1. A method for positioning a user equipment (UE), the method comprising:
receiving positioning measurement information sent by a base station, wherein the positioning measurement information comprises 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, coordinates of an intermediate node when the base station sends a signal to the UE through the intermediate node, a device index number of the intermediate node, and a time interval between a time when the base station sends a signal to the intermediate node and a time when the intermediate node sends a signal to the UE, wherein the difference between the receiving time and the sending time on the UE is a time difference between a time when the UE sends an uplink reference signal and a time when the UE receives a cell reference signal (CRS) and the difference between the receiving time and the sending time on the base station is a time difference between a time when the base station receives the uplink reference signal and a time when the base station sends the CRS, wherein the CRS comprises a CRS sent by the base station to the UE and/or a CRS sent by the base station to the UE through the intermediate node; calculating, according to the positioning measurement information, a round trip time between the intermediate node that sends the CRS and the UE; and determining, a position of the UE using position coordinates of the intermediate node that sends the CRS and the round trip time.
