Abstract

L'invention concerne des procédés et des montages dans un noeud de transmission (560) et un noeud de réception (540) dans un système de communication sans fil (500). Une pluralité de configurations de transmission est disponible pour transmettre un signal de transport d'informations du noeud de transmission au noeud de réception. Le noeud de transmission détermine (940) une pluralité de configurations d'extinction et sélectionne (950) une configuration de transmission. Chaque configuration d'extinction correspond à au moins une configuration de transmission. Le noeud de transmission transmet (960) au noeud de réception un message de configuration dynamique identifiant l'au moins une configuration d'extinction qui correspond à la configuration de transmission sélectionnée et transmet (970) le signal de transport d'informations au noeud de réception en fonction de la configuration de transmission sélectionnée. Le noeud de réception reçoit (910, 920) le message de configuration dynamique et le signal de transport d'informations et décode (930) le signal de transport d'informations reçu en tenant compte de l'au moins une configuration d'extinction.
