1. An apparatus for wireless communication at a first device, comprising:
one or more memories;
one or more processors coupled with the one or more memories and configured to cause the first device to:
transmit, to a second device, an indication of an energy conversion efficiency factor and a threshold power parameter, wherein the threshold power parameter is a characteristic of an energy harvesting circuit of the first device; and
receive, from the second device, a signal comprising a radio frequency power that is based at least in part on the transmitted indication; and
the energy harvesting circuit, coupled with the one or more processors and the one or more memories, configured to convert at least a first portion of the radio frequency power of the signal to direct current power.
