METHOD OF PERFORMING BIDIRECTIONAL COMMUNICATION BETWEEN TRANSMITTER AND RECEIVER IN WIRELESS POWER TRANSMISSION/RECEPTION SYSTEM, THE TRANSMITTER, AND THE RECEIVER

摘要

A method and apparatus for performing bidirectional communication between a transmitter and a receiver in a wireless power transmission systemare provided. The method includes detecting the receiver; transmitting, when the receiver is detected, transmitting a predetermined level of power to the receiver through a transmission (Tx) resonator; receiving a request for transmitting wireless power from the receiver through a wireless communication module; allocating a Short IDentification (SID) and a time slot corresponding to the receiver; transmitting the SID and the time slot to the receiver through the wireless communication module; receiving a request for required power from the receiver through the wireless communication module; determining whether the required power is greater than a residual power of the transmitter; and when the required power is greater than the residual power, informing the receiver through the wireless communication module that the required power cannot be transmitted.
