1. A method of a wireless power transmitter for transmitting wireless power to at least one wireless power receiver, the method comprising:
- setting, by the wireless power transmitter, a search channel to be used for communication with the at least one wireless power receiver, wherein the search channel is predetermined according to a first communication scheme;
detecting at least one of an energy level of a signal received on the search channel and a Received Signal Strength Indication (RSSI) value of the signal received on the search channel, wherein the signal is generated by another electronic device using a second communication scheme; and
determining whether to designate the search channel as a communication channel based on the detection results,wherein the another electronic device is separated from the wireless power transmitter or the wireless power receiver, andwherein the first communication scheme is different from the second communication scheme.

14. A wireless power transmitter for transmitting wireless power to at least one wireless power receiver, the wireless power transmitter comprising:
-
a controller that sets a search channel to be used for communication with the at least one wireless power receiver, wherein the search channel is predetermined according to a first communication scheme; and a communication unit that receives a signal on the search channel, wherein the signal is generated by another electronic device using a second communication scheme; wherein the controller detects at least one of an energy level of the received signal and a Received Signal Strength Indication (RSSI) value of the received signal, and determines whether to designate the search channel as a communication channel, based on the detection results, wherein the another electronic device is separated from the wireless power transmitter or the wireless power receiver, and wherein the first communication scheme is different from the second communication scheme. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
