Abstract: front page image
(EN)A method for receiving control information by a terminal in a wireless communication system according to one embodiment of the present invention may comprise the steps of: receiving a reference signal through at least one of multiple antenna ports of a base station; and blind-detecting control information of the terminal on the basis of at least one of a first transmission scheme using a single antenna port for the reference signal and a second transmission scheme using the multiple antenna ports for the reference signal, wherein a resource area for the first transmission scheme may overlap at least partially with a resource area for the second transmission scheme and, when the terminal performs blind-detection on the basis of the first transmission scheme, the terminal may perform the blind-detection on an assumption that the reference signal is transmitted according to the second transmission scheme in the overlapping resource area.
(FR)Un procédé de réception d'informations de commande par un terminal dans un système de communication sans fil selon un mode de réalisation de la présente invention peut comprendre les étapes consistant à : recevoir un signal de référence via au moins l’un d’une pluralité de ports d'antenne d'une station de base ; et détecter à l’aveugle des informations de commande du terminal sur la base d'au moins l'un d'un premier schéma de transmission utilisant un port d'antenne unique pour le signal de référence et d'un second schéma de transmission utilisant la pluralité de ports d'antenne pour le signal de référence. Une zone de ressources pour le premier schéma de transmission peut chevaucher au moins partiellement une zone de ressources pour le second schéma de transmission et, lorsque le terminal exécute une détection à l’aveugle sur la base du premier schéma de transmission, le terminal peut exécuter la détection à l’aveugle sur la base d’une hypothèse selon laquelle le signal de référence est transmis selon le second schéma de transmission dans la zone de ressources en chevauchement.
(KO)본 발명의 일 실시예에 따른 무선 통신 시스템에서 단말이 제어 정보를 수신하는 방법은, 기지국의 다수의 안테나 포트들 중 적어도 하나를 통해 참조 신호를 수신하는 단계; 및 상기 참조 신호를 위해 단일 안테나 포트가 사용되는 제1 송신 방식 및 상기 다수의 안테나 포트들이 사용되는 제2 송신 방식 중 적어도 하나에 기반하여, 상기 단말의 제어 정보에 대한 블라인드 검출을 수행하는 단계를 포함하고, 상기 제1 송신 방식을 위한 자원 영역과 상기 제2 송신 방식을 위한 자원 영역은 적어도 일부 중첩하고, 상기 단말이 상기 제1 송신 방식에 기반하여 블라인드 검출을 수행하는 경우, 상기 중첩된 자원 영역에서는 상기 제2 송신 방식에 의해 상기 참조 신호가 송신된다고 가정하고 블라인드 검출을 수행할 수 있다.
