COMMUNICATION APPARATUS AND COMMUNICATION METHOD IN WIRELESS POWER TRANSFER SYSTEM

摘要

PURPOSE: A communication device and a communication method thereof are provided to request allocation for a channel which is not occupied by other devices by continuously transmitting alarm signals. CONSTITUTION: When all channels which are able to be used in a communication cell are allocated to a plurality of sources, a driving mode conversion unit(310) converts a driving mode into a transmission mode or a reception mode based on the set time. A transmission unit(350) transmits information related to the state of the occupied channel in the transmission mode by using a predetermined signal. A reception unit(360) receives a channel allocation request message from an additional source in a reception mode.
