METHOD OF PERFORMING BIDIRECTIONAL COMMUNICATION BETWEEN TRANSMITTER AND RECEIVER IN WIRELESS POWER TRANSMISSION/RECEPTION SYSTEM, THE TRANSMITTER, AND THE RECEIVER
First Claim
1. A method of performing bidirectional communication by a transmitter in a wireless power transmission/reception system, the method comprising:
- detecting a receiver;
transmitting, when the receiver is detected, 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.

Abstract
A method and apparatus for performing bidirectional communication between a transmitter and a receiver in a wireless power transmission system are 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.

7. A transmitter in a wireless power transmission/reception system, the transmitter comprising:
-
a transmission (Tx) resonator for transmitting a predetermined level of power to a receiver, upon a detection of the receiver; a wireless communication module for receiving, from the receiver, a request for transmitting wireless power; and a Tx Micro Control Unit (MCU) for allocating, when receiving the request for transmitting the wireless power from the receiver through the wireless communication module, a Short IDentification (ID) 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 informing the receiver through the wireless communication module that the required power cannot be transmitted when the required power is greater than the residual power. - View Dependent Claims (8, 9, 10, 11, 12)
