Title:
TERMINAL DEVICE POSITIONING METHOD, DEVICE AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/134563
Kind Code:
A1
Abstract:
Disclosed in the embodiments of the present application are a terminal device positioning method, device and system, the method comprises: obtaining positioning measurement data for a terminal device to be positioned by means of a measurement function entity at a terminal side and/or a measurement function entity at an access side, wherein the positioning measurement data comprises a channel estimation and/or a channel impulse response obtained according to a corresponding downlink/uplink reference signal. The measurement function entity at the terminal side and/or the measurement function entity at the access side report the positioning measurement data to a positioning function entity in a network, so that the positioning function entity may estimate the position of the terminal device on the basis of the positioning measurement data so as position the terminal device, which improves the accuracy of positioning. The described technical solution may be applied so as to position a terminal device in a single base station or multiple base station-based positioning environment.
