Abstract

La présente invention concerne un procédé de transmission de demande de planification approprié pour un équipement utilisateur. Le procédé consiste : à déterminer si une première ressource temps-fréquence d'un canal physique de commande sur la liaison montante, permettant de transmettre une demande de planification, de l'équipement utilisateur et une seconde ressource temps-fréquence d'un canal partagé sur la liaison montante, permettant de transmettre des données, de l'équipement utilisateur se chevauchent dans un domaine temporel ; et si un chevauchement existe, à transmettre la demande de planification par l'intermédiaire de la seconde ressource temps-fréquence. Selon des modes de réalisation de la présente invention, lorsqu'il est déterminé qu'une première ressource temps-fréquence d'un canal physique de commande sur la liaison montante, permettant de transmettre une demande de planification, d'un équipement utilisateur et qu'une seconde ressource temps-fréquence d'un canal partagé sur la liaison montante, permettant de transmettre des données, de l'équipement utilisateur se chevauchent dans un domaine temporel, la demande de planification peut être transmise par l'intermédiaire de la seconde ressource temps-fréquence du canal physique de commande sur la liaison montante, ce qui permet d'obtenir une ressource de liaison montante par l'intermédiaire de la demande de planification dès que possible afin de transmettre un rapport d'état de mise en cache, et de garantir une exigence d'un retard temporel relativement faible pour un premier service.
