Abrégé
(EN)
Disclosed are a method and an apparatus for transmitting reception acknowledgement information for an HARQ (Hybrid Automatic Repeat Request) in a wireless communication system. A terminal receives the information on downlink resource allocation through at least one downlink carrier among plural downlink carriers. In addition, the terminal receives a downlink transmission block through a downlink share channel indicated by the downlink resource allocation. The terminal transmits an ACK/NACK signal for the downlink transmission block through an uplink control channel. If at least one downlink carrier is a primary carrier, the uplink control channel uses a primary resource. Otherwise, the uplink control channel uses a secondary resource.

L'invention concerne un procédé et un appareil d'émission d'informations d'accusé de réception pour une demande de répétition automatique hybride (HARQ) sur un système de communication sans fil. Un terminal reçoit les informations sur l'affectation de ressources descendantes au moyen au moins d'une porteuse descendante parmi une pluralité de porteuses descendantes. En outre, le terminal reçoit un bloc d'émission descendante sur un canal descendant partagé indiqué par l'affectation de ressources descendantes. Le terminal envoie un signal ACK/NACK pour le bloc d'émission descendante sur un canal de commande montant. Si au moins une porteuse descendante est une porteuse primaire, le canal de commande montant utilise une ressource primaire. Sinon, le canal de commande montant utilise une ressource secondaire.
