CONTROL INFORMATION ACQUISITION BASED ON BACKSCATTERING FOR A WIDEBAND CHANNEL

Systems and techniques are provided for wireless communication. For example, a network device can transmit radio frequency (RF) signals. Each RF signal of the RF signals is associated with a respective sub-band of sub-bands included in a wideband bandwidth. The network device can receive, from an energy harvesting (EH)-capable device, backscatter RF signals. Each backscatter RF signal of the backscatter RF signals is associated with a respective RF signal of the RF signals. Each backscatter RF signal and each respective RF signal are associated with a respective sub-band of the sub-bands included in the wideband bandwidth. The network device can determine control information associated with the wideband bandwidth based on the backscatter RF signals.
