Abstract

La présente invention concerne un procédé et dispositif de communication sans fil. Dans un mode de réalisation, un premier nœud émet K informations statistiques a priori lors de la première étape, et envoie K points d'informations statistiques a priori respectivement à K blocs de bits, K étant un entier positif et les informations statistiques a priori comprenant des deuxièmes informations: au moins une information parmi {une valeur moyenne de premiers paramètres, une variance des premiers paramètres}, et les premiers paramètres sont des longueurs de chaînes de bits d'un premier état. Le premier état et un deuxième état sont des états qui peuvent être indiqués respectivement par un bit binaire. La chaîne de bits est composée de bits binaires consécutifs présentant le même état, et l'état d'un bit adjacent de la chaîne de bits change. La présente invention peut améliorer efficacement les performances du décodage de canaux dans l'hypothèse d'une occupation supplémentaire de ressources plus réduites d'interface radio.
