Title (EN) METHOD FOR RECEIVING DOWNLINK SIGNAL BY TERMINAL IN WIRELESS COMMUNICATION SYSTEM, AND DEVICE THEREFOR
(FR) PROCÉDÉ DE RÉCEPTION D'UN SIGNAL DE LIAISON DESCENDANTE PAR UN TERMINAL DANS UN SYSTÈME DE COMMUNICATION SANS FIL, ET DISPOSITIF À CET EFFET

Abstract:
(EN) Disclosed herein is a method for transmitting a signal to or receiving a signal from a base station by a terminal in a wireless communication system. Specifically, the method comprises the steps of: receiving a first packet from the base station; transmitting, to the base station, a negative-ACK (NACK) response to the first packet; receiving a second packet from the base station and determining whether an error has occurred in the NACK response to the first packet; and transmitting, to the base station, information on whether an error has occurred in the NACK response to the first packet.
(FR) L'invention concerne un procédé pour émettre un signal à une station de base ou recevoir un signal de la part d'une station de base par un terminal dans un système de communication sans fil. Plus précisément, le procédé comprend les étapes suivantes : réception d'un premier paquet de la part de la station de base ; émission, à la station de base, d'une réponse avec accusé de réception négatif (NACK) au premier paquet ; réception d'un deuxième paquet de la part de la station de base et détermination si une erreur s'est produite dans la réponse NACK au premier paquet ; et émission, à la station de base, d'informations à propos de la survenance ou non d'une erreur dans la réponse NACK au premier paquet.
(KO) 본 출원에서는 무선 통신 시스템에서 단말이 기지국과 신호를 송수신하는 방법이 개시된다. 구체적으로, 상기 방법은, 상기 기지국으로부터 제 1 패킷을 수신하는 단계; 상기 제 1 패킷에 대한 NACK (Negative-ACK) 응답을 상기 기지국으로 송신하는 단계; 상기 기지국으로부터 제 2 패킷을 수신하여, 상기 제 1 패킷에 대한 NACK 응답의 오류 발생 여부를 판단하는 단계; 및 상기 기지국으로, 상기 제 1 패킷에 대한 NACK 응답의 오류 발생 여부 정보를 송신하는 단계를 포함하는 것을 특징으로 한다.
