Abstract

A method for operating an electronic device is provided. The method includes monitoring a noise level of a noise signal received via a panel while wireless power is transmitted and/or received at a first power level via at least a conductive pattern, and generating a signal for changing the first power level corresponding to at least a part of an input to at least a part of the panel.

Claims

1. An electronic device comprising:

a panel configured to detect a change of an external magnetic field;

a wireless power circuit;

a conductive pattern electrically connected to the wireless power circuit;

a processor electrically connected to the panel and to the wireless power circuit; and

a memory electrically connected to the processor,

wherein the memory stores instructions for instructing, when being executed, the processor to;

monitor a noise level of a noise signal, which is generated by an input that is received via the panel, while wireless power is transmitted and/or received at a first power level through the conductive pattern, and

generate a signal for changing the first power level to a second power level, which is less than the first power level, based on a location of the input on the panel to reduce interference from the wireless power being transferred at the location of the input.

2. The electronic device of claim 1, wherein the memory stores instructions for instructing, when being executed, the processor to maintain an intensity of a wireless charging current so that wireless charging of the first power level is performed if the noise level is lower than a specified value.

3. The electronic device of claim 1, wherein the memory stores instructions for instructing, when being executed, the processor to lower an intensity of a wireless charging current so that wireless charging of the second power level, which is less than the first power level, is performed if the noise level is higher than a specified value.

4. The electronic device of claim 3, further comprising:

a plurality of wireless power antennas configured to receive the wireless power; and

a switch configured to select at least one of the plurality of wireless power antennas,

wherein the memory stores instructions for instructing, when being executed, the processor to select at least a portion of the plurality of wireless power antennas by controlling the switch to reduce an antenna size for transmitting/receiving the wireless power.

5. The electronic device of claim 1, wherein the memory stores instructions for instructing, when being executed, the processor to perform a wireless charging of a specified power level corresponding to the noise level.

6. The electronic device of claim 1, wherein the memory stores instructions for instructing, when being executed, the processor to transmit a signal for requesting adjustment of a wireless charging current to a wireless charging device.

7. The electronic device of claim 6, wherein the memory stores instructions for instructing, when being executed, the processor to transmit, to the wireless charging device, at least one of a signal for requesting reduction of transmission power, a signal for requesting reduction of a size of a transmitter coil, or a signal for requesting a change of a transmission frequency.

8. The electronic device of claim 1, wherein the memory stores instructions for instructing, when being executed, the processor to output guide information for changing a charging current if an input occurs on a panel area from which a noise of a specified noise level or higher is measured.

9. The electronic device of claim 8, wherein the memory stores instructions for instructing, when being executed, the processor to display the guide information on a location of the input or an adjacent area thereto.

10. The electronic device of claim 1, wherein the memory stores instructions for instructing, when being executed, the processor to output an alarm about a state of arrangement of the electronic device and a wireless charging device on a basis of a distribution state of the noise level.

11. A method for operating an electronic device, the method comprising:

monitoring, by the electronic device, a noise level of a noise signal, which is generated by an input that is received via a panel, while wireless power is transmitted and/or received at a first power level through a conductive pattern; and

generating, by the electronic device, a signal for changing the first power level to a second power level, which is less than the first power level, based on a location of the input from on the panel to reduce interference from the wireless power being transferred at the location of the input.

12. The method of claim 11, wherein the generating comprises maintaining a wireless charging state of the first power level if the noise level is lower than a specified value.

13. The method of claim 11, wherein the generating comprises reducing an intensity of a wireless charging current so that wireless charging corresponding to the second power level different from the first power level is performed if the noise level is higher than a specified value.

14. The method of claim 13, wherein the reducing comprises reducing a size of a wireless power antenna.

15. The method of claim 11, wherein the generating comprises collecting a wireless charging current of a specified intensity according to the noise level.

16. The method of claim 11, wherein the generating comprises transmitting, to a wireless charging device, a signal for requesting adjustment of a wireless charging current.

17. The method of claim 16, wherein the transmitting of the signal to the wireless charging device comprises transmitting, to the wireless charging device, at least one of a signal for requesting reduction of transmission power, a signal for requesting reduction of an area of a transmitter coil, or a signal for requesting a change of a transmission frequency.

18. The method of claim 11, further comprising:

outputting guide information for changing a charging current if an input occurs on a panel area from which a noise of a specified noise level or higher is measured.

19. The method of claim 18, wherein the outputting comprises displaying the guide information on a location of the input or an adjacent area thereto.

20. The method of claim 11, further comprising:

outputting an alarm about a state of arrangement of the electronic device and a wireless charging device according to a distribution state of the noise level.
