Title:
NETWORK-BASED POSITIONING METHOD USING RELAY IN NR-V2X SYSTEM, AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/059876
Kind Code:
A1
Abstract:
The present invention relates to a method for performing positioning in a new radio-vehicle to everything (NR-V2X) system, and a device therefor. A method for performing network-based positioning in a new radio-vehicle to everything (NR-V2X) communication system according to an aspect may comprise the steps of: determining whether positioning using a relay is required, on the basis of whether there is performance deterioration in positioning of a terminal; determining at least one relay terminal to be used as an anchor node for positioning of the terminal when the positioning using the relay is required; requesting terminal assistant measurement information for the positioning of the terminal from the relay terminal; receiving the terminal assistant measurement information from the relay terminal; and measuring an absolute position of the terminal on the basis of the terminal assistant measurement information, wherein the terminal requiring the positioning using the relay is classified as a remote terminal, and the terminal assistant measurement information includes relay terminal assistant measurement information for performing positioning of the relay terminal and remote terminal assistant measurement information for performing positioning of the remote terminal.
