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.

Abstract: An apparatus, method and computer program is described comprising: receiving a first measurement report from a first communication node of a mobile communication system, wherein the first measurement report includes downlink measurement data generated at a user device in response to a positioning reference signal sent by the first communication node; receiving a second measurement report from the first communication node, wherein the second measurement report includes uplink measurement data generated at the first communication node in response to an uplink reference signal sent by the user device; determining an integrity of the measurement data based on a comparison of said uplink and downlink measurement data; and setting an integrity verification notification in accordance with the determined integrity.

Abstract: An apparatus, method and computer program is described. The method can include receiving a first measurement report from a first communication node of a mobile communication system. The first measurement report can include downlink measurement data generated at a user device in response to a positioning reference signal sent by the first communication node. The method can further include receiving a second measurement report from the first communication node. The second measurement report can include uplink measurement data generated at the first communication node in response to an uplink reference signal sent by the user device. The method can also include determining an integrity of the measurement data based on a comparison of said uplink and downlink measurement data and setting an integrity verification notification in accordance with the determined integrity.
