Abstract

The present disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate than a 4G communication system such as LTE. The present disclosure relates to a method for a report on flight path and measurement information of an aerial UE in a wireless communication system, the method comprising the steps of: transmitting, to a base station, an RRC message including flight path information; on the basis of the RRC message, transmitting, to the base station, UE capability information related to a report function of the flight path information; on the basis of the UE capability information, receiving, from the base station, a report request message of the flight path information; and transmitting, to the base station, a response message to the report request message of the flight path information.

First claim

1 . A method performed by a terminal in a wireless communication system, the method comprising:
transmitting, to a base station, terminal capability information comprising information on whether path reporting of the terminal is supported; receiving, from the base station, configuration information regarding the path reporting, based on the terminal capability information; and transmitting path information of the terminal to the base station, based on the configuration information, wherein the path information comprises velocity information at at least one location on a path of the terminal, and wherein a threshold time related to a signal strength of a target cell for a handover of the terminal is based on the velocity information.

2 . The method of claim 1 , wherein the information on whether the path reporting is supported comprises at least one of information on whether reporting of the velocity information is supported or information on a velocity format reportable by the terminal.

3 . The method of claim 1 ,
wherein the configuration information comprises at least one of the number of times the path reporting is performed or a request for the velocity information, and wherein the velocity information comprises at least one of information on horizontal velocity, information on vertical velocity, or information on velocity uncertainty.

4 . The method of claim 1 ,
wherein the terminal is an unmanned aerial vehicle terminal, and wherein the path information is flight path information of the unmanned aerial vehicle terminal.

5 . A method performed by a base station in a wireless communication system, the method comprising:
receiving, from a terminal, terminal capability information comprising information on whether path reporting of the terminal is supported; transmitting, to the terminal, configuration information regarding the path reporting, based on the terminal capability information; and receiving path information of the terminal from the terminal, based on the configuration information, wherein the path information comprises velocity information at at least one location on a path of the terminal, and wherein a threshold time related to a signal strength of a target cell for a handover of the terminal is based on the velocity information.

6 . The method of claim 5 , wherein the information on whether the path reporting is supported comprises at least one of information on whether reporting of the velocity information is supported or information on a velocity format reportable by the terminal.

7 . The method of claim 5 ,
wherein the configuration information comprises at least one of the number of times the path reporting is performed or a request for the velocity information, and wherein the velocity information comprises at least one of information on horizontal velocity, information on vertical velocity, or information on velocity uncertainty.

8 . The method of claim 5 ,
wherein the terminal is an unmanned aerial vehicle terminal, and wherein the path information is flight path information of the unmanned aerial vehicle terminal.

9 . A terminal in a wireless communication system, the terminal comprising:
a transceiver; and at least one controller connected to the transceiver, wherein the at least one controller is configured to:
transmit, to a base station, terminal capability information comprising information on whether path reporting of the terminal is supported,
receive, from the base station, configuration information regarding the path reporting, based on the terminal capability information, and
transmit path information of the terminal to the base station, based on the configuration information,
wherein the path information comprises velocity information at at least one location on a path of the terminal, and wherein a threshold time related to a signal strength of a target cell for a handover of the terminal is based on the velocity information.

10 . The terminal of claim 9 , wherein the information on whether the path reporting is supported comprises at least one of information on whether reporting of the velocity information is supported or information on a velocity format reportable by the terminal.

11 . The terminal of claim 9 ,
wherein the configuration information comprises at least one of the number of times the path reporting is performed or a request for the velocity information, and wherein the velocity information comprises at least one of information on horizontal velocity, information on vertical velocity, or information on velocity uncertainty.

12 . The terminal of claim 9 ,
wherein the terminal is an unmanned aerial vehicle terminal, and wherein the path information is flight path information of the unmanned aerial vehicle terminal.

13 . A base station in a wireless communication system, the base station comprising:
a transceiver; and at least one controller connected to the transceiver, wherein the at least one controller is configured to:
receive, from a terminal, terminal capability information comprising information on whether path reporting of the terminal is supported,
transmit, to the terminal, configuration information regarding the path reporting, based on the terminal capability information, and
receive path information of the terminal from the terminal, based on the configuration information,
wherein the path information comprises velocity information at at least one location on a path of the terminal, and wherein a threshold time related to a signal strength of a target cell for a handover of the terminal is based on the velocity information.

14 . The base station of claim 5 , wherein the information on whether the path reporting is supported comprises at least one of information on whether reporting of the velocity information is supported or information on a velocity format reportable by the terminal.

15 . The base station of claim 5 ,
