1. A method, executed by a power receiver, of controlling wireless power reception, the method comprising:
- receiving wireless power from a power transmitter, the wireless power having a different resonance frequency for each of a plurality of time intervals;
receiving, from the power transmitter, a message identifying the resonance frequency and wireless power transmitted, in each of the time intervals; and
transmitting information about amounts of power received respectively corresponding to resonance frequencies used in the time intervals.
