Abstract: Methods and apparatuses provide a mechanism to account for timing errors of a wireless device in positioning measurements. In one example, a wireless device performs reference-signal transmissions or measurements and sends information to a network node that is involved in positioning of the wireless device. The information indicates associations of the reference-signal transmissions or measurements with respective timing groups of the wireless device. Each timing group represents a related set of transmission or reception timing errors within the wireless device. Based on the information, the network node accounts for the different timing-group associations when performing positioning calculations that are based on the reference-signal transmissions or measurements performed by the wireless device.
