Abstract

L'invention concerne un procédé et un appareil de transmission d'informations de planification. Selon la présente invention, un dispositif de réseau détermine la quantité d'informations de planification concernant un terminal, et utilise la ressource de fréquence de planification pour envoyer les informations de planification en fonction de la quantité d'informations de planification déterminée, les informations de planification étant situées au niveau d'un canal physique de commande de liaison descendante pour indiquer une ressource de canal de données d'une ressource de fréquence planifiée sur la ressource de fréquence de planification, les informations de planification étant des DCI ou un domaine d'informations dans les DCI, et la quantité d'informations de planification étant inférieure ou égale à la valeur maximale de la quantité d'informations de planification, ou étant déterminée en fonction de la longueur unitaire de domaine temporel de la ressource de fréquence planifiée et de la longueur unitaire de domaine temporel de la ressource de fréquence de planification, ou étant déterminée en fonction d'un intervalle de sous-porteuse de la ressource de fréquence planifiée, d'un intervalle de sous-porteuse de la ressource de fréquence de planification et d'une première valeur prédéfinie, ou étant déterminée en fonction de la longueur unitaire temporelle de la ressource de fréquence planifiée et de la longueur unitaire temporelle de la ressource de fréquence de planification et de la première valeur prédéfinie, et la première valeur prédéfinie étant utilisée pour déterminer la quantité de l'unité de domaine temporel maximale qui peut être planifiée par les informations de planification. La présente invention vise à réduire la complexité de la planification d'une ressource de fréquence.
