Abstract

Les modes de réalisation de la présente invention concernent un procédé de traitement de données et un dispositif associé, destinés à être utilisés dans un dispositif de communication, le procédé consistant à : si les ressources dans une période de trame ne sont pas utilisées pour une transmission de données d'utilisateur et que les ressources dans la période de trame comprennent des ressources préconfigurées utilisées pour une transmission de signal et/ou de canal périodique, transmettre alors le signal et/ou le canal périodique sur les ressources préconfigurées ou abandonner la transmission du signal et/ou du canal périodique sur les ressources préconfigurées. L'utilisation des modes de réalisation de l'invention permet d'améliorer le taux d'utilisation de ressources.
