    Abstract: A technique for calibrating a positioning system comprising a plurality of anchor nodes used to determine tag positions within a localization area using radio technology is disclosed. A method implementation of the technique is performed using a measurement device comprising at least one odometry sensor and a localization tag configured to communicate with the plurality of anchor nodes using the radio technology. The method comprises performing (S202), at a plurality of first measurement points in the localization area using the localization tag, first ranging measurements with respect to the plurality of anchor nodes using the radio technology to determine respective first distances from the measurement device to the plurality of anchor nodes and performing, at the plurality of first measurement points using the at least one odometry sensor, first odometry measurements to estimate respective first positions of the measurement device in the localization area, estimating (S204) locations of the plurality of anchor nodes based on the respective first distances determined by the first ranging measurements and the respective first positions estimated by the first odometry measurements, and configuring (S206) the positioning system with the estimated locations of the plurality of anchor nodes to calibrate the positioning system.

    Abstract: A method in a first radio network node (115) for handling position measurements is provided. The first radio network node (115) receives from a second radio network node (105, 110) a position measurement associated with a user equipment (110), and a system frame number. The system frame number is associated with the second radio network node (105, 110). The system frame number is further related to a point in time when the position measurement was performed. The first radio network node (115) calculates a position estimate of the position of the user equipment (110) based on the position measurement. The first radio network node (115) defines a time stamp which is based on the received system frame number. The first radio network node (115) then signals to a third radio network node (120) a positioning response. The positioning response comprises the position estimate and the time stamp.

    Abstract: The present invention relates to a method, mobile station and base station in a soft handover cellular communications system. A problem addressed is the complexity imposed by a soft handover combination node in the network for combining packets received from one mobile station over parallel diversity links. The combination node is a problem with respect to the network complexity, transmission capacity and retransmission delays. The present invention solves the problem by selecting on a packet-by-packet basis one of an active set base stations for forwarding the packet further uplink. Thereby no combination node in the network is needed. The mobile stations select the base station after transmitting a packet or prior to transmitting it. The selection is based on measures of the radio link qualities made during transmission of the relevant packet or made prior to its transmission.

    Abstract: A technique for predicting radio quality in a wireless communication network depending on assumed positions of one or more base stations in an area to be covered by the wireless communication network is disclosed. A method implementation of the technique is performed by a computing unit and comprises the steps of (a) determining (S202), for a selected position in the area with respect to assumed positions of the one or more base stations, blocking object features indicative of a spatial pattern of blocking objects present in fields of view between the selected position and the assumed positions of the one or more base stations, and (b) determining (S204), based on the determined blocking object features, a predicted radio quality at the selected position using a machine learning model trained to map blocking object features for selected positions with respect to one or more base station positions to corresponding radio qualities at the selected positions.

    Abstract: The invention provides a method by which a network element in a telecommunications network can report factors that have limited the performance of a UE in an observation period. A bottleneck score is calculated for each factor, the bottleneck score providing a measurement of the extent to which that factor has limited the performance of that UE compared to other factors in the observation period A data record for the UE is populated with the bottleneck scores and sent in a report towards upper layer management functions. When these reports are received (e.g. by a MME) they may be complemented with global entities of the users and aggregated measures created. The bottleneck scores may be calculated by collecting per-UE performance counters from a radio scheduler and estimating an actual UE performance from the collected performance counters, replacing one or more of the measured performance counters with a hypothetical value reflecting a particular factor operating ideally, and estimating a theoretical user performance based on the hypothetical value and remaining performance counters, and assigning a bottleneck score for that factor by comparing the estimated actual user performance with the estimated theoretical user performance.

    Abstract: A system and method of communicating between nodes in an ad hoc polling based communication infrastructure such as a Bluetooth system. Frames on a link between two nodes are designated as checkpoint frames on which each of the two nodes checks for presence of the other. Based upon factors such as attendance or absence of the checkpoint frames and usage of the link, one or the other node can adjust the node checking intensity and the other node follows suit in accordance with predefined rules. The checkpoint frames can either be periodic or pseudo random.
