The method and arrangement according to the present invention relates to of scheduling and coding in communication systems utilizing automatic repeat request (ARQ) and/or multihop scheduling and forwarding. According to the inventive method the receiving nodes selectively stores received information, also overheard information, as a priori information and feed back information about their respective stored a priori information to a sending node. The sending node forms composite data packets by jointly encoding and scheduling multiple data packets, which composite data packets are transmitted to receiving nodes. Upon receiving a composite data packet the receiving nodes uses their stored a priori information in the process of extracting data for themselves from the composite data packets.
Procédé et système pour l'ordonnancement et le codage dans les systèmes de communications, reposant sur la demande de répétition automatique (ARQ) et/ou l'ordonnancement et la retransmission multisauts. Selon le procédé décrit, les noeuds de réception enregistrent sélectivement l'information reçue, y compris l'information de service, en tant qu'information a priori, et envoient en retour à un noeud de transmission leur information a priori respectivement enregistrée. Le noeud de transmission forme des paquets de données composites, par codage et ordonnancement communs de plusieurs paquets de données, et ces paquets composites sont transmis aux noeuds de réception qui, à la réception de paquets composites, utilisent leur information a priori respectivement enregistrée dans l'extraction de données à laquelle ils procèdent pour eux-mêmes à partir des paquets composites.
