Abstract:
(EN) Presented are a method and device for transmitting a wakeup packet in a wireless LAN system. Specifically, the transmission device configures a first wakeup packet having a first data rate by using a first sync field, and a second wakeup packet having a second data rate by using a second sync field. The transmission device transmits the first and second wakeup packets to a receiving device. Here, an OOK scheme is applied to the first and second wakeup packets to configure the first and second wakeup packets as an ON signal or an OFF signal. The first sync field includes a first sequence, and the second sync field includes a second sequence which is a complementary sequence to the first sequence. The number of coefficient 1 and coefficient 0 included in the first sequence is the same. The first and second sequences have a 32 bit length, and each bit of the first and second sequences has a duration of 2 µs.
(FR) La présente invention concerne un procédé et un dispositif de transmission d'un paquet de réveil dans un système LAN sans fil. Spécifiquement, le dispositif de transmission configure un premier paquet de réveil ayant un premier débit de données à l'aide d'un premier champ de synchronisation, et un second paquet de réveil ayant un second débit de données à l'aide d'un second champ de synchronisation. Le dispositif de transmission transmet les premier et second paquets de réveil à un dispositif de réception. Ici, un un procédé OOK ("modulation par tout ou rien") est appliqué aux premier et second paquets de réveil pour configurer les premier et second paquets de réveil sous la forme d'un signal MARCHE ou d'un signal ARRÊT. Le premier champ de synchronisation comprend une première séquence, et le second champ de synchronisation comprend une seconde séquence qui est une séquence complémentaire à la première séquence. Le nombre de coefficient 1 et de coefficient 0 inclus dans la première séquence est le même. Les première et seconde séquences ont une longueur de 32 bits, et chaque bit des première et seconde séquences a une durée de 2 µs.
(KO) 무선랜 시스템에 웨이크업 패킷을 송신하는 방법 및 장치가 제안된다. 구체적으로, 송신장치는 제1 싱크 필드를 사용하여 제1 데이터 레이트를 가지는 제1 웨이크업 패킷 및 제2 싱크 필드를 사용하여 제2 데이터 레이트를 가지는 제2 웨이크업 패킷을 구성한다. 송신장치는 제1 및 제2 웨이크업 패킷을 수신장치로 송신한다. 이때, 제1 및 제2 웨이크업 패킷은 OOK 방식이 적용되어 온 신호 또는 오프 신호로 구성된다. 제1 싱크 필드는 제1 시퀀스를 포함하고, 제2 싱크 필드는 제1 시퀀스의 상보 시퀀스인 제2 시퀀스를 포함한다. 제1 시퀀스에 포함된 계수 1과 계수 0은 같은 개수이다. 제1 및 제2 시퀀스는 32비트의 길이를 가지고, 제1 및 제2 시퀀스의 각 비트는 2us의 듀레이션을 가진다.
