Abstract: front page image
(EN)Disclosed is a method for operating a communication node supporting a low power mode in a wireless LAN. A method for operating a station, which includes a PCR and a WURx, comprises the steps of: allowing the WURx, which operates in a wake-up state, to receive a wake-up packet from an access point; transitioning an operating state of the PCR from a sleep state to the wake-up state when the wake-up packet is received; allowing the PCR, which operates in the wake-up state, to receive a data frame from an access point; and allowing the PCR to transmit, to the access point, a response to the data frame.
(FR)L'invention concerne un procédé de commande d'un nœud de communication prenant en charge un mode de faible puissance dans un réseau local (LAN) sans fil. Un procédé de commande d'une station comprenant un PCR et un WURx, comprend les étapes consistant à : permettre au WURx, qui fonctionne dans un état de réveil, de recevoir un paquet de réveil à partir d'un point d'accès; faire passer un état de fonctionnement du PCR d'un état de sommeil à l'état de réveil lorsque le paquet de réveil est reçu; permettre au PCR, qui fonctionne dans l'état de réveil, de recevoir une trame de données à partir d'un point d'accès; et permettre au PCR de transmettre une réponse à la trame de données, au point d'accès.
(KO)무선랜에서 저전력 모드를 지원하는 통신 노드의 동작 방법이 개시된다. PCR 및 WURx를 포함하는 스테이션의 동작 방법은, 웨이크업 상태로 동작하는 상기 WURx는 액세스 포인트로부터 웨이크업 패킷을 수신하는 단계, 상기 웨이크업 패킷이 수신된 경우에 상기 PCR의 동작 상태는 슬립 상태에서 상기 웨이크업 상태로 천이하는 단계, 상기 웨이크업 상태로 동작하는 상기 PCR은 상기 액세스 포인트로부터 데이터 프레임을 수신하는 단계, 및 상기 PCR은 상기 데이터 프레임에 대한 응답을 상기 액세스 포인트에 전송하는 단계를 포함한다.
