Claim 10:
11. A method for semantic-less retransmissions comprising:
performing physical (PHY) layer processing to identify one or more residual indicators present in a received RF signal; and
determining whether or not to retransmit the received RF signal based on the one or more residual indicators,
wherein the residual indicators result from an electromagnetic transmission of the received RF signal by a transmitter performing one or more of upconversion, modulation and amplification,
wherein the method further comprises:
refraining from performing processing at any one or more logical layers higher than a PHY layer, including refraining from performing medium access control (MAC) layer processing to determine whether or not to retransmit the received RF signal;
authenticating the received RF signal based on one or more authentication features determined from the residual indicators;
determining, if the received RF signal is authenticated, whether or not to retransmit the received RF signal based on one or more retransmission features determined from the residual indicators; and
refraining from retransmitting the received RF signal when not authenticated.
