1. A non-transitory computer-readable storage medium having instructions stored thereon which, when executed by one or more processors, cause the one or more processors to:
receive a first radio frequency (RF) signal comprising a first transport block;
receive, included in the first transport block, an acknowledgement instruction to enable acknowledgement (ACK) reflection;
perform, responsive to the receiving the acknowledgement instruction, a mirror reflection operation using backscatter communications to reflect an unaltered version of the first RF signal;
process the first RF signal to, thereby, generate a decoded transport block, wherein a first symbol of the decoded transport block implements, at least in part, physical downlink control channel (PDCCH) signaling;
receive a second RF signal after the receiving the first RF signal; and
reflect, based on the acknowledgement instruction, the second RF signal while altering the second RF signal to, thereby, produce an altered and reflected signal, wherein the altered and reflected signal includes an indication that the first transport block was correctly decoded.
