Abstract:
(EN) A method and a device for transmitting a wakeup packet in a wireless LAN system are suggested. Particularly, a transmission device configures a wakeup packet and transmits same to a reception device. The wakeup packet includes a sequence including first information and second information, by applying an OOK method. The first information and the second information are configured with an on-signal and an off-signal. The on-signal is transferred via a first symbol generated by applying a first sequence to K number of successive subcarriers in the 20MHz band and performing 64-point IFFT on the subcarriers. The off-signal is transferred via a second symbol generated by applying a second sequence to the K number of successive subcarriers in the 20MHz band and performing 64-point IFFT on the subcarriers. Of the K number of subcarriers to which the first sequence is applied, a coefficient for m number of subcarriers as a unit is set to 1 or -1 for the subcarriers, and a coefficient for the remaining subcarriers is set to 0. The first information and the second information are transmitted via a third symbol configured with the first symbol and the second symbol, respectively.
(FR) L'invention concerne un procédé et un appareil de transmission d'un paquet de réveil dans un système LAN sans fil. En particulier, un dispositif de transmission configure un paquet de réveil et transmet celui-ci à un dispositif de réception. Le paquet de réveil comprend une séquence comprenant des premières et des deuxièmes informations par application d’un procédé OOK. Les premières et les deuxièmes informations sont configurées avec un signal de marche et un signal d'arrêt. Le signal de marche est transféré par le biais d’un premier symbole généré par application d’une première séquence à un nombre K de sous-porteuses successives dans la bande de 20 MHz et par réalisation d’une transformée IFFT à 64 points sur lesdites sous-porteuses. Le signal d'arrêt est transféré par l'intermédiaire d'un second symbole généré par application d'une seconde séquence au nombre K de sous-porteuses successives dans la bande de 20 MHz et par réalisation d'une transformée IFFT à 64 points sur les sous-porteuses. À partir du nombre K de sous-porteuses auxquelles la première séquence est appliquée, un coefficient pour un nombre m de sous-porteuses en tant qu'unité est fixé à 1 ou -1 pour les sous-porteuses, et un coefficient pour les sous-porteuses restantes est fixé à 0. Les premières et les deuxièmes informations sont transmises par l'intermédiaire d'un troisième symbole configuré respectivement avec le premier symbole et le deuxième symbole.
(KO) 무선랜 시스템에 웨이크업 패킷을 송신하는 방법 및 장치가 제안된다. 구체적으로, 송신장치는 웨이크업 패킷을 구성하고, 웨이크업 패킷을 수신장치로 송신한다. 웨이크업 패킷은 OOK 방식이 적용되어 제1 정보와 제2 정보로 구성되는 시퀀스를 포함한다. 제1 정보 및 제2 정보는 온 신호와 오프 신호로 구성된다. 온 신호는 20MHz 대역의 연속된 K개의 서브캐리어에 제1 시퀀스를 적용하고 64-point IFFT를 수행하여 생성된 제1 심벌을 통해 전달된다. 오프 신호는 20MHz 대역의 연속된 K개의 서브캐리어에 제2 시퀀스를 적용하고 64-point IFFT를 수행하여 생성된 제2 심벌을 통해 전달된다. 제1 시퀀스가 적용되는 K개의 서브캐리어에서, m개의 서브캐리어 단위로 서브캐리어의 계수(coefficient)가 1 또는 -1로 설정되고 나머지 서브캐리어의 계수는 0으로 설정된다. 제1 정보 및 제2 정보 각각은 제1 심벌과 제2 심벌로 구성된 제3 심벌을 통해 송신된다.
