    • A method for fingerprinting positioning decision support comprises obtaining (210) a geographic distribution probability of positions of measurement. A first collection of simulated measurements according to a signal model is generated (212), wherein each simulated measurement is associated with a respective pixel. The signal model is based on base stations located in the area. Fingerprinting positioning reference data is computed (214) from the first collection and positions of the selected pixels. A second collection of simulated measurements is generated (216), which is statistically independent to the first collection. These simulated measurements are associated with a respective intended position within the area. Fingerprinting positioning is performed (218) by the second collection utilizing the computed fingerprinting positioning reference data. An estimated accuracy of the fingerprinting positioning is calculated (220) using a comparison between the intended position and the estimated position. This is made for evaluating positioning capabilities of fingerprinting positioning based on the measurement strategy.

    • A user equipment (36) herein resolves timing ambiguities associated with when the user equipment (360 is to perform assisted positioning measurements. The user equipment (36) receives assistance data that indicates positioning occasion periodicities of a first cell and a reference cell, and that indicates a positioning occasion timing offset between those cells. The user equipment (36) performs signal detection at candidate timing offsets surrounding the indicated positioning occasion timing offset, to determine which candidate timing offset has the greatest probability of being the actual positioning occasion timing offset between the first cell and the reference cell. The user equipment (36) may then time assisted positioning measurements for the first cell based on the candidate timing offset determined as most likely being the actual timing offset, rather than necessarily timing those measurements based on the offset indicated in the assistance data.

    • A network node (44) assists a user equipment (36) to perform positioning measurements on positioning signals (46) transmitted by one or more cells during respective positioning occasions of those cells. The node (44) selectively delays transmission of assistance data to the user equipment (36) as needed, based on defined uncertainty in one or more timing parameters, for the network node (44) to identify with certainty between which two consecutive positioning occasions of a reference cell the user equipment (36) will receive that assistance data. The node (44) correspondingly generates the assistance data to be transmitted to indicate positioning occasion timing for at least one cell relative to the latter of those two consecutive positioning occasions of the reference cell. Such calculation and transmission enables the user equipment (36) to be certain that the next reference cell positioning occasion occurring after its reception of the assistance data is the reference cell positioning occasion on which the assistance data is based.
