==Original Abstract Submitted==

methods, systems, and devices for wireless communications are described. a network node may determine channel state information (csi) for a link with an energy harvesting (eh)-capable device based on measurements of backscattered signals reflected from the eh-capable device. the network node may include multiple antennas and may indicate, to the eh-capable device, a frequency shift to be applied by the eh-capable device to backscattering. the network node may transmit reference signals from each antenna of the network node. the eh-capable device may backscatter the received reference signals in accordance with the indicated frequency shift, and the network node may measure the frequency-shifted backscattered responses to the reference signals to determine csi between the different antennas and the eh-capable device. based on the identified csi, the network node may perform channel selection and/or spatial beamforming to increase received power at the eh-capable device for downlink transmissions to the eh-capable device.
