Description

Positioning method using wireless communication and an electronic device supporting the same

Various embodiments of the present invention relate to positioning technology using wireless communication.

In recent years, as wireless communication systems are rapidly developed, the demand for services using wireless communication has increased, and the spread of electronic devices including wireless communication modules has also increased. An electronic device supporting ultra-wideband (UWB) communication among various wireless communication methods may provide a precise positioning function. For example, the electronic device may measure the distance to the external electronic device through a ranging operation using UWB communication, and the direction ( or angle) can be determined (or measured). In addition, the electronic device may determine the location of the external electronic device based on the measured distance and direction of the external electronic device, and control the function of the external electronic device based on the location of the external electronic device or a location designated as the external electronic device base services can be provided.

Meanwhile, during positioning through UWB communication, an error may exist in the calculated AoA value due to signal interference according to the distance between antennas, a deviation in a process, or an actual measurement error according to an angle between the antennas and an external electronic device. Accordingly, in the process of the electronic device, a procedure for calibrating the above-described error may be performed.

However, since the existing calibration procedure aligns the positioning reference point with the center of the antennas, an error may occur in the positioning result for the external electronic device depending on the position where the positioning result is displayed. For example, since the distance and direction of the external electronic device are measured based on the UWB antenna, an error may exist in the positioning result displayed by the distance between the display and the antenna on which the positioning result is displayed. In particular, in the case of an electronic device in which the display area of the display is variable, such as a foldable, slideable, or rollable type, the distance between the display and the antenna may also vary, so that the positioning result is not affected. It may not be possible to provide a precise positioning function due to an error.

For example, when the electronic device 1100 is folded in the second direction, the compensation distance in the first direction (eg, the second distance 1107 ) is calculated when the specified angle 1111 is 90 degrees. value can be the same. Also, the electronic device 1100 may calculate a compensation distance in the second direction (eg, x + X' in FIG. 12 ) based on the specified angle 1111 .
