Abstract

La présente demande concerne des procédés et un appareil de traitement d'informations, un dispositif et un support d'enregistrement, qui se rapportent au domaine des communications mobiles. Un procédé comprend : la détermination d'un premier débit de codage correspondant à de premières informations, le premier débit de codage étant la valeur la plus petite parmi un premier débit de codage préconfiguré et un second débit de codage, le nombre de premiers bits des premières informations étant O1, le nombre de bits codés des premières informations après leur codage étant N1, à la fois O1 et N1 étant des nombres entiers positifs, et le second débit de codage étant le rapport de O1 à N1. Un nouveau moyen permettant de déterminer le débit de codage est décrit. Le débit de codage réel des premières informations peut être déterminé par combinaison du débit de codage préconfiguré et du second débit de codage, de sorte qu'il n'est pas nécessaire que le débit de codage des premières informations soit le débit de codage préconfiguré, ce qui permet d'améliorer la flexibilité.
