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 channel search unit configured to search for communication channels other than a channel used in wireless power transmission, and measure state information of the communication channels;
a channel determining unit configured to determine a communication channel available for communication with a target device based on the measured state information;
a communication unit configured to transmit an access instruction to the target device using the determined communication channel; and
a controller configured to determine whether to communicate with the target device using the determined communication channel based on whether a response signal corresponding to the access instruction is received.

Abstract
An apparatus and method for performing communication in a wireless power transmission system are provided. The apparatus includes a channel search unit configured to search for communication channels other than a channel used in wireless power transmission, and measure state information of the communication channels. The apparatus includes a channel determining unit configured to determine a communication channel available for communication with a target device based on the measured state information. The apparatus includes a communication unit configured to transmit an access instruction to the target device using the determined communication channel. The apparatus includes a controller configured to determine whether to communicate with the target device using the determined communication channel based on whether a response signal corresponding to the access instruction is received.
