APPARATUS AND METHOD TO PERFORM COMMUNICATION IN WIRELESS POWER TRANSMISSION SYSTEM
First Claim
1. A source device of a wireless power transmission system, the source device comprising:
- a communication unit configured to transmit an access standard instruction on a communication channel having a frequency that is not used for wireless power transmission; and
a controller configured toassign, to a target device, a control identifier (ID) if a response signal responding to the access standard instruction is received from the target device, anddetermine an initial wireless power to be transmitted to the target device based on a change in a temperature of the source device, or a battery state of the target device, or a change in an amount of a power received by the target device, or a change in a temperature of the target device, or any combination thereof.

Abstract
An apparatus and method to perform communication in a wireless power transmission system are provided. A source device of the wireless power transmission system, includes a communication unit configured to transmit an access standard instruction on a communication channel having a frequency that is not used for wireless power transmission. The source device further includes a controller configured to assign, to a target device, a control identifier (ID) if a response signal responding to the access standard instruction is received from the target device. The controller is further configured to determine an initial wireless power to be transmitted to the target device based on a change in a temperature of the source device, or a battery state of the target device, or a change in an amount of a power received by the target device, or a change in a temperature of the target device, or any combination thereof.

7. A target device of a wireless power transmission system, the target device comprising:
-
a communication unit configured to receive, from a source device, a channel occupancy signal and an access standard instruction, using a frequency of a communication channel, and transmit, to the source device, a response signal responding to the access standard instruction; a controller configured to determine the communication channel as a channel used to communicate with the source device based on the channel occupancy signal, and generate the response signal responding to the access standard instruction; and a target resonator configured to receive, from the source device, an initial wireless power determined based on a change in a temperature of the source device, or a battery state of the target device, or a change in an amount of a power received by the target device, or a change in a temperature of the target device, or any combination thereof. - View Dependent Claims (8, 9, 10, 11, 12)
