Abstract
(EN)
A method and device for transmitting an NGV frame in a wireless LAN system is proposed. Specifically, a transmission device generates an NGV frame and transmits the NGV frame through a first band. The NGV frame includes an L-STF, an L-LTF, an L-SIG, an NGV-SIG, an NGV-STF, an NGV-LTF, and NGV-Data. The L-STF, the L-LTF, the L-SIG, and the NGV-SIG are duplicated in units of second bands and transmitted through the first band. The NGV-STF, the NGV-LTF, and the NGV-Data are transmitted through a full band of the first band. The first band is a 20 MHz band, and a second band is a 10 MHz band.

La présente invention concerne un dispositif et un procédé de transmission d'une trame NGV dans un système LAN sans fil. Plus particulièrement, un dispositif de transmission qui génère une trame NGV et la transmet par l'intermédiaire d'une première bande. La trame NGV comprend un L-STF, un L-LTF, un L-SIG, un NGV-SIG, un NGV-STF, un NGV-LTF et des données NGV. Le L-STF, le L-LTF, le L-SIG et le NGV-SIG sont dupliqués dans des unités de secondes bandes et transmis à travers la première bande. Le NGV-STF, le NGV-LTF et les données NGV sont transmis à travers une bande complète de la première bande. La première bande est une bande de 20 MHz, et une seconde bande est une bande de 10 MHz.

무선랜 시스템에서 NGV 프레임을 송신하는 방법 및 장치가 제안된다. 구체적으로, 송신장치는 NGV 프레임을 생성하고, NGV 프레임을 제1 대역을 통해 송신한다. NGV 프레임은 L-STF, L-LTF, L-SIG, NGV-SIG, NGV-STF, NGV-LTF 및 NGV-Data를 포함한다. L-STF, L-LTF, L-SIG 및 NGV-SIG는 제2 대역 단위로 복제되어 제1 대역을 통해 송신된다. NGV-STF, NGV-LTF 및 NGV-Data는 제1 대역의 풀 대역을 통해 송신된다. 제1 대역은 20MHz 대역이고, 제2 대역은 10MHz 대역이다.
