Abstract:
(EN) A method and apparatus for transmitting a wakeup packet in a wireless LAN system is proposed. Specifically, a transmission apparatus configures a wakeup packet to which an OOK scheme is applied, and transmits the wakeup packet to a reception apparatus. The wakeup packet includes a wakeup preamble and a wakeup payload. The wakeup preamble includes a preamble sequence comprising an "on" signal and an "off" signal. The "on" signal is transmitted through an "on" symbol generated by applying a first sequence to 13 consecutive subcarriers over a 20-MHz band and performing 64-point IFFT. Information on the data rate of the wakeup payload is indicated using the preamble sequence.
(FR) L'invention concerne un procédé et un appareil de transmission d'un paquet de réveil dans un système LAN sans fil. De façon spécifique, un appareil de transmission configure un paquet de réveil auquel un schéma OOK est appliqué, et transmet le paquet de réveil à un appareil de réception. Le paquet de réveil comprend un préambule de réveil et une charge utile de réveil. Le préambule de réveil comprend une séquence de préambule comprenant un signal « Marche » et un signal « Arrêt ». Le signal « Marche » est transmis par l'intermédiaire d'un symbole « Marche » généré par application d'une première séquence à 13 sous-porteuses consécutives sur une bande de 20 MHz et réalisation d'une IFFT à 64 points. Des informations sur le débit de données de la charge utile de réveil sont indiquées à l'aide de la séquence de préambule.
(KO) 무선랜 시스템에 웨이크업 패킷을 송신하는 방법 및 장치가 제안된다. 구체적으로, 송신장치는 OOK 방식이 적용되는 웨이크업 패킷을 구성하고, 웨이크업 패킷을 수신장치로 송신한다. 웨이크업 패킷은 웨이크업 프리앰블 및 웨이크업 페이로드를 포함한다. 웨이크업 프리앰블은 온 신호와 오프 신호로 구성되는 프리앰블 시퀀스를 포함한다. 온 신호는 20MHz 대역의 연속된 13개의 서브캐리어에 제1 시퀀스를 적용하고 64-point IFFT를 수행하여 생성된 온 심벌을 통해 전달된다. 웨이크업 페이로드의 데이터 레이트에 대한 정보는 상기 프리앰블 시퀀스를 이용하여 지시된다.
