Abstract:
(EN) A method by which an access point (AP) transmits a physical layer protocol data unit (PPDU) in a wireless LAN (WLAN), according to one embodiment of the present invention, comprises the steps of: mapping a wake-up radio (WUR) PPDU to any one among a plurality of WUR bands included in a primary connectivity radio (PCR) band; mapping a PCR PPDU to at least one resource unit (RU) among a plurality of RUs included in the PCR band; and transmitting, on the same time resource, the WUR PPDU and the PCR PPDU which are frequency-multiplexed, wherein the AP can select, from among the remaining RUs, at least one RU to which the PCR PPDU is to be mapped, excluding, from among the plurality of RUs, the RU overlapped with the WUR band to which the WUR PPDU is mapped and the RU including guard subcarriers for the WUR PPDU.
(FR) L'invention concerne un procédé par lequel un point d'accès (AP) transmet une unité de données de protocole de couche physique (PPDU) dans un LAN sans fil (WLAN). Selon un mode de réalisation de la présente invention, le procédé comprend les étapes consistant à : mapper une PPDU de radio de réveil (WUR) sur l'une quelconque d'une pluralité de bandes WUR incluses dans une bande de radio à connectivité primaire (PCR); mapper une PPDU PCR sur au moins une unité de ressource (RU) d'une pluralité de RU incluses dans la bande PCR; et transmettre, sur la même ressource temporelle, la PPDU WUR et la PPDU PCR qui sont multiplexées en fréquence, l'AP pouvant sélectionner, parmi les RU restantes, au moins une RU sur laquelle la PPDU PCR doit être mappée, en excluant, de la pluralité de RU, la RU chevauchée par la bande WUR sur laquelle la PPDU WUR est mappée et la RU comprenant des sous-porteuses de garde pour la PPDU WUR.
(KO) 본 발명의 일 실시예에 따른 무선 랜(WLAN)에서 엑세스 포인트(AP)가 PPDU (physical layer protocol data unit)를 송신하는 방법은, PCR(primary connectivity radio) 대역에 포함된 다수의 WUR(wake-up radio) 대역 들 중 어느 하나에 WUR PPDU를 맵핑하는 단계; 상기 PCR 대역에 포함된 다수의 자원 유닛(RU)들 중 적어도 하나의 RU에 PCR PPDU를 맵핑하는 단계; 및 주파수 다중화된 상기 WUR PPDU 및 상기 PCR PPDU를 동일한 시간 자원 상에서 송신하는 단계를 포함하고, 상기 AP는 상기 다수의 RU들 중에서 상기 WUR PPDU가 맵핑되는 WUR 대역과 중첩하는 RU와 상기 WUR PPDU를 위한 가드(guard) 서브캐리어들을 포함하는 RU를 제외한 나머지 RU들 중에서 상기 PCR PPDU를 맵핑할 적어도 하나의 RU를 선택할 수 있다.
