Abstract

L'invention concerne un procédé, un appareil et un système de modulation et codage d'ordre supérieur. Le procédé comprend l'étape suivante: une station de base envoie une signalisation de configuration à un terminal, la signalisation de configuration indiquant que la station de base sélectionne une forme améliorée prenant en charge un mode de modulation d'ordre M ou sélectionne une forme ordinaire ne prenant pas en charge le mode de modulation d'ordre M sur un ensemble de ressources prédéfini et/ou dans un mode de transmission prédéfini, la forme améliorée étant une table de CQI et/ou une table de MCS et/ou une table de TBS améliorées prenant en charge le mode de modulation d'ordre M, la forme ordinaire étant une table de CQI et/ou une table de MCS et/ou une table de TBS ordinaires ne prenant pas en charge le mode de modulation d'ordre M, et M étant supérieur ou égal à 256 et étant un entier positif.
