Abstract: The embodiments of the present invention provide a user equipment positioning method, apparatus, a base station and a storage medium, and relates to the technical field of wireless communication. The method is applied to a base station and comprises: receiving a pilot signal sent by a target UE; calculating a CSI estimation value of a channel between the base station and the target UE according to the received pilot signal; calculating transmission directions of the pilot signal along different signal paths according to the CSI estimation value to obtain AoA estimation values; performing directional beamforming based on the AoA estimation values to generate a spatially filtered CSI estimation value; performing Kalman filtering on the spatially filtered CSI estimation value to generate an enhanced CSI estimation value; calculating transmission distances of the pilot signal transmitted along different signal path according to the enhanced CSI estimation value to obtain distance estimation values; determining a position of the target UE according to a minimum distance estimation value among the distance estimation values and an AoA estimation value corresponding to the minimum distance estimation value. The solutions provided by the embodiments of the present invention can improve the accuracy of UE positioning.
