Abstract

Dans les modes de réalisation de la présente invention, il convient de définir une ressource, qui envoie des informations de non-données à un terminal, configurée pour ou associée à un paramètre de configuration de commande de liaison descendante de deux paramètres de configuration de commande de liaison descendante configurés pour le terminal pour former un sous-ensemble, associé à l'autre paramètre de configuration de commande de liaison descendante, d'une ressource indiquée par des informations d'indication d'adaptation de débit envoyées au terminal, ce qui permet d'éviter une information de données d'envoi de TRP sur une ressource où un autre TRP envoie des informations de non-données ou n'envoie pas d'informations de données. Le terminal peut effectuer une adaptation de débit en fonction d'informations d'indication d'adaptation de débit envoyées par un point d'émission et de réception, ce qui permet de démoduler correctement des données. La présente invention peut être adaptée à différents scénarios d'adaptation de débit.
