Abstract

La présente invention concerne un procédé de transmission de données, un dispositif terminal et un dispositif de réseau. Le procédé comprend les étapes suivantes : un dispositif de réseau envoie des premières informations de configuration à un dispositif terminal, les premières informations de configuration étant utilisées pour configurer N ensembles de ressources de signal de référence ; le dispositif terminal reçoit un signal de référence envoyé par le dispositif de réseau au moyen d'une ressource de signal de référence dans les N ensembles de ressources de signal de référence ; après avoir déterminé les informations de qualité de canal signalées et/ou le nombre de bits des informations de qualité de canal signalées, selon les premières informations de configuration et les informations de qualité de canal obtenues au moyen d'une mesure dans L unités de temps de référence, le dispositif terminal envoie les informations de qualité de canal obtenues en mesurant le signal de référence. Le procédé, le dispositif terminal et le dispositif réseau des modes de réalisation de la présente invention permettent de réduire le surdébit de signalement du dispositif terminal.
