Abstract:
(EN) A method for receiving, by an STA, a WUR PPDU in a WLAN, according to one embodiment of the present invention, comprises the steps of: receiving a WUR PPDU including a WUR preamble and a payload; determining whether the WUR PPDU has been received from a basic service set (BSS) to which the STA belongs or from an overlapping BSS (OBSS), on the basis of the WUR preamble; and decoding the payload of the WUR PPDU if the WUR PPDU has been received from the BSS to which the STA belongs, wherein the STA can determine whether the WUR PPDU has been received from the BSS to which the STA belongs, through a cross correlation between a synchronization sequence included in the WUR preamble and a predetermined sequence known to the STA.
(FR) L'invention concerne, selon un mode de réalisation, un procédé de réception, par une STA, d'une PPDU de WUR dans un WLAN, qui comprend les étapes consistant : à recevoir une PPDU de WUR comprenant un préambule de WUR et des données utiles; à déterminer si la PPDU de WUR a été reçue d'un ensemble de services de base (BSS) auquel la STA appartient ou d'un BSS se chevauchant (OBSS), sur la base du préambule de WUR; et à décoder les données utiles de la PPDU de WUR si la PPDU de WUR a été reçue du BSS auquel la STA appartient, la STA pouvant déterminer si la PPDU de WUR a été reçue du BSS auquel la STA appartient, par l'intermédiaire d'une corrélation croisée entre une séquence de synchronisation incluse dans le préambule de WUR et une séquence prédéterminée connue de la STA.
(KO) 본 발명의 일 실시예에 따른 WLAN에서 STA이 WUR PPDU를 수신하는 방법은, WUR 프리앰블 및 페이로드를 포함하는 WUR PPDU를 수신하는 단계; 상기 WUR 프리앰블에 기초하여 상기 WUR PPDU가 상기 STA이 속한 BSS(basic service set)로부터 수신된 것인지 아니면 OBSS(overlapping BSS)로부터 수신된 것인지 여부를 판단하는 단계; 및 상기 WUR PPDU가 상기 STA이 속한 BSS로부터 수신된 것이면 상기 WUR PPDU의 페이로드를 디코딩하는 단계를 포함하고, 상기 STA은 상기 WUR 프리앰블에 포함된 동기 시퀀스와 상기 STA에게 알려진 소정의 시퀀스 간의 교차 상관을 통해 상기 WUR PPDU가 상기 STA이 속한 BSS로부터 수신된 것인지 여부를 판단할 수 있다.
