Abstract
(EN)
The present invention relates to a method and device for transmitting and receiving data in a wireless communication system. Specifically, the method comprises: a step in which a relay node receives a relay physical downlink control channel (R-PDCCH) including indication information relating to at least one piece of information about a second antenna port and a second scramble ID from a base station by using information about a first antenna port and a first scramble ID; and a step in which the relay node receives a downlink data channel from the base station, wherein the downlink data channel comprises a first downlink data channel region assigned to a portion of a resource block pair to which the relay physical downlink control channel is assigned, and a second downlink data channel region assigned to the other portion of the resource block pair to which the relay physical downlink control channel is assigned, wherein the first downlink data channel region is received using the first antenna and the first scramble ID, and the second downlink data channel region is received using the indication information.

L'invention concerne un procédé et un dispositif de transmission et de réception de données dans un système de communication sans fil, le procédé comprenant plus particulièrement les étapes suivantes : réception, par un nœud relais, depuis une station de base, d'un canal de commande physique de liaison descendante relais (R-PDCCH) comprenant des informations d'indication relatives à au moins une information concernant un deuxième accès antenne et un deuxième identifiant de brouillage à partir d'informations concernant un premier accès antenne et un premier identifiant de brouillage; et réception, par le nœud relais, depuis la station de base, d'un canal de données de liaison descendante, lequel canal de données de liaison descendante comprend une première région de canal de données de liaison descendante affectée à une partie d'une paire de blocs de ressources à laquelle le canal de commande physique de liaison descendante relais est affecté, et une deuxième région de canal de données de liaison descendante affectée à l'autre partie de la paire de blocs de ressources à laquelle le canal de commande physique de liaison descendante relais est affecté. La première région de canal de données de liaison descendante est reçue au moyen du premier accès antenne et du premier identifiant de brouillage, et la deuxième région de canal de données de liaison descendante est reçue au moyen des informations d'indication.
