Abstract

L'invention concerne un procédé de transmission de données de liaison montante, un terminal, un dispositif côté réseau et un système. Le procédé consiste : à transmettre, par un terminal, des données de liaison montante, les données de liaison montante comprenant une pluralité de paquets de données; la pluralité de paquets de données étant divisés en au moins un groupe de paquets de données selon une séquence temporelle de planification; des données dans chaque groupe de paquets de données provenant du même flux de qualité de service (flux QoS); le premier paquet de données dans chaque groupe de paquets de données transportant un identifiant (ID) de flux QoS du flux QoS correspondant; et des paquets de données, autres que le premier paquet de données, dans chaque groupe de paquets de données ne transportant pas des ID de flux QoS. Les modes de réalisation de la présente invention sont avantageux pour réduire le surdébit d'un ID de flux QoS de données de liaison montante et améliorer l'efficacité de transmission des données de liaison montante.
