Triple-play protocol—a media access control layer protocol for transmissions in network-coded three node bidirectional cooperation

An apparatus for transmitting first data from a first node to a second node and transmitting second data from said second node to said first node via a relay node, said apparatus comprising a first node including a control logic and a transceiver, wherein

• said transceiver transmits a request-to-send signal;
• said control logic determines during a first determination if a clear-to-send signal and a reverse direction transmission request signal have been received;
• said transceiver transmits first data, a first block acknowledgement request signal and a reverse direction grant signal responsive to said first determination;
• said control logic determines during a second determination if a first block acknowledgement signal, second data and a second block acknowledgement request signal have been received;
• said transceiver transmits at least one of a relay node request to send signal and a second block acknowledgement signal responsive to said second determination;
• said control logic determines during a third determination if a third block acknowledgement signal has been received and wherein said control logic further determines if a relay node clear to send signal has been received;
• and
• said transceiver transmits a fourth block acknowledgement signal responsive to said third determination.

A method for transmitting first data from a first node to a second node and transmitting second data from said second node to said first node via a relay node, said method comprising a first node including a control logic and a transceiver, wherein, said method comprising, at the second node:

• first determining, by the second node, if a request to send signal has been received;
• first transmitting, by the second node, a clear to send signal and a reverse direction transmission request signal responsive to said first determination;
• second determining, by the second node, if said first data, a first block acknowledgement request signal and a reverse direction transmission grant signal have been received;
• second transmitting, by the second node, first block acknowledgement signal, said second data and a second block acknowledgement request responsive to said second determination;
• third determining, by the second node, if a second block acknowledgement signal and third data have been received, wherein one of said first determination and said third determination further comprises determining if a relay node clear to send signal has been received;
• and
• third transmitting, by the second node, a third block acknowledgement signal responsive to said third determination.

An apparatus for transmitting first data from a first node to a second node and transmitting second data from said second node to said first node via a relay node, said apparatus comprising a first node including a control logic and a transceiver, wherein

• said control logic determines during a first determination if a request to send signal has been received;
• said transceiver transmits a clear to send signal and a reverse direction transmission request signal responsive to said first determination;
• said control logic determines during a second determination if first data, a first block acknowledgement request signal and a reverse direction transmission grant signal have been received;
• said transceiver transmits a first block acknowledgement signal, said second data and a second block acknowledgement request responsive to said second determination;
• said control logic determines during a third determination if a second block acknowledgement signal and third data have been received, wherein one of said first determination and said third determination further comprises said control logic determining if a relay node clear to send signal has been received;
• and
• said transceiver transmits a third block acknowledgement signal responsive to said third determination.

A method for transmitting first data from a first node to a second node and transmitting second data from said second node to said first node via a relay node, said method comprising, at the relay node:

• listening, by the relay node, to channels;
• first receiving, by the relay node, the first data from the first node;
• second receiving, by the relay node, said second data from the second node;
• first determining if the relay node overhears at least one of a first block acknowledgement from the first node and a second block acknowledgement from said second node;
• second determining, by the relay node, if a signal has been received wherein said signal is one of a relay node request to send signal and a request to send signal;
• third determining if channel conditions are adequate to act as the relay node responsive to said listening;
• multicasting a relay node clear to send signal responsive to said first and second determinations;
• and
• multicasting a block acknowledgement signal and third data responsive to said first and second determinations, wherein said third data is a combination of corrupted portions of said first data and corrupted portions of said second data.
