Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) may obtain a first set of position estimates of the UE based on applying a first positioning model to one or more radio frequency fingerprint positioning (RFFP) measurements. The UE may obtain a second set of position estimates of the UE using a positioning technique that does not use the first positioning model. The UE may transmit a mismatch report, wherein the mismatch report is based on comparing the first set of position estimates with the second set of position estimates.

A method for determining a position of an object includes determining a first estimated location of the object based on a distance matrix, a range matrix, and a weight matrix, updating the weight matrix based on distance related factors and ranging technique related factors, and determining a second estimated location based on the distance matrix, the range matrix, and the updated weight matrix. The distance matrix includes distances between the object and one or more anchors and the range matrix includes ranging measurements for ranging communications between the object and the one or more anchors.
