1. A method of transmitting wireless power, 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, wherein the response message comprises an identification (ID) of the target device and information associated with an amount of power to be used by the target device, wherein the ID of the target device includes a type of the target device;
setting a demand power based on the response message;
transmitting the wireless power to the target device based on the set demand power;
receiving at least one check message including a power receiving state of the target device periodically; and
adjusting the wireless power based on the check message.

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.
