1. A method of controlling power in a wireless power transmission apparatus, the method comprising:
- transmitting a wake-up power to a target device, the wake-up power being used to activate a communication function and a control function of the target device;
transmitting, by a source device, a request signal to the target device;
receiving, from the target device, a response signal corresponding to the request signal, the response signal comprising a parameter of the target device;
determining an amount of transmitted power of the source device based on a parameter of the source device and determining an amount of received power of the target device based on the parameter of the target device, wherein the transmitted power and the received power are associated with the wake-up power; and
generating an operating power based on the determined amount of transmitted power and the determined amount of received power.
