Method for wireless charging and communication via clamping pulses

A method of operation of a wireless charger device, the method comprising:

• transmitting a wireless charging signal to a receiver device;
• receiving a clamping pulse from the receiver device based on the wireless charging signal, wherein the clamping pulse indicates a first value associated with a falling edge of the clamping pulse and further indicates a second value associated with a rising edge of the clamping pulse;
• detecting the clamping pulse based on a comparison of a first threshold with the first value and further based on a comparison of a second threshold with the second value, wherein the second threshold is different than the first threshold,
• wherein determining the first threshold and the second threshold includes:
• during a first window of a first duration, performing one or more first measurements of an output signal used to generate the wireless charging signal;
• during a second window of a second duration greater than the first duration, performing one or more second measurements of the output signal;
• based on the one or more first measurements, determining one or more first parameters associated with the output signal;
• based on the one or more second measurements, determining one or more second parameters associated with the output signal;
• configuring the first threshold based on the one or more first parameters;
• and
• configuring the second threshold based on the one or more second parameters;
• and
• determining a charging state of the receiver device based on the clamping pulse.
