    Abstract: Embodiments of the present invention disclose a method and an apparatus for positioning a user equipment. The method includes receiving positioning measurement information sent by a base station. The positioning configuration information includes a sum of a difference between receiving time and sending time on the UE and a difference between receiving time and sending time on the base station. A round trip time between the intermediate node that sends the CRS and the UE is calculated according to the positing in formation. A position of the UE is determined using position coordinates of the intermediate node that sends the CRS and the round trip time.
