Abstract

Des modes de réalisation de la présente demande concernent un procédé et un dispositif de détermination de ressources de planification. Lorsqu'une pluralité de PDCCH sont configurés pour planifier la même ressource de planification cible, des décalages de créneau temporel initiaux de la ressource de planification cible par rapport aux PDCCH et des informations de configuration de la ressource de planification cible sont envoyés à un terminal au moyen d'une signalisation de couche supérieure, et des décalages de créneau temporel supplémentaires de la ressource de planification cible par rapport aux PDCCH sont envoyés au terminal au moyen d'informations d'indication, de telle sorte que le terminal détermine la ressource de planification cible conjointement en fonction des décalages de créneau temporel initiaux de la ressource de planification cible par rapport aux PDCCH, des informations de configuration de la ressource de planification cible, et des décalages de créneau temporel supplémentaires de la ressource de planification cible par rapport aux PDCCH, de telle sorte que la pluralité de PDCCH planifient la même ressource de planification cible. De plus, en indiquant, au moyen d'une signalisation de couche supérieure, des décalages de créneau temporel initiaux d'une ressource de planification cible par rapport à des PDCCH et des informations de configuration de la ressource de planification cible à un terminal, les surdébits de signalisation de couche supérieure peuvent être efficacement réduits.
