Two-way communication using wireless power signal
First Claim
1. A wireless power transmitter, comprisinga power transmission controller which generates a packet for one or more electronic devices, wherein the one or more electronic devices comprises a first electronic device and a second electronic device and the packet comprises a first packet transmitted to the first electronic device and a second packet transmitted to the second electronic device;
- a modulation/demodulation unit which modulates a carrier signal to contain the generated packet; and
a power conversion unit which forms a wireless power signal for power transmission based on the modulated carrier signal,wherein the power transmission controller transmits the first packet to the first electronic device, waits for a first response from the first electronic device for a first expiration period of time, transmits the second packet to the second electronic device when the first response is not received, and waits for a second response from the second electronic device for a second expiration period of time, andwherein the second packet is transmitted after the first expiration period of time for the first response.

Abstract
The present description relates to an apparatus for transmitting wireless power and a method for same, comprising: a power transmission control portion for generating a packet comprising data for at least one electronic device; a modulation/demodulation portion for modulating a carrier signal so as to comprise the packet that is generated; and a power conversion portion for forming the wireless power signal for transmitting power, based on the carrier signal that is modulated, wherein the power transmission control portion transmits the packet to the at least one electronic device through the wireless power signal. Also, the present description relates to the electronic device and a method for receiving power by same, comprising: a power reception portion for receiving the wireless power signal from the apparatus for transmitting wireless power; a modulation/demodulation portion for demodulating the packet which is comprised in the wireless power signal; and a power reception control portion for obtaining data based on the packet that is demodulated.
