AI Technical Summary

Technical Problem

Conventional downlink positioning methods for user equipment (UE) fail to effectively determine intermediate information such as the angle of departure (AoD) or distance from an access network device, which is essential for accurate UE positioning.

Method used

The proposed method involves a network device receiving measurement information from the UE and using assistance information from the access network device to determine intermediate information like AoD or distance, enabling accurate UE positioning by exchanging information between serving and non-serving access network devices or between the UE and core network apparatuses.

Benefits of technology

This approach allows for the implementation of UE positioning even when the Location Management Function (LMF) apparatus cannot perform positioning based on measurement information alone, enhancing positioning accuracy and efficiency by utilizing AoD and distance information.

Abstract

This application provides a user equipment UE positioning method. A first base station receives first measurement information, where the first measurement information is obtained by user equipment UE by measuring a signal sent by the first base station. The first base station determines first intermediate information based on the first measurement information and first assistance information that is of the first base station, where the first intermediate information is used to determine position information of the UE. The first base station sends the first intermediate information to a first network device. When a position of the UE cannot be determined based on measurement information reported by the UE, positioning of the UE is implemented.
