1. A method for wireless communication at an energy transmitter device, comprising:
transmitting an energy signal to an energy receiver device via a channel, the energy signal providing energy from the energy transmitter device for energy harvesting at the energy receiver device during one or more energy harvesting intervals;
transmitting, to the energy receiver device, a first signal separate from the energy signal;
receiving, from the energy receiver device, a second signal from which the energy transmitter device determines channel state information of the channel, the channel state information based at least in part on the first signal; and
transmitting, to the energy receiver device, one or more additional signals whose transmission characteristics are based at least in part on the channel state information.
