Abstract:
(EN) In a method for supporting a short transmission time interval (sTTI) in a wireless communication system according to one embodiment of the present invention, the method is performed by a terminal, and comprises the steps of: receiving a reference signal for decoding a downlink channel; and decoding the downlink channel by using the reference signal for decoding the downlink channel, wherein the reference signal for decoding the downlink channel may be transmitted by using a pattern to which a frequency separation is applied, in the case of collision with a cell-specific reference signal.
(FR) L'invention concerne, selon un mode de réalisation, un procédé qui permet de prendre en charge un intervalle de temps de transmission (sTTI) court dans un système de communication sans fil, le procédé étant exécuté par un terminal et consistant: à recevoir un signal de référence pour décoder un canal de liaison descendante ; à décoder le canal de liaison descendante à l'aide du signal de référence pour décoder le canal de liaison descendante, le signal de référence pour décoder le canal de liaison descendante pouvant être émis à l'aide d'un motif auquel une séparation de fréquence est appliquée, en cas de collision avec un signal de référence spécifique à une cellule.
(KO) 본 발명의 일 실시예에 따른 무선 통신 시스템에서 짧은 전송 시간 간격(short transmission time interval; sTTI)을 지원하는 방법에 있어서, 상기 방법은 단말에 의해 수행되고, 하향링크 채널을 복호하기 위한 참조 신호를 수신하는 단계; 및 상기 하향링크 채널을 복호하기 위한 참조 신호를 이용하여 상기 하향링크 채널을 복호하는 단계를 포함하고, 상기 하향링크 채널을 복호하기 위한 참조 신호는 셀-특정 참조 신호와 충돌하는 경우 주파수 이격이 적용된 패턴을 사용하여 전송될 수 있다.
