Abstract
(EN) A method and an apparatus for receiving a PPDU in a wireless LAN system are proposed. Specifically, a receiving STA receives the PPDU from a transmitting STA through an 80 MHz band, and decodes the PPDU. The PPDU includes a preamble and a data field. The 80 MHz band includes first and second 484 tone RUs. The data field includes first data for the first 484 tone RU and second data for the second 484 tone RU. The second data is data obtained by duplicating the first data. The first and second 484 tone RUs are resource units including 484 tones.
(FR) L'invention concerne un procédé et un appareil de réception d'une PPDU dans un système WLAN. Plus particulièrement, une STA de réception reçoit une PPDU en provenance d’une STA de transmission par l’intermédiaire d'une bande de 80 MHz, et décode la PPDU. La PPDU comprend un préambule et un champ de données. La bande de 80 MHz comprend des premier et second RU à 484 sous-porteuses. Le champ de données comprend des premières données pour la première RU à 484 sous-porteuses et des secondes données pour la seconde RU à 484 sous-porteuses. Les secondes données sont des données obtenues par duplication des premières données. Les première et seconde RU à 484 sous-porteuses sont des unités de ressources comprenant 484 sous-porteuses.
(KO) 무선랜 시스템에서 PPDU를 수신하는 방법 및 장치가 제안된다. 구체적으로, 수신 STA은 송신 STA으로부터 80MHz 대역을 통해 PPDU를 수신하고, PPDU를 복호한다. PPDU는 프리앰블 및 데이터 필드를 포함한다. 80MHz 대역은 제1 및 제2 484톤 RU를 포함한다. 데이터 필드는 제1 484톤 RU에 대한 제1 데이터 및 제2 484톤 RU에 대한 제2 데이터를 포함한다. 제2 데이터는 제1 데이터를 복제한 데이터이다. 제1 및 제2 484톤 RU는 484개의 톤을 포함하는 자원 유닛이다.
