There is provided a method for a user equipment. UE, of a wireless communication network, the method comprising: obtaining a first measurement data associated with a determined position of the UE and second measurement data, the first and second measurement data obtained by performing measurements by the UE; obtaining a difference value indicative of a difference between at least one measurement value of the first measurement data and at least one measurement value of the second measurement data; comparing the difference value with at least one repositioning threshold value provided by the wireless communication network to the UE; and if the difference value exceeds the at least one repositioning threshold value, triggering a transmission of a repositioning request to a network node of the wireless communication network.

Enhancing positioning efficiency

Various example embodiments relate to positioning of a target node. A positioning report may comprise positioning assistance measurements from the target node and at least one anchor node, wherein the positioning assistance measurements are associated with angular differences between a pair of uplink and/or downlink transmission and/or reception beam directions. Apparatuses, methods, and computer pro-grams are disclosed.

Spatial domain measurements for beam based positioning

Method comprising: ⋅selecting a subset of one or more beam pairs among a set of beam pairs via which a terminal and a base station are associated, wherein for each of the beam pairs of the subset, a suitability of the respective beam pair is better than a suitability threshold; for each of the beam pairs of the subset: ⋅⋅determining a respective set of at least two tones; ⋅⋅performing a respective relative phase measurement based on the respective virtual wavelength to obtain a respective virtual phase difference; and at least one of ⋅∘reporting the respective set of at least two tones and the respective virtual phase difference to the base station; and ⋅∘estimating a respective distance between the terminal and a transmission reception point of the base station emitting the respective beam pair based on the respective virtual phase difference and the preliminary uncertainty region.

Beam-based carrier phase positioning

Devices, methods and computer program products for beam ranking for positioning purposes are disclosed. A network node device transmits to a client device a beam ranking indication comprising beam specific first reference data and beam ranking criteria for positioning for downlink transmission beams between the network node device and the client device. In response to a received downlink transmission beam selection indication indicating a downlink transmission beam selected by the client device based on the transmitted beam ranking indication, the network node device transmits second reference data to the client device with at least one downlink transmission beam according to the received downlink transmission beam selection indication.
