Abstract
The apparatus may be a reader device configured to transmit a first signal at a first frequency for a backscattering from an energy harvesting (EH) device over a plurality of frequencies, to receive, from an EH device, a backscatter signal over a plurality of frequencies based on a transmitted signal at a first frequency. The apparatus may further be configured to obtain channel state information (CSI) based on the backscattering of the first signal and to transmit an energy signal for the EH device via at least one frequency based on the CSI based on the backscatter signal. In an aspect of the disclosure, the apparatus may be an EH device configured to receive a transmitted signal at a first frequency and backscatter the transmitted signal over a plurality of frequencies and receive, from the reader, an energy signal based on the backscatter signal.
