Abstract[English]
Methods and apparatuses for network coding with a retransmission scheme are described. A first packet intended for a first destination node and a second packet intended for a second destination node are obtained. An initial transmission of the first packet to the first and second destination nodes is performed, and an initial transmission of the second packet to the first and second destination nodes is performed. A retransmission to the first and the second destination nodes is performed, where performing the retransmission includes generating cross-packet coded bits using a combination of one or more bits from the first packet and one or more bits from the second packet, where the cross-packet coded bits are scrambled using an identifier known to both the first and second destination nodes, and where the cross-packet coded bits, after scrambling, are used for the retransmission.[French]
L'invention concerne des procédés et des appareils de codage réseau avec un schéma de retransmission. Un premier paquet destiné à un premier nœud de destination et un second paquet destiné à un second nœud de destination sont obtenus. Une transmission initiale du premier paquet vers les premier et second nœuds de destination est effectuée, et une transmission initiale du second paquet vers les premier et second nœuds de destination est effectuée. Une retransmission vers les premier et second nœuds de destination est effectuée, la retransmission consistant à générer des bits codés en paquets croisés à l'aide d'une combinaison d'un ou de plusieurs bits du premier paquet et d'un ou de plusieurs bits du second paquet, les bits codés en paquets croisés étant brouillés à l'aide d'un identifiant connu à la fois des premier et second nœuds de destination, et les bits codés en paquets croisés étant utilisés, après brouillage, pour la retransmission.
