Abstract
(EN)
The present invention relates to a wireless communication system, and more particularly, to a method and device for transmitting and receiving a downlink control channel for controlling inter-cell interference in a wireless communication system. An embodiment of the present invention provides a method for transmitting a downlink control channel from a base station to a terminal, and the method may comprise: a step of determining whether a downlink subframe is of a first type or a second type; and a step in which if the downlink subframe is of the first type, the number of OFDM symbols for transmitting the downlink control channel is set to a preset value (N), and the downlink control channel is transmitted using N OFDM symbols.

L'invention concerne un système de communication sans fil et, plus particulièrement, un procédé et un dispositif de transmission et de réception d'un canal de commande de liaison descendante en vue de limiter l'interférence intercellulaire dans un système de communication sans fil. Un mode réalisation de l'invention concerne un procédé de transmission d'un canal de commande de liaison descendante d'une station de base à un terminal, le procédé pouvant comprenant les étapes consistant à : établir si une sous-trame de liaison descendante est d'un premier type ou d'un deuxième type ; et, si la sous-trame de liaison descendante est du premier type, donner une valeur prédéfinie (N) au nombre de symboles OFDM pour la transmission du canal de commande de liaison descendante, et transmettre le canal de commande de liaison descendante en utilisant N symboles OFDM.
