Abstract

La présente invention concerne, dans des modes de réalisation, un procédé, un dispositif et un système de transmission de données, permettant de mettre en œuvre une transmission simultanée de données PUCCH et de données PUSCH au moyen de différents procédés de codage. Les données PUCCH et les données PUSCH d'un UE sont simultanément transmises sur un PRB adjacent, ce qui assure la faible latence de transmission en liaison montante sur le côté UE et, étant donné que le PRB utilisé pour transmettre des données PUCCH et le PRB utilisé pour transmettre des données PUSCH sont adjacents, cela réduit également efficacement l'interférence provoquée par d'autres bandes de fréquence, réduisant ainsi l'impact sur d'autres UE.
