US 11,109,193 B2 · Method and device for performing positioning using drone

Abstract

An embodiment of the present specification may provide a method for performing positioning using a drone by a terminal in a wireless communication system. The method for performing positioning using a drone by a terminal may comprise the steps of: transmitting information on a drone-positioning reference signal (D-PRS) configuration to a base station; receiving the D-PRS configuration information from the base station; receiving a positioning reference signal (PRS) from the base station and receiving the D-PRS from the drone; obtaining position-related information of the terminal on the basis of the PRS and the D-PRS; and transmitting the position-related information to the base station. The terminal is capable of communicating with at least one of another terminal, a terminal related to an autonomous driving vehicle, a base station or a network.

Dependent claims

A method of performing positioning using a drone by a user equipment (UE) in a wireless communication system, the method comprising:

transmitting information for receiving a drone positioning reference signal (D-PRS) configuration to a base station (BS);
receiving the D-PRS configuration information from the BS, based on the information transmitted by the UE, wherein the D-PRS configuration is based on information required for synchronization of a transmission timing of a D-PRS with a transmission timing of a PRS that is exchanged between the BS and the drone;
receiving a positioning reference signal (PRS) from the BS and receiving a D-PRS from a drone, wherein the PRS and D-PRS are synchronized with each other, according to the synchronized transmission timing;
obtaining location-related information about the UE based on the PRS and the D-PRS;
and
transmitting the location-related information to the BS.

A user equipment (UE) for performing positioning using a drone in a wireless communication system, the UE comprising:

a receiver configured to receive a signal;
a transmitter configured to transmit a signal;
and
a processor configured to control the receiver and the transmitter,
wherein the processor is further configured to:
control the transmitter to transmit information for receiving a drone positioning reference signal (D-PRS) configuration to a base station (BS),
control the receiver to receive the D-PRS configuration information from the BS, based on the transmitted information, wherein the D-PRS configuration is based on information required for synchronization of a transmission timing of a D-PRS with a transmission timing of a PRS,
control the receiver to receive a positioning reference signal (PRS) from the BS and receive a D-PRS from the drone, wherein the PRS and D-PRS are synchronized with each other, according to the synchronized transmission timing,
obtain location-related information about the UE based on the PRS and the D-PRS, and
control the transmitter to transmit the location-related information to the BS.
