Abstract
(EN) The present invention relates to a wireless communication system and, more particularly, to a method and an apparatus therefor, the method comprising the steps of: identifying a minimum storing area per data in a HARQ buffer on the basis of a TTI length; storing data for transmission of a wireless signal in the HARQ buffer on the basis of the minimum storing area per data; and transmitting the data in the HARQ buffer during a first TTI, wherein, when the data is retransmitted data, the minimum storing area per data is based on the length of a second TTI used for initial transmission of the data, and the length of the second TTI is different from the length of the first TTI.
(FR) La présente invention concerne un système de communication sans fil et, plus particulièrement, un procédé et un appareil associé, le procédé comprenant les étapes consistant à : identifier une zone de stockage minimale par données dans une mémoire tampon HARQ sur la base d'une longueur de TTI ; stocker des données pour la transmission d'un signal sans fil dans la mémoire tampon HARQ sur la base de la zone de stockage minimale par données ; et transmettre les données dans la mémoire tampon HARQ pendant un premier TTI, dans lequel, lorsque les données sont des données retransmises, la zone de stockage minimale par données est basée sur la longueur d'un second TTI utilisé pour la transmission initiale des données, et la longueur du second TTI est différente de la longueur du premier TTI.
(KO) 본 발명은 무선 통신 시스템에 관한 것으로서, 구체적으로 TTI 길이에 기반해 HARQ 버퍼에서 데이터 별 최소 저장 공간을 확인하는 단계; 상기 데이터 별 최소 저장 공간에 기반하여 상기 HARQ 버퍼에 상기 무선 신호의 전송을 위한 데이터를 저장하는 단계; 및 상기 HARQ 버퍼 내의 데이터를 제1 TTI 동안 전송하는 단계를 포함하고, 상기 데이터가 재전송 데이터인 경우, 상기 데이터 별 최소 저장 공간은 상기 데이터의 초기 전송에 사용된 제2 TTI의 길이에 기반하며, 상기 제2 TTI의 길이는 상기 제1 TTI의 길이와 상이한 방법 및 이를 위한 장치에 관한 것이다.
