1. A method comprising:
determining a Backscatter Device (BKD) to send a transmission to for backscattering;
determining a width of a puncture in the transmission;
transmitting the transmission to the BKD;
receiving feedback from a receiver about decoding a backscattered signal generated using the transmission; and
adjusting the width of the puncture for a subsequent transmission based on the feedback.
