Abstract

Un mode de réalisation de la présente invention concerne le domaine technique des communications, et concerne ainsi un procédé, un dispositif et un système de transmission de données de sorte à résoudre le problème dans lequel le nombre de LCID réservés peut ne pas satisfaire une exigence d'expansion, ne permettant ainsi pas de fournir une meilleure qualité de service. Le procédé consiste à : obtenir un premier identifiant, le premier identifiant étant utilisé pour indiquer un canal logique ou programmer un premier canal de transmission, et le domaine dans lequel le premier identifiant est situé comprenant N bits, N étant un nombre entier supérieur à 6 si le premier identifiant est utilisé pour indiquer un canal logique, ou N étant un nombre entier supérieur à 16 si le premier identifiant est utilisé pour programmer un premier canal de transmission ; et envoyer des données sur le canal logique indiqué par le premier identifiant ou sur le premier canal de transmission programmé par le premier identifiant. Le procédé décrit peut être appliqué à un scénario dans lequel les données sont transmises entre un UE et un dispositif de réseau d'accès.
