Abstract:
(EN) A method by which an access point (AP) transmits a wake-up radio (WUR) signal in a wireless LAN (WLAN), according to one embodiment of the present invention, comprises the steps of: determining a synchronization signal providing time synchronization for a data signal in the WUR signal; and transmitting the WUR signal including the synchronization signal and the data signal, wherein the synchronization signal can be an on-off keying (OOK) signal having a length of 128 us and generated by mapping, to 2 us symbol, each bit of a binary sequence having a length of 64, when a data rate of the data signal is 62.5 kbps.
(FR) Un mode de réalisation de l’invention concerne un procédé par lequel un point d'accès (AP) transmet un signal radio de réveil (WUR) dans un LAN sans fil (WLAN). Le procédé comprend les étapes consistant à : déterminer un signal de synchronisation fournissant une synchronisation temporelle pour un signal de données dans le signal WUR ; et transmettre le signal WUR contenant le signal de synchronisation et le signal de données, le signal de synchronisation pouvant être un signal de modulation par tout ou rien (OOK) ayant une longueur de 128 us et généré par mappage sur un symbole de 2 us, chaque bit d'une séquence binaire ayant une longueur de 64, lorsqu'un débit de données du signal de données est de 62,5 kbps.
(KO) 본 발명의 일 실시예에 따른 무선 랜(WLAN)에서 엑세스 포인트(AP)가 WUR(wake-up radio) 신호를 송신하는 방법은, 상기 WUR 신호의 데이터 신호에 대한 시간 동기를 제공하는 동기 신호를 결정하는 단계; 및 상기 동기 신호 및 상기 데이터 신호를 포함하는 상기 WUR 신호를 송신하는 단계를 포함하고, 상기 데이터 신호의 데이터 레이트가 62.5kbps일 때, 상기 동기 신호는 길이 64의 이진 시퀀스의 각 비트를 2 us 심볼에 맵핑하여 생성되는 128 us 길이의 OOK(on-off keying) 신호일 수 있다.
