Title:
MULTI-STATION POSITIONING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/125434
Kind Code:
A1
Abstract:
The present application provides a multi-station positioning method and a device, pertaining to the technical field of communications, and solving the problem of insufficient positioning accuracy resulting from RTT measurements in a positioning structure centered around a positioning management function. The method of the present application solves the above problem, and improves positioning accuracy by coordinating multiple base stations to perform RTT positioning. The method comprises: a target apparatus receiving positioning assistance information sent by a positioning center, the positioning assistance information comprising cell identifiers and reference signal configurations of a serving base station and at least one neighboring base station; the target apparatus performing, according to the positioning assistance information, a positioning measurement with respect to a downlink reference signal; the target apparatus sending, according to the positioning assistance information, an uplink reference to the serving base station and the at least one neighboring base station; and the target apparatus sending to the positioning center a downlink positioning measurement report comprising reference signal receiving and sending time differences corresponding to the serving base station and the at least one neighboring base station measured by the target apparatus.
