Document Type and Number:
WIPO Patent Application WO/2022/116857
Kind Code:
A1
Abstract:
The present application provides a positioning method and apparatus, an electronic device and a computer readable storage medium. The positioning method comprises: receiving a positioning measurement value sent by a positioning reference information receiver in a communication system, the positioning reference information receiver being a user equipment (UE) to be positioned or at least two base stations; obtaining a three-dimensional measurement distance between each base station and said UE on the basis of the positioning measurement value; and obtaining horizontal coordinates of said UE on the basis of each three-dimensional measurement distance, the three-dimensional coordinates of each base station and the height of said UE. According to the solution, the three-dimensional measurement distances between a plurality of base stations and said UE are obtained, and the horizontal coordinates of said UE are obtained on the basis of the plurality of three-dimensional measurement distances, the three-dimensional coordinates of the plurality of base stations and the height of said UE. Because of the addition of known information, i.e., the height of said UE, the solution improves the precision of two-dimensional positioning on the premise of ensuring the positioning performance compared with the prior art.
