Abstract
(EN) Disclosed is a method for transmitting or receiving a physical layer protocol data unit (PPDU) in a wireless communication system. A terminal receives, from an access point (AP), a frame indicating, to one or more terminals, transmission of the PPDU. The frame comprises a common information field and a user information field for each of the one or more terminals, and at least one of the common information field and the user information field is used to identify whether the PPDU indicated by a trigger frame corresponds to an extremely high throughput (EHT) PPDU or a high efficiency (HE) PPDU. In response to the frame, the terminal transmits the PPDU.
(FR) Est divulgué ici un procédé pour transmettre ou recevoir une unité de données de protocole de couche physique (PPDU) dans un système de communication sans fil. Un terminal reçoit, en provenance d'un point d'accès (AP), une trame indiquant, à un ou plusieurs terminaux, la transmission de la PPDU. La trame comprend un champ d'informations commun et un champ d'informations d'utilisateur pour chacun des un ou plusieurs terminaux, et le champ d'informations commun et/ou le champ d'informations d'utilisateur sont utilisés pour identifier si la PPDU indiquée par une trame de déclenchement correspond à une PPDU à débit extrêmement élevé (EHT) ou à une PPDU à haute efficacité (HE). En réponse à la trame, le terminal transmet la PPDU.
(KO) 무선 통신 시스템에서 PPDU를 송수신하는 방법이 개시된다. 단말은 AP(Access Point)로부터 하나 또는 그 이상의 단말들에게 물리 계층 프로토콜 데이터 유닛(Physical layer Protocol Data Unit: PPDU)의 전송을 지시하는 프레임을 수신한다. 상기 프레임은 공통 정보 필드(common information field) 및 상기 하나 또는 그 이상의 단말들 각각을 위한 사용자 정보 필드(user information field)를 포함하고, 상기 공통 정보 필드 및 상기 사용자 정보 필드 중 적어도 하나는 상기 트리거 프레임에 의해서 지시되는 상기 PPDU가 EHT(Extremely High Throughput) PPDU인지 또는 HE(High Efficiency) PPDU인지 여부를 식별하기 위해서 사용된다. 상기 프레임에 대한 응답으로 단말은 상기 PPDU를 전송한다.
