Abstract

A first electronic device according to various embodiments of the present disclosure may: determine a location of the first electronic device via an out of band (OOB) connection; select, on the basis of information regarding the determined location, an applet within the first electronic device; and carry out, by using the selected applet, ultra-wideband (UWB) communication with a second electronic device adjacent to the determined location.

First claim

The invention claimed is:

1. A method of a first electronic device for performing ultra-wideband (UWB) communication, the method comprising:
determining a location of the first electronic device via an out-of-band (OOB) connection;
selecting an applet in the first electronic device, based on information on the determined location; and
performing UWB communication with a second electronic device adjacent to the determined location by using the selected applet,
wherein the performing of UWB communication with the second electronic device comprises:
requesting slot allocation for the UWB communication to the second electronic device,
in response to the request, receiving allocation of a slot for the UWB communication from the second electronic device, and
performing the UWB communication in the allocated slot.

2. The method of claim 1 , wherein the determining of the location of the first electronic device via the OOB connection comprises:
receiving a Bluetooth advertisement message; and
determining the location of the first electronic device, based on location information included in the received Bluetooth advertisement message.

3. The method of claim 2 , wherein the first electronic device is a mobile device, the second device is a gate within a station, and the location information included in the received Bluetooth advertisement message comprises identifier (ID) information of the station.

4. The method of claim 1 , wherein the information on the determined location is acquired from an application included in the first electronic device, based on the determined location.

5. The method of claim 4 , wherein the information on the determined location comprises at least one of identifier (ID) information of the second electronic device, address information of the second electronic device, condition information for accessing the second electronic device, condition information for selecting the applet, information of a UWB anchor adjacent to the determined location, and UWB block structure information.

6. The method of claim 5 ,
wherein the condition information for accessing the second electronic device comprises condition information related to a distance between the first electronic device and the second electronic device, and
wherein the distance between the first electronic device and the second electronic device is estimated based on at least one of downlink-time difference of arrival (DL-TDoA), a global positioning system (GPS), and a receiver signal strength indicator (RSSI).

7. A first electronic device comprising:
a first communication unit configured to perform ultra-wideband (UWB) communication;
a second communication unit configured to perform out-of-band (OOB) connection; and
a controller configured to determine a location of the first electronic device via the OOB connection, select an applet in the first electronic device, based on information on the determined location, and perform, through the first communication unit, the UWB communication with a second electronic device adjacent to the determined location by using the selected applet,

wherein to perform the UWB communication with a second electronic device, the controller is configured to:
request slot allocation for the UWB communication to the second electronic device,
in response to the request, receive allocation of a slot for the UWB communication from the second electronic device, and
perform the UWB communication in the allocated slot.

8. The first electronic device of claim 7 , wherein the controller is configured to control the second communication unit to receive a Bluetooth advertisement message, and determine the location of the first electronic device, based on location information included in the received Bluetooth advertisement message.

9. The first electronic device of claim 8 , wherein the first electronic device is a mobile device, the second device is a gate within a station, and the location information included in the received Bluetooth advertisement message comprises identifier (ID) information of the station.

10. The first electronic device of claim 7 , wherein the information on the determined location is acquired from an application included in the first electronic device, based on the determined location.

11. The first electronic device of claim 10 , wherein the information on the determined location comprises at least one of identifier (ID) information of the second electronic device, address information of the second electronic device, condition information for accessing the second electronic device, condition information for selecting the applet, information of a UWB anchor adjacent to the determined location, and UWB block structure information.

12. The first electronic device of claim 11 ,
wherein the condition information for accessing the second electronic device comprises condition information related to a distance between the first electronic device and the second electronic device, and
wherein the distance between the first electronic device and the second electronic device is estimated based on at least one of downlink-time difference of arrival (DL-TDoA), a global positioning system (GPS), and a receiver signal strength indicator (RSSI).
