Title:
POSITIONING METHOD, APPARATUS AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/015610
Kind Code:
A1
Abstract:
The present application provides a positioning method, apparatus and device. The method comprises: receiving a first positioning reference signal (PRS) on a first frequency domain resource, wherein the first frequency domain resource is a frequency domain resource in an unlicensed frequency spectrum; receiving a second PRS on a second frequency domain resource, wherein the second frequency domain resource is a frequency domain resource in a licensed frequency spectrum; determining, according to the first PRS and the second PRS, a first positioning measurement result corresponding to the first PRS and a second positioning measurement result corresponding to the second PRS; and determining the position of a terminal according to the first positioning measurement result and the second positioning measurement result. The invention can be used to quickly and accurately determine the position of a terminal where a large number of frequency domain resources in a licensed frequency spectrum are not occupied.
