METHOD FOR TRANSMITTING SIGNALS FROM A PLURALITY OF WIRELESS POWER RECEIVERS TO WIRELESS POWER SUPPLIER
First Claim
1. A method of transmitting a signal from a wireless power receiver, the method comprising the steps of:
- receiving a signal comprising at least one of a power supply signal for wireless charging from a wireless power supplier and a power communication signal from at least one external wireless power receiver;
analyzing the received signal to determine whether the power communication signal is included with the power supply signal in the received signal;
determining a transmission frequency of a transmission signal based on whether the power communication signal is included with the power supply signal in the received signal; and
modulating transmission data for control of the wireless charging, and outputting the modulated transmission data as the transmission signal over the transmission frequency.

Abstract
Methods and apparatus are provided for transmission and reception of signals. A signal is received that includes at least one of a power supply signal for wireless charging from a wireless power supplier and a power communication signal from at least one external wireless power receiver. The received signal is analyzed to determine whether the power communication signal is included with the power supply signal in the received signal. A transmission frequency of a transmission signal is determined based on whether the power communication signal is included with the power supply signal in the received signal. Transmission data for control of the wireless charging is modulated, and the modulated transmission data is output as the transmission signal over the transmission frequency.
