Abstract
(EN) The present invention relates to a wireless communication system. More particularly, the present invention relates to a method and to an apparatus for the method, wherein the method is configured such that a base station, in which cross-carrier scheduling through a first component carrier (CC) is set, transmits a downlink signal in a TDD wireless communication system in which the first CC and a second CC are aggregated, wherein the method comprises a step of transmitting a control channel signal during a specific subframe timing during which the second CC is set as a downlink. The transmitting step involves transmitting the control channel signal through a control channel region of the first CC when the first CC is set as a downlink in the specific subframe timing, and transmitting the control channel signal through a control channel region of the second CC when the first CC is set as an uplink during the specific subframe timing.
(FR) La présente invention concerne un système de communication sans fil. Plus précisément, la présente invention concerne un procédé et un appareil destiné au procédé, le procédé étant configuré de manière à ce qu'une station de base, dans laquelle une planification inter-porteuse est établie par l'intermédiaire d'une première porteuse constitutive (CC), émette un signal de liaison descendante dans un système de communication sans fil TDD dans lequel la première porteuse constitutive et une seconde porteuse constitutive sont agrégées, le procédé comprenant une étape consistant à émettre un signal de canal de commande pendant un temps de sous-trame spécifique pendant lequel la seconde porteuse constitutive est définie en tant que liaison descendante. L'étape d'émission consiste à émettre le signal de canal de commande par l'intermédiaire d'une région de canal de commande de la première porteuse constitutive lorsque la première porteuse constitutive est définie en tant que liaison descendante pendant le temps de sous-trame spécifique, et à émettre le signal de canal de commande par l'intermédiaire d'une région de canal de commande de la seconde porteuse constitutive lorsque la première porteuse constitutive est définie en tant que liaison montante pendant le temps de sous-trame spécifique.
(KO) 본 발명은 무선 통신 시스템에 관한 것이다. 구체적으로, 본 발명은 제1 컴포넌트 캐리어(CC)와 제2 CC가 병합된 TDD 무선 통신 시스템에서 상기 제1 CC를 통한 크로스-캐리어 스케줄링이 설정된 기지국이 하향링크 신호를 전송하는 방법에 있어서, 상기 제2 CC가 하향링크로 설정된 특정 서브프레임 타이밍에서 제어 채널 신호를 전송하는 단계를 포함하며, 상기 전송하는 단계는 상기 특정 서브프레임 타이밍에서 상기 제1 CC가 하향링크로 설정된 경우 상기 제1 CC의 제어 채널 영역을 통해 상기 제어 채널 신호를 전송하고, 상기 특정 서브프레임 타이밍에서 상기 제1 CC가 상향링크로 설정된 경우 상기 제2 CC의 제어 채널 영역을 통해 상기 제어 채널 신호를 전송하는 것을 포함하는 방법 및 이를 위한 장치에 관한 것이다.
