Abstract

A wireless device (12A) is configured to determine, for each of one or more links (14), one or more characteristics associated with wireless device positioning performance on the link. In some embodiments, the one or more characteristics include one or more of: geometric dilution of precision, GDOP, characteristics associated with the link; or line-of-sight, LOS, characteristics or non-LOS characteristics of the link. Regardless, the wireless device (12A) may also be configured to transmit control signaling (22) indicating the one or more characteristics determined for each of the one or more links (14). Based on this control signaling (22), a network node (16) may adapt positioning reference signal, PRS, configuration on at least one of the one or more links (14).
