Embodiment Construction

[0068] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present application.

[0069] figure 1 is a schematic diagram of a scenario of user equipment downlink positioning. exist figure 1 In the scenario shown in , since the distances from different base stations to the UE may be the same or different, the times at which signals propagate from different base stations to the UE may also be the same or different. According to the arrival time of the signals sent by the base station 110, the base station 120, and the base station 130 at ...

Abstract

The application provides a user equipment UE positioning method, the user equipment UE sends a plurality of pieces of first measurement information to a first network device, the plurality of pieces of first measurement information being obtained by the UE measuring a signal sent by at least one first access network device. The multiple pieces of first measurement information and the first auxiliary information are used for the first network equipment to determine first intermediate information, the first auxiliary information is sent to the first network equipment by the first access network equipment, and the first auxiliary information comprises multiple pieces of beam direction information. According to the method provided by the invention, the positioning of the UE is realized under the condition that the position of the UE cannot be determined through the measurement information reported by the UE.

Description

[0001] This application is a divisional application of an invention application with a filing date of March 15, 2019, a Chinese application number of 201910199679.4, and an application title of "Apparatus and Method for Positioning User Equipment". technical field [0002] The present application relates to data transmission, and in particular to a user equipment positioning device and method. Background technique [0003] In the traditional downlink positioning method, the user equipment (user equipment, UE) measures the arrival time of multiple cell base station downlink signals to the UE and the arrival time difference (time difference of arrival) of the reference base station downlink signal to the user equipment (user equipment, UE). , TDOA) and other measurement information, and send the measurement information to a location management function (location management function, LMF) device. The LMF device can determine the location of the UE according to the measurement i...
