COMMUNICATION APPARATUS AND COMMUNICATION METHOD IN WIRELESS POWER TRANSMISSION SYSTEM
First Claim
1. A communication apparatus in a wireless power transmission system, the communication apparatus comprising:
- a communication unit configured to transmit a state information signal using a frequency of a communication channel, wherein the communication channel is selected from channels excluding a channel used in wireless power transmission, and the state information signal comprises an operating mode of a source; and
a controller configured to determine a control identifier (ID) of a target when a response signal corresponding to an access standard instruction is received from the target.

Abstract
An apparatus and method to perform communication in a wireless power transmission system are provided. When a communication channel is selected from channels excluding a channel used in wireless power transmission, a communication apparatus and method transmit, using a frequency of the communication channel, a channel seizure signal, an access standard instruction, and a state information signal indicating an operating mode of a source. When a response signal corresponding to the access standard instruction is received from a target, the communication apparatus and method determine a control identifier (ID) of the target.

29. A communication apparatus in a wireless power transmission system, the communication apparatus comprising:
-
a communication unit configured to transmit a channel seizure signal, a first access standard instruction, and a first state information signal using a frequency of a communication channel, wherein the communication channel is selected from channels excluding a channel used in wireless power transmission, and the first state information signal comprises an operating mode of a source; and a controller configured to receive a response signal corresponding to the first instruction from a first target to determine a control identifier (ID) of the first target, wherein, when the determined control ID of the first target is transmitted, the communication unit is further configured to transmit the channel seizure signal, a second access standard instruction, and a second state information signal using the frequency of the communication channel, and wherein, when a response signal corresponding to the second access standard instruction is received from a second target, the controller is further configured to determine a control ID of the second target. - View Dependent Claims (30, 31, 32)
