Abstract:
(EN) A method for receiving a WUR PPDU in WLAN by an STA according to an embodiment of the present invention may comprise the steps of: receiving a WUR PPDU including a WUR preamble and a payload; acquiring information on a data rate applied to the payload, on the basis of a synchronization sequence of the WUR preamble; and decoding the payload on the basis of the information on the data rate, wherein the STA determines that the data rate applied to the payload is 250 kbps when the synchronization sequence is a first sequence having a length of 32 bits, and determines that the data rate applied to the payload is 62.5 kbps when the synchronization sequence is a second sequence having a length of 64 bits.
(FR) La présente invention porte, selon un mode de réalisation, sur un procédé permettant de recevoir une unité PPDU WUR dans un réseau WLAN au moyen d'une station (STA) qui peut comprendre les étapes consistant : à recevoir une unité PPDU WUR comprenant un préambule WUR et une charge utile ; à acquérir des informations concernant un débit de données appliqué à la charge utile, sur la base d'une séquence de synchronisation du préambule WUR ; et à décoder la charge utile sur la base des informations concernant le débit de données, la station déterminant que le débit de données appliqué à la charge utile est de 250 kbps lorsque la séquence de synchronisation est une première séquence ayant une longueur de 32 bits, et déterminant que le débit de données appliqué à la charge utile est de 62,5 kbps lorsque la séquence de synchronisation est une seconde séquence ayant une longueur de 64 bits.
(KO) 본 발명의 일 실시예에 따른 WLAN에서 STA이 WUR PPDU를 수신하는 방법은, WUR 프리앰블 및 페이로드를 포함하는 WUR PPDU를 수신하는 단계; 상기 WUR 프리앰블의 동기 시퀀스에 기초하여 상기 페이로드에 적용된 데이터 레이트에 대한 정보를 획득하는 단계; 및 상기 데이터 레이트에 대한 정보에 기초하여 상기 페이로드를 디코딩하는 단계를 포함하고, 상기 STA은, 상기 동기 시퀀스가 길이 32-비트를 갖는 제1 시퀀스인 경우 상기 페이로드에 적용된 데이터 레이트가 250 kbps라고 판정하고, 상기 동기 시퀀스가 길이 64-비트를 갖는 제2 시퀀스인 경우 상기 페이로드에 적용된 데이터 레이트가 62.5 kbps라고 판정할 수 있다.
