Abstract:
(EN) A method by which an access point (AP) transmits a wake up radio (WUR) frame in a wireless LAN (WLAN) system according to one embodiment of the present invention comprises: a step for generating a WUR frame including a WUR preamble part and a control information part on the basis of an on-off keying (OOK) method; and a step for transmitting the WUR frame generated on the basis of the OOK method, wherein a last symbol among a plurality of symbols, which are included in the WUR preamble part, is set as an off symbol so as to distinguish the WUR preamble part and the control information part, and a synchronization sequence for the WUR frame can be repetitively transmitted, in a time domain, at least twice on predetermined symbols located prior to the off symbol of the WUR preamble part.
(FR) L'invention concerne un procédé par lequel un point d'accès (AP) transmet une trame de radio de réveil (WUR) dans un système LAN sans fil (WLAN) selon un mode de réalisation et comprend : une étape de génération d'une trame de WUR comprenant une partie de préambule de WUR et une partie d'informations de commande sur la base d'un procédé de modulation par tout ou rien (OOK) ; et une étape consistant à transmettre la trame de WUR générée sur la base du procédé OOK, un dernier symbole parmi une pluralité de symboles, qui sont inclus dans la partie de préambule de WUR, étant défini en tant que symbole d'arrêt de façon à distinguer la partie de préambule de WUR de la partie d'informations de commande, et une séquence de synchronisation pour la trame de WUR pouvant être transmise de manière répétitive, dans un domaine temporel, au moins deux fois sur des symboles prédéfinis situés avant le symbole d'arrêt de la partie de préambule de WUR.
(KO) 본 발명의 일 실시예에 따른 무선 랜(WLAN) 시스템에서 엑세스 포인트(AP)가 WUR(wake up radio) 프레임을 송신하는 방법은, OOK(on-off keying) 방식에 기반하여 WUR 프리앰블 파트 및 제어 정보 파트를 포함하는 WUR 프레임을 생성하는 단계; 및 상기 OOK 방식에 기반하여 생성된 상기 WUR 프레임을 송신하는 단계를 포함하되, 상기 WUR 프리앰블 파트와 상기 제어 정보 파트의 구분을 위하여 상기 WUR 프리앰블 파트에 포함된 다수의 심볼들 중 마지막 심볼은 오프(off) 심볼로 설정되고, 상기 WUR 프리앰블 파트의 상기 오프 심볼 이전에 위치한 소정의 심볼들 상에서는 상기 WUR 프레임에 대한 동기 시퀀스가 시간 도메인에서 적어도 2번 이상 반복 송신될 수 있다.
