Triple-play protocol—a media access control layer protocol for transmissions in network-coded three node bidirectional cooperation
Abstract:
A method and apparatus are described including transmitting a request-to-send signal, determining if a clear-to-send signal and a reverse direction transmission request signal have been received, transmitting first data, a first block acknowledgement request signal and a reverse direction grant signal responsive to the first determination, determining if a first block acknowledgement signal, second data and a second block acknowledgement request signal have been received, transmitting a second block acknowledgement signal responsive to the second determination, determining if a third block acknowledgement signal has been received and transmitting a fourth block acknowledgement signal responsive to the third determination. Further described are a method and apparatus including listening to channels, estimating channel conditions responsive to the listening, determining if a signal has been received, determining if channel conditions are adequate to act as a relay node multicasting a relay node clear to send signal responsive to the first and second determinations and multicasting a block acknowledgement signal and data responsive to the first and second determinations.
