Abstract
Methods, systems, and devices for wireless communications are described. A network node may transmit a set of reference signals via a corresponding set of antennas, each antenna in the corresponding set of antennas associated with a unique precoding vector, wherein each precoding vector uses a combinational codeword based on a combination of codewords from a set of available codewords. The network node may receive, from an energy harvesting (EH)-capable device, a set of frequency-shifted backscatter responses corresponding to at least a subset of the set of reference signals. The network node may transmit, to the EH-capable device, a signal based on channel state information, wherein the channel state information is based on the set of frequency-shifted backscatter responses.
