摘要： A wireless power transmission system, and a method and an apparatus for allocating a communication channel and transmitting a power in the wireless power transmission system. If a target device configured to wirelessly receive power from a source device is detected, a controlling communication channel to be used for performing communication with the target device is selected. An initial control signal including an identifier (ID) of the source device and a channel fix command are transmitted to the target device through the selected controlling communication channel. The channel fix command includes a command requesting the target device to use the selected controlling communication channel. A charging power is transmitted from the source device to the target device through a magnetic coupling between the source device and the target device.

摘要： A wireless power transmission device and method are provided. An amount of power transmitted wirelessly by the wireless power transmission device may be controlled based on information to be transmitted by the wireless power transmission device, such that the information may be transmitted without using any additional device for information transmission. Additionally, an internal impedance of a terminal may be controlled based on information to be transmitted by the terminal, and a reflected wave of a transmission signal transmitted by the wireless power transmission device may be then controlled, such that the information may be transmitted without using any additional device for information transmission. Therefore, no further device may be desired, and thus a power consumption amount may be reduced, and there may be no need to match a communication part for information exchange with a transmission part for wireless power transmission.
