Abstract

Les modes de réalisation de la présente invention concernent un procédé de traitement d'informations et un dispositif de communication. Le procédé de traitement d'informations comprend les étapes au cours desquelles : un premier dispositif de communication reçoit des premières informations envoyées par un second dispositif de communication, les premières informations étant utilisées pour indiquer des modes de transmission d'un premier ensemble de blocs de transmission et d'un second ensemble de blocs de transmission, le premier ensemble de blocs de transmission contenant un ou plusieurs blocs de transmission et le second ensemble de blocs de transmission contenant un ou plusieurs blocs de transmission ; le premier dispositif de communication détermine en fonction des premières informations que les données restantes dans le premier ensemble de blocs de transmission doivent être rejetées, les données restantes dans le premier ensemble de blocs de transmission étant un bloc de transmission devant être transmis dans le premier ensemble de blocs de transmission ; et le premier dispositif de communication détermine en fonction des premières informations de transmettre les données restantes dans le second ensemble de blocs de transmission pendant une première période de temps, la première période de temps comportant une période de temps restante lors du rejet des données restantes dans le premier ensemble de blocs de transmission et les données restantes dans le second ensemble de blocs de transmission étant un bloc de transmission devant être transmis dans le second ensemble de blocs de transmission.
