1. A wireless power transmission control method, comprising:
- transmitting a wake-up request signal that is used to wake up a target device;
receiving a response message from the target device that is activated by the wake-up request signal;
setting a demand power based on the response message; and
transmitting a resonance power to the target device based on the set demand power.

Abstract
Provided are a wireless power transmission control method and wireless power transmission control apparatuses. The wireless power transmission control method may include transmitting a wake-up request signal used to wake up a target device, and receiving a response message from the target device activated by the wake-up request signal. A source device may set a demand power based on the response message, and may transmit a resonance power to the target device based on the demand power.

14. A wireless power transmission control apparatus, comprising:
-
a target resonator operated at a same resonance frequency as a source resonator; a communication unit to receive a wake-up request signal from a source device, and to transmit a response message to the wake-up request signal to the source device; and a controller that is activated by a resonance power comprised in the wake-up request signal, and configured to generate the response message, wherein the response message comprises an identification (ID) of a target device and information about an amount of power to be used by the target device.
