Amplify and forward techniques to reduce collisions in wireless communication systems

A method for wireless communication, comprising:

• generating a sequence of preambles comprising an indication of at least one intended receiver for the sequence;
• transmitting the sequence of preambles to the at least one intended receiver over a radio frequency spectrum;
• and
• monitoring the radio frequency spectrum for a responsive transmission of an amplify and forward (AF) preamble by the at least one intended receiver after transmitting the sequence of preambles.

A method for wireless communication, comprising:

• receiving over a radio frequency spectrum, at a receiver, a sequence of preambles comprising an amplify and forward (AF) preamble and an indication of at least one intended receiver;
• determining that the receiver is an intended receiver based at least in part on the indication;
• amplifying the received AF preamble;
• and
• forwarding the amplified AF preamble over the radio frequency spectrum.
