Abstract

The embodiment of the invention discloses a method, a device and a system for positioning user equipment. The method for positioning the user equipment provided by the embodiment of the invention comprises the following steps of: receiving a positioning signal which is sent by the user equipment and carries a ZC sequence or a CG sequence; and determining the position of the user equipment according to the positioning signal. By adopting the method, the device and the system, a frequency division multiple access (FDMA) system under long-term evolution architecture can accurately determine the position of the user equipment through a network. The embodiment of the invention also discloses a method for measuring arrival time, a method for sending the positioning signal, a base station and the user equipment.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a positioning technology of user equipment. Background technique [0002] At present, the network-based positioning technology is mainly applied in TDMA (Time division multiple access, time division multiple access) and WCDMA (Wide band Code Division Multiple Access, wideband code division multiple access) systems. The U-TDOA (Uplink Time Difference of Arrival, Uplink Time Difference of Arrival) positioning algorithm of the network-based positioning technology is as follows: the base station calculates the position of the UE by using the positioning signal sent by the user equipment UE. The specific positioning process is as follows: assuming that the number of base stations receiving UE positioning signals is four (including the serving base station), the four base stations simultaneously detect the positioning signals transmitted by the UE, and perform acc...
