Abstract

L'invention concerne un procédé et un dispositif de réduction de temps de latence réseau dans une communication radio. Un UE reçoit une première signalisation. La première signalisation est une signalisation de couche physique et comprend des informations de programmation de premières données. L'UE transmet les premières données sur un premier ensemble de blocs de ressources physiques (PRB) d'après la première signalisation. Le premier ensemble de PRB est l'un de K types d'ensembles de PRB candidats et comprend G sous-ensembles de PRB. L'un des sous-ensembles de PRB comprend au moins un PRB. Les G sous-ensembles de PRB comprennent un total de M PRB. Les PRB dans les sous-ensembles de PRB sont continus dans un domaine fréquentiel. En concevant un nouveau type d'attribution de ressources correspondant à un ensemble de PRB candidats, l'invention garantit la compatibilité des premières données avec un système actuel durant un processus de transmission, ce qui permet d'obtenir un gain de diversité élevé et garantit un gain de performance d'un système à faible latence globalement.
