A method, performed by a wireless device (120), for reporting at least one measurement to a network node (130) is disclosed. The wireless device (120) determines (420) an extended format to be used for reporting, to the network node (130), at least one of: a code phase measurement, a carrier phase measurement or a GNSS Signal ID. The extended format extends at least one of: a range or a resolution, of an existing format for reporting the at least one of: the code phase measurement, the carrier phase measurement or the GNSS Signal ID. The wireless device (120) then sends (430) a measurement report comprising the at least one of: the code phase measurement, the carrier phase measurement or the GNSS Signal ID, to the network node (130), using the determined extended format. A method performed by the network node (130) is also described, whereby the network node (130) receives the measurement report.
