Abstract
(EN)
The present invention relates to a method and an apparatus for transmitting an acknowledgement/negative-acknowledgement (ACK/NACK) of a terminal in a wireless communication system. More specifically, the method comprises the steps of: receiving a wide area network (WAN)-based downlink signal; and transmitting the ACK/NACK in accordance with first hybrid automatic repeat request (HARQ) processes, based on third wireless resources except for at least one second wireless resource for device-to-device (D2D) among first wireless resources for WAN communication, wherein the HARQ processes are characterized in that WAN uplink transmission timing on the second wireless resource is set up to be shifted to the third wireless resource.
(FR)
L'invention concerne un procédé et un appareil de transmission d'un signal d'accusé de réception/accusé de réception négatif (ACK/NACK) d'un terminal, dans un système de communications sans fil. Le procédé selon l'invention comprend les étapes consistant à : recevoir un signal de liaison descendante basé sur un réseau étendu (WAN) ; et transmettre le signal ACK/NACK selon des premiers processus de requête automatique de répétition hybride (HARQ) d’après des troisièmes ressources sans fil à l'exception d'au moins une deuxième ressource sans fil pour une communication de dispositif à dispositif (D2D) parmi des premières ressources sans fil pour une communication WAN. Les processus HARQ sont caractérisés en ce que l’heure de transmission en liaison montante dans le réseau WAN sur la deuxième ressource sans fil est définie de sorte à être décalée à la troisième ressource sans fil.

본 발명은 무선 통신 시스템에서 단말의 ACK/NACK(Acknowledgement/Negative-Acknowledgement) 송신 방법 및 장치에 관한 것이다. 구체적으로, WAN(Wide Area Network) 기반 하향링크 신호를 수신하는 단계 및 WAN 통신을 위한 제 1 무선 자원들 중에서 D2D(Device-to-Device)을 위한 적어도 하나의 제 2 무선 자원을 제외한 제 3 무선 자원들에 기반한, 제 1 HARQ(hybrid automatic repeat request) 프로세스들에 따라 ACK/NACK을 송신하는 단계를 포함하며, HARQ 프로세스는, 제 2 무선 자원 상의 WAN 상향링크 송신 타이밍이, 상기 제 3 무선 자원으로 시프트(shift)되도록 설정된 것을 특징으로 한다.
