Abstract

L'invention concerne un procédé pour une transmission de données, une station de base et un équipement utilisateur. Le procédé consiste : à transmettre des informations d'indication de ressource à un équipement utilisateur, les informations d'indication de ressource étant utilisées pour indiquer une ressource de transmission cible entre une station de base et l'équipement utilisateur, la ressource de transmission cible étant l'une d'une pluralité de ressources de transmission, la ressource de transmission minimale de la pluralité de ressources de transmission étant inférieure à un bloc de ressource physique (PRB) ; et à réaliser, par la station de base, une transmission de données avec l'équipement utilisateur sur la base de la ressource de transmission cible. Les modes de réalisation de la présente invention peuvent réduire le gaspillage de ressources, permettant ainsi d'améliorer les performances de réseau.
