## Abstract

The present disclosure provides a method for controlling a non-UWB device by using a UWB. A method of a first UWB device, of the present disclosure, may comprise the steps of: identifying the location of a non-UWB device based on the location of a second UWB device on the basis of the UWB ranging between the first UWB device and the second UWB device; and recognizing the non-UWB device on the basis of the pointing direction of the first UWB device and the identified location of the non-UWB device.

## Claims

### Claim 1

A method by a first ultra-wide band (UWB) device, the method comprising:
identifying a position of a non-UWB device with respect to a position of a second UWB device based on UWB ranging between the first UWB device and the second UWB device; and
recognizing the non-UWB device based on a point direction of the first UWB device and the identified position of the non-UWB device.

### Claim 2 (depends on 1)

The method of claim 1,
wherein identifying the position of the non-UWB device includes identifying a position of the first UWB device with respect to the position of the second UWB device using a result of the UWB ranging, and
wherein the result of the UWB ranging includes at least one of time-of-flight (ToF) information, angle-of-arrival (AoA) azimuth information, and AoA elevation information.

### Claim 3 (depends on 2)

The method of claim 2, wherein identifying the position of the non-UWB device includes:
obtaining inclination information about the first UWB device pointing at the non-UWB device within a preset distance; and
identifying the position of the non-UWB device with respect to the position of the second UWB device based on the AoA azimuth information, the preset distance, and the inclination information.

### Claim 4 (depends on 1)

The method of claim 1,
wherein identifying the position of the non-UWB device includes:
identifying a first position of the first UWB device with respect to the position of the second UWB device using a result of the UWB ranging at the first position, and
identifying a second position of the first UWB device with respect to the position of the second UWB device using a result of the UWB ranging at the second position, and
wherein the result of the UWB ranging at the first position includes first time-of-flight (ToF) information, first angle-of-arrival (AoA) azimuth information, and first AoA elevation information about the first position, and the result of the UWB ranging at the second position includes second ToF information, second AoA azimuth information, and second AoA elevation information about the second position.

### Claim 5 (depends on 4)

The method of claim 4, wherein identifying the position of the non-UWB device includes:
obtaining first inclination information about the first UWB device pointing at the non-UWB device from the first position and second inclination information about the second UWB device pointing at the non-UWB device from the second position; and
identifying the position of the non-UWB device with respect to the position of the second UWB device by obtaining an intersection of a first straight line pointing at the non-UWB device from the first position and a second straight line pointing at the non-UWB device from the second position, based on the first AoA azimuth information, the second AoA azimuth information, the first inclination information, and the second inclination information.

### Claim 6 (depends on 1)

The method of claim 1, wherein the UWB ranging is performed based on a two-way ranging (TWR) scheme.

### Claim 7 (depends on 1)

The method of claim 1, wherein recognizing the non-UWB device includes providing control information for controlling the recognized non-UWB device.

### Claim 8 (depends on 1)

The method of claim 1, wherein identifying the position of the non-UWB device is performed to register the non-UWB device as a target device for control by the first UWB device.

### Claim 9

A first UWB device, comprising:
a memory; and
a transceiver; and
a controller connected to the memory and the transceiver, wherein the controller is configured to:
identify a position of a non-UWB device with respect to a position of a second UWB device based on UWB ranging between the first UWB device and the second UWB device, and
recognize the non-UWB device based on a point direction of the first UWB device and the identified position of the non-UWB device.

### Claim 10 (depends on 9)

The first UWB device of claim 9,
wherein the controller is configured to identify a position of the first UWB device with respect to the position of the second UWB device using a result of the UWB ranging, and
