Abstract

La présente invention concerne un procédé et un dispositif permettant de configurer une unité de temps de transmission. Le procédé de la présente invention consiste : à définir une nouvelle sous-trame de technologie d'accès radio (RAT) NRsf ; et à acquérir, conformément à la nouvelle sous-trame RAT d'agrégation de fonctions prédéfinie NRsf, une trame de planification SDF, la nouvelle sous-trame RAT NRsf étant une unité de temps programmable minimum, et la trame d'ordonnancement SDF est utilisée pour décrire des ressources de domaine temporel permettant la transmission de blocs de données. La présente invention résout le problème dans les configurations de structure existantes d'un cadre de système LTE, selon lequel des configurations fixes de structures de trame et de paramètres de trame sont adoptées et entraînent des difficultés à satisfaire aux exigences de transmission de multiples services dans une même bande de fréquence ou des bandes de fréquence différentes. De cette manière, la présente invention réussit à satisfaire aux exigences de transmission de multiples services dans une même bande de fréquence ou dans des bandes de fréquence différentes.
