Classification: CPC H | IPC H

Claim 15:
16. A non-transitory computer-readable storage medium that stores instructions for execution by processing circuitry of an RF repeater configured for semantic-less retransmissions, wherein the processing circuitry is configured to:
perform physical (PHY) layer processing to identify one or more residual indicators present in of a received RF signal; and
determine 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 processing circuitry is to:
refrain 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;
authenticate the received RF signal based on one or more authentication features determined from the residual indicators;
determine, 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
refrain from retransmitting the received RF signal when not authenticated.
