Abstract
A location management function (LMF) of a network provides timing errors to user equipment and/or base stations for positioning purposes. The LMF receives an indication of an effective timing error for a downlink time difference of arrival (DL-TDOA) positioning technique, wherein the effective timing error is associated with a set of base stations configured to transmit positioning reference signals for the DL-TDOA and provides the effective timing error to a user equipment (UE) performing operations related to the DL-TDOA.
