Abstract

Methods and apparatuses provide a mechanism to account for timing errors of a wireless device (12) in positioning measurements. In one example, a wireless device (12) performs reference-signal transmissions or measurements and sends information to a network node (20) that is involved in positioning of the wireless device (12). The information indicates associations of the reference-signal transmissions or measurements with respective timing groups of the wireless device (12). Each timing group represents a related set of transmission or reception timing errors within the wireless device (12). Based on the information, the network node (20) 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 (12).
