Low latency ack/nack transmission

An apparatus comprising:

• a memory storing computer-executable instructions;
• a processor adapted, by executing the computer-executable instructions, to:
• receive a first radio frequency (RF) signal including a first transport block;
• attempting, by the apparatus, to demodulate and decode the first transport block from the first RF signal;
• receive a second RF signal after the first RF signal;
• and
• reflect the second RF signal while altering the second RF signal, the altered and reflected second RF signal including a first feedback indicative of whether the first transport block was correctly or incorrectly demodulated and decoded by the apparatus.

A method, at an apparatus, of receiving acknowledgement (ACK) or negative acknowledgement (NACK) transmissions, the method comprising:

• transmitting, by the apparatus, a first radio frequency (RF) signal comprising a first transport block;
• transmitting, by the apparatus, a second RF signal after the first RF signal;
• and
• receiving, by the apparatus, an altered and reflected version of the second RF signal including a first feedback indicative of whether the first transport block was correctly or incorrectly demodulated and decoded.
