Abstract
Improving backscattering and, specifically, a physical Layer transmit mode for improving the Signal-to-Interference Ratio (SIR) of backscatter signals may be provided. A transmitter may determine a Backscatter Device (BKD) to send a transmission to for backscattering. The transmitter may determine a width of a puncture in the transmission. Next, the transmitter may transmit the transmission to the BKD. The transmitter may receive feedback from a receiver about decoding a backscattered signal generated using the transmission. The transmitter may adjust the width of the puncture for a subsequent transmission based on the feedback.
