Abstract

L'invention concerne un procédé et un dispositif d'indication et de détermination de ressources à multiples canaux qui résolvent le problème de faible flexibilité et de réponse lente en raison du fait que des informations d'indication d'IE d'une couche de contrôle d'accès au support (MAC) ont besoin d'être utilisées dans le mode d'indication de ressources à multiples canaux existant. Le procédé comprend les opérations suivantes : un dispositif de réseau configure des blocs de ressources pour un équipement utilisateur sur chaque canal unique, contenu dans de multiples canaux pouvant être utilisés par l'équipement utilisateur, et détermine des informations d'indication utilisées pour indiquer des blocs de ressources configurés sur chaque canal unique pour tous les équipements utilisateur par le dispositif de réseau ; le dispositif de réseau envoie, dans un en-tête de trame de couche physique d'une sous-trame de chaque canal unique, des informations d'indication correspondant à certains ou à l'ensemble des canaux uniques contenus dans les multiples canaux, des en-têtes de trame de couche physique de sous-trames de k canaux uniques contenant les informations d'indication correspondant à tous les canaux uniques, et des en-têtes de trame de couche physique de sous-trames de n-k canaux uniques restants contenant les informations d'indication correspondant à certains canaux uniques. En raison du fait que la présente invention emploie un procédé d'indication de couche physique pure, une configuration de ressource flexible et une réponse rapide sont obtenues.
