Abstract: An apparatus is disclosed, the apparatus comprising means for estimating a first angle (θ1) between a first path between a first base station and at least one target node and a second path between the first base station and a second base station, and estimating a second angle (θ2) between a third path between the second base station and the at least one target node and the second path. The apparatus also comprises means for determining a value (Δd) indicative of a difference between a first distance between the at least one target node and the first base station and a second distance between the at least one target node and the second base station, wherein determining the value is based on the estimated first and second angles (θ1) (θ2) and a known distance (l) between the first and second base stations.
