Techniques for indicating backscattering timing

An apparatus for wireless communication at an energy transferring device, comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• transmit a message that comprises timing information that indicates when backscattering of a wireless signal is to begin;
• transmit the wireless signal based at least in part on the message;
• and
• receive a backscattered signal based at least in part on a backscattering function that is applied to the wireless signal in accordance with the timing information.

A method for wireless communication at an energy harvesting device, comprising:

• receiving, from a wireless device, a message that comprises timing information that indicates when the energy harvesting device is to begin backscattering of a wireless signal of the wireless device;
• monitoring for the wireless signal from the wireless device based at least in part on the message;
• and
• transmitting a backscattered signal based at least in part on application of a backscattering function to the wireless signal in accordance with the timing information.
