Abstract
A network node such as a positioning node, and a related method of determining an uncertainty of a timing measurement used for positioning of a wireless device are disclosed. The method includes estimating a timing measurement uncertainty, and determining if an uncertainty reducing measurement is available. If an uncertainty reducing measurement is available, the method also comprises determining a timing measurement uncertainty based on the estimated timing measurement uncertainty and the uncertainty reducing measurement.
