The invention proposes a method for the transmission of data in a cooperative network comprising a source terminal (S), a destination terminal (D) and a relay terminal (R), comprising:
in a first transmission (T1), the transmission of the data of a packet by the source terminal (S) to both the relay terminal (R) and the destination terminal (D);in the event of failure (N1) of the destination terminal (D) to successfully decode the data in the packet of the first transmission, and in the case of the data of the first transmission being successfully (O2) decoded by the relay terminal (R), the relay terminal transmits the data of the packet to the destination terminal in a second transmission (T2);in the event of failure (N3) of the destination terminal to successfully decode the data in the packet of the second transmission (T2), selection of the source terminal and/or relay terminal to retransmit the data of the packet to the destination terminal in a third transmission (T3), where the selection may be based on an assessment of the reliability of the transmission channel between the source terminal and the destination terminal and of the transmission channel between the relay terminal and the destination terminal. |

1. A method for the transmission of a sequence made up of multiple data packets in a cooperative network comprising multiple nodes, including a source terminal, a destination terminal and a relay terminal, said method comprising:
in a first transmission, transmitting data of a packet by the source terminal to both the relay terminal and the destination terminal; in the event of failure of the destination terminal to successfully decode the data in the packet of the first transmission, and in the case of the data of the first transmission being successfully decoded by the relay terminal, the relay terminal transmits the data of the packet to the destination terminal in a second transmission; in the event of failure of the destination terminal to decode the data in the packet of the second transmission, selecting the source terminal and/or of the relay terminal to retransmit the data of the packet to the destination terminal in a third transmission;wherein the cooperative network implements a distributed encoding, according to which the source terminal implements encoding of the data of the packet of the first transmission using a first encoder, and according to which in the event of successful decoding of the data of the packet of the first transmission by the relay terminal, the relay terminal interlaces the decoded data to form an interlaced data packet and implements an encoding of said interlaced data packet using a second encoder for the purposes of the second transmission of the data of the packet; andwherein in the event of unsuccessful decoding by the destination terminal of the data of the packet in the second transmission or of the data of the packet of the third transmission, the destination terminal generates and transmits to the source terminal and to the relay terminal a message for disconfirming of the decoding indicating which of the relay terminal and/or of the source terminal is selected for retransmitting, in a third transmission, the data of the packet to the destination terminal, said disconfirming message also indicating whether the data of the packet to be retransmitted in a third transmission are data from the packet of the first transmission or data from the packet of the second transmission. |
