Abstract
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.
