Abstract

La présente invention concerne un dispositif et un procédé par lequel un terminal transmet un canal physique partagé montant (PUSCH) dans un système de communication sans fil. Selon la présente invention, le terminal reçoit une pluralité d'éléments d'informations de configuration pour une transmission de PUSCH basée sur une autorisation configurée, chacun des éléments d'informations de configuration comprenant des informations d'attribution de ressources pour l'attribution de chacune d'une pluralité de ressources pour une transmission de PUSCH. Ensuite, le terminal transmet le PUSCH à une station de base, à l'aide de ressources spécifiques parmi la pluralité de ressources. Les ressources spécifiques sont utilisées de manière répétée pour transmettre de manière répétée le PUSCH un nombre défini de fois pendant une période définie, la pluralité de ressources attribuées pour la transmission répétée du PUSCH pendant la période définie ayant le même identifiant de processus (ID) de requête automatique de répétition hybride (HARQ) correspondant à celui-ci, l'ID de processus de HARQ étant généré sur la base d'une valeur spécifique.
