Abstract
(EN)
A method and a device for transmitting a wakeup packet in a wireless LAN system are presented. Particularly, a transmission device generates a wakeup packet by applying an OOK scheme. The transmission device performs first channel sensing during a first backoff period in first and second sub-channels. The transmission device performs second channel sensing during a second backoff period in the first and second sub-channels. The transmission device transmits the wakeup packet through an 80MHz channel to a reception device after the second backoff period.

L'invention concerne un procédé et un appareil de transmission d'un paquet de réveil dans un système LAN sans fil. Plus particulièrement, un dispositif de transmission génère un paquet de réveil par application d'un procédé OOK. Le dispositif de transmission effectue une première détection de canal pendant une première période de réduction de puissance dans des premier et second sous-canaux. Le dispositif de transmission effectue une seconde détection de canal pendant une seconde période de réduction de puissance dans les premier et second sous-canaux. Le dispositif de transmission transmet le paquet de réveil par un canal de 80 MHz à un dispositif de réception après la seconde période de réduction de puissance.
(KO)
무선랜 시스템에 웨이크업 패킷을 송신하는 방법 및 장치가 제안된다. 구체적으로, 송신장치는 OOK 방식을 적용하여 웨이크업 패킷을 생성한다. 송신장치는 제1 및 제2 서브채널에서 제1 백오프 구간 동안 제1 채널 센싱을 수행한다. 송신장치는 제1 및 제2 서브채널에서 제2 백오프 구간 동안 제2 채널 센싱을 수행한다. 송신장치는 제2 백오프 구간 이후에 상기 웨이크업 패킷을 80MHz 채널을 통해 수신장치로 송신한다.
