Abstract | Proposed is a method and apparatus for transmitting a C-OFDMA PPDU in a wireless LAN system. Specifically, a first AP transmits a C-OFDMA request frame to a second AP. The first AP receives a C-OFDMA response frame as a response to the C-OFDMA request frame from the second AP. The first AP transmits a first C-OFDMA PPDU to a first STA through a first channel. A second C-OFDMA PPDU is transmitted simultaneously together with the first PPDU through a second channel by the second AP. The C-OFDMA request frame includes first information indicating that using the second channel for the second AP is allowed. The first channel corresponds to a channel remaining after excluding a preamble-punctured channel from the entire channel, and the second channel corresponds to the preamble-punctured channel.
La présente invention concerne un procédé et un dispositif de transmission d'une PPDU C-OFDMA dans un système LAN sans fil. En particulier, un premier AP transmet une trame de requête de C-OFDMA à un second AP. Le premier AP Reçoit une trame de réponse C-OFDMA en réponse à la trame de requête de C-OFDMA en provenance du second AP. Le premier AP transmet une première PPDU C-OFDMA à une première station (STA) par l'intermédiaire d'un premier canal. Une seconde PPDU C-OFDMA est transmise simultanément avec la première PPDU par l'intermédiaire d'un second canal par le second AP. La trame de requête C-OFDMA comprend des premières informations indiquant que l'utilisation du second canal pour le second AP est autorisée. Le premier canal correspond à un canal restant après l'exclusion d'un canal à préambule perforé à partir de l'ensemble du canal, et le second canal correspond au canal à préambule perforé.
무선랜 시스템에서 C-OFDMA PPDU를 전송하는 방법 및 장치가 제안된다. 구체적으로, 제1 AP는 C-OFDMA 요청 프레임을 제2 AP로 전송한다. 제1 AP는 제2 AP로부터 C-OFDMA 요청 프레임에 대한 응답으로 C-OFDMA 응답 프레임을 수신한다. 제1 AP는 제1 채널을 통해 제1 C-OFDMA PPDU를 제1 STA에게 전송한다. 제1 PPDU와 동시에 제2 AP에 의해 제2 C-OFDMA PPDU가 제2 채널을 통해 전송된다. C-OFDMA 요청 프레임은 제2 AP에 대해 제2 채널의 사용을 허용한다는 제1 정보를 포함한다. 제1 채널은 전체 채널에서 프리앰블 펑처링된 채널을 제외한 채널이고 제2 채널은 상기 프리앰블 펑처링된 채널이다. |
