Abstract

Un procédé et un appareil de transmission de liaison montante sont divulgués. Le procédé fait appel aux étapes suivantes : un dispositif de réseau envoyant, à un dispositif terminal, des informations d'indication qui indiquent des ressources préemptées, les ressources préemptées chevauchant des ressources de transmission pour une transmission de liaison montante ; le dispositif terminal mettant ensuite en mémoire cache des données codées de la transmission de liaison montante dans une première unité de temps, la première unité de temps comprenant au moins un premier symbole ; après réception de la transmission de liaison montante envoyée par le dispositif terminal, le dispositif de réseau effectuant une démodulation et un décodage ; cependant, étant donné que le dispositif de réseau peut échouer à effectuer avec succès une démodulation et un décodage, le dispositif de réseau déterminant s'il faut planifier et transmettre les données codées dans la première unité de temps mises en mémoire cache par le dispositif terminal. Au moyen du procédé, la flexibilité de transmission peut être améliorée ; et un dispositif de réseau planifie et transmet un plus petit volume de données, et ainsi moins de ressources temps-fréquence sont occupées, ce qui permet d'abaisser la consommation d'énergie d'un dispositif terminal et de réduire le retard.
