Abstract

Les modes de réalisation de la présente invention concernent un procédé de transmission et de réception de données, un équipement d'utilisateur et une station de base. Le procédé consiste à : recevoir des paramètres de décalage de puissance d'un flux primaire et d'un flux secondaire et des informations d'autorisation envoyés d'une station de base ; ajuster une valeur d'autorisation de service en fonction des informations d'autorisation ; déterminer une taille de bloc de données autorisée du flux secondaire en fonction des paramètres de décalage de puissance du flux primaire et du flux secondaire et de la valeur d'autorisation de service ; effectuer un remplissage de données sur un bloc de transport du flux secondaire en fonction de la taille de bloc de données autorisée du flux secondaire ; et déterminer une taille de bloc de transport du flux secondaire après le remplissage de données et envoyer le bloc de transport du flux secondaire. Le procédé de transmission de données selon les modes de réalisation de la présente invention offre une solution efficace quant à la manière de choisir des données transportées dans le flux secondaire et de remplir les données choisies dans le flux secondaire pendant le processus de transport à deux flux.
