Abstract
(EN)
The present invention relates to a method and a device for transmitting/receiving data in a wireless communication system supporting a relay node in a wireless communication system. The method for transmitting data from a base station according to one embodiment of the present invention comprises: a step for transmitting to the relay node a signal having a first data to be delivered to a user equipment via the relay node; a step for transmitting to the user equipment a signal having a second data; and a step for receiving from the user equipment a HARQ confirmation response information regarding the first data delivered to the user equipment through the relay node, wherein the first data is retransmitted to the user equipment from the relay node when the HARQ confirmation response information is NACK, and scheduling information for transmitting the first data from the relay node to the user equipment and scheduling information for retransmitting the first data can be designated in advance by the base station.

La présente invention concerne un procédé et un dispositif pour la transmission/réception de données dans un système de communications sans fil sous lequel fonctionne un nœud relais dans un système de communications sans fil. Selon un mode de réalisation de la présente invention, le procédé pour la transmission de données depuis une station de base comprend: une étape pour la transmission au nœud relais d'un signal comprenant une première donnée à être délivrée à un équipement utilisateur d'une première donnée pour être délivrée à l'équipement utilisateur via le nœud relais ; une étape pour la transmission à l'équipement utilisateur d'un signal comprenant une seconde donnée ; et une étape pour la réception depuis l'équipement utilisateur d'une information de réponse en confirmation à une requête automatique de répétition hybride (HARQ) concernant la première donnée délivrée à l'équipement utilisateur via le nœud relais, la première donnée étant retransmise vers l'équipement utilisateur depuis le nœud relais lorsque l'information de réponse en confirmation à une requête automatique de répétition hybride (HARQ) est un accusé de réception négatif, et l'information d'ordonnancement pour la transmission de la première donnée depuis le nœud relais vers l'équipement utilisateur et l'information d'ordonnancement pour la retransmission de la première donnée peuvent être désignées à l'avance par la station de base.
