the method comprises the steps of: receiving a signal from the second node, detecting, by using a circular correlator, a part of the received signal that has propagated through a channel path from the second node, calculating a timing estimate associated with the propagation time of the part of the signal which is received through the channel path from the second node, providing the calculated timing estimate for use when determining the geographical position related information, wherein the first and second nodes comprise a base station and a user equipment, respectively, or comprise the user equipment and the base station, respectively, receiving radio fingerprint measurement data from the user equipment at the base station after providing the calculated timing estimate, and after receiving the radio fingerprint measurement data from the user equipment, transmitting the geographical position related information from the base station to the user equipment, wherein the geographical position related information is based on the radio fingerprint measurement data and is indicative of a geographic position of the user equipment.
