摘要:
Method and arrangement in a first node for providing geographical position related information. The first node and a second node are comprised within a wireless communication system. The first node and the second node are adapted to exchange wireless signals. The method comprises receiving a signal from the second node. Apart of the received signal that has propagated through a first channel path from the second node is detected by using a circular correlator. A timing estimate associated with the propagation time of the part of the signal which is received over the first channel path from the second node is calculated. Thus the calculated timing estimate is provided, which timing estimate is to be used when determining the geographical position.
