Hybrid waveforms for energy harvesting (eh)-capable devices

A wireless device, comprising:

• one or more memories storing processor-executable code;
• and
• one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the wireless device to:
• communicate control signaling indicating a set of waveform parameters associated with a hybrid waveform, the set of waveform parameters indicating a first time duration associated with a first reflection phase of the hybrid waveform and a second time duration associated with a second reflection phase of the hybrid waveform;
• transmit a signal to an energy harvesting-capable device;
• and
• receive a first hybrid waveform in accordance with the set of waveform parameters based at least in part on backscatter of the transmitted signal, wherein the first hybrid waveform transitions between the first reflection phase and the second reflection phase via a third reflection phase that has a first amplitude level that is between amplitude levels of the first and second reflection phases, and wherein the hybrid waveform comprises the first reflection phase for the first time duration and the second reflection phase for the second time duration.
