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.

Abstract: A solution for reliable communication in an apparatus of a communication system is provided. The solution comprises receiving (302) from a network element data packets to be transmitted to a user terminal; maintaining (304) one or more transmit buffers for transmitting data packets to the user terminal; transmitting (306) data packets to a user terminal; receiving (308) information from the user terminal regarding whether one or more data packets are successfully or not successfully received; transmitting (310) on the basis of received information acknowledgement information to another network element of the communication system; receiving (312) a notification that one or more packets have been successfully transmitted to the user terminal from a second corresponding apparatus; and, if the one or more transmit buffers comprise the successfully transmitted packets, removing (314) the packets from the buffers.

Abstract: Disclosed is a method comprising initiating, by an apparatus, an activation procedure for activating one or more positioning reference units for a positioning session of the apparatus; wherein the activation procedure is initiated via a small data transmission based on at least one of: a number of detected network nodes being above a first threshold value, or a number of detected positioning reference units being above a second threshold value; or wherein the activation procedure is initiated by transmitting an activation request to the one or more positioning reference units over sidelink based on the number of detected positioning reference units comprising at least the one or more positioning reference units.

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: Disclosed is a method comprising obtaining a first set of measurement information associated with a reference signal transmitted from a set of positioning reference units; selecting a subset of positioning reference units from the set of positioning reference units, wherein the selection is based at least on determining that the reference signal transmitted per positioning reference unit of the subset of positioning reference units is measured by a same set of network nodes that measured a reference signal transmitted from a target user device; and refining a location estimate of the target user device based at least on a subset of measurement information from the first set of measurement information, wherein the subset of measurement information is associated with the subset of positioning reference units.

Abstract: A positioning reports producer (101) comprising: —means for receiving one or more reference signals for positioning a target end device; —means for receiving a set of trained parameters defining a training-based compression algorithm, the set of trained parameters being obtained by a joint training of the training-based compression algorithm and one or more training-based algorithms implemented in a positioning reports consumer (102); —means for generating a compressed positioning report by running the training-based compression algorithm; and —means for sending the compressed positioning report to the positioning reports consumer (102).
