Power harvesting protocol for configurable metasurfaces in a wireless wide area network (WWAN)

A method for wireless communication performed by an apparatus of a channel engineering device (CED), comprising:

• transmitting a power harvesting capabilities message to a network entity, the power harvesting capabilities message indicating capabilities for power harvesting at the CED, wherein the power harvesting capabilities message includes one or more parameters selected by the CED that indicate capabilities for power harvesting at the CED, the one or more parameters including an aperture size parameter that indicates a first aperture size associated at least in part with a material of the CED;
• receiving a power harvesting configuration message from the network entity;
• configuring the CED for one or more power harvesting signals associated with the power harvesting configuration message;
• and
• receiving, the one or more power harvesting signals associated with the power harvesting configuration message from the network entity using a beam, wherein the beam is based at least in part on transmitting the aperture size parameter.

An apparatus of a network entity for wireless communication, comprising:

• one or more processors configured to implement a power harvesting protocol;
• and
• one or more interfaces configured to:
• receive a power harvesting capabilities message from a channel engineering device (CED), wherein the power harvesting capabilities message includes one or more parameters selected by the CED that indicate capabilities for power harvesting at the CED, the one or more parameters including an aperture size parameter that indicates a first aperture size associated at least in part with a material of the CED;
• transmit a power harvesting configuration message associated with the power harvesting capabilities message to the CED, the power harvesting configuration message indicating timing information associated with power harvesting signals used by the CED for power harvesting;
• and
• transmit one or more power harvesting signals to the CED using a beam, wherein the beam is based at least in part on receiving the aperture size parameter.
