Abstract: Systems, methods, apparatuses, and computer program products for dynamic antenna array angular phase deviation compensation for broad beam positioning. For example, certain embodiments may provide for multi-round trip time (multi-RTT) positioning where a user equipment (UE) may report time of departure (TOD) compensation values to a serving gNB and/or location management function (LMF). The LMF may calibrate the RTT computation with the received TOD compensation values. As another example, certain embodiments may provide for uplink time difference of arrival (UL-TDOA) positioning where an LMF may signal calculated assistance information to the UE to request time of departure TOD compensation values. The UE may report the TOD compensation values to a location management function (LMF), and the LMF may compensate initial relative time of arrival (RTOA) estimates using the TOD compensation values.

Abstract: Apparatus and methods for apparatus positioning are provided. Solution includes receiving (300) by an apparatus from a network element a signal having multipath propagated signal components and obtaining time domain samples of the multipath propagated signal components, mapping (302) the time domain samples to one or more frequency offset-delay pairs to obtain frequency offsets and delays of the received multipath propagated signal components, calculating (304) angle of arrival of one or more multipath propagated signal components, determining (306) the multipath propagated signal component corresponding to the direct propagation path between the apparatus and the network element, and controlling (308) the utilisation of the angle of arrival and delay of the multipath propagated signal component corresponding to the direct propagation path in the determination of the location of the apparatus.

Abstract: An arrangement for determining a location of a base station by user equipment uses measurements of reference signals of a base station from different user equipment positions. The measurement results are preprocessed and then provided to a machine learning entity. The machine learning entity estimates the location of the base station and provides the estimated location for use in other functionality of the user equipment.
