Abstract
(EN)
A method and a device for transmitting a broadcast frame to a wireless LAN system are presented. Particularly, a transmitting STA having a multiple BSSID generates a broadcast frame and transmits the broadcast frame to a receiving STA. The multiple BSSID includes a first BSSID and a second BSSID. The first BSSID is an identifier of a first BSS that transmits a beacon frame. The second BSSID is an identifier of a second BSS excluding the first BSS in all BSSs mapped to the multiple BSSID. The broadcast frame includes an ID field. The ID field is set to an ID for all of the BSSs. IDs for all of the BSSs are acquired on the basis of a transmission end ID for identifying the transmitting STA. The transmission ID is acquired on the basis of the first BSSID.

La présente invention concerne un procédé et un dispositif de transmission d'une trame de diffusion dans un système LAN sans fil. En particulier, une STA de transmission ayant un BSSID multiple génère une trame de diffusion et transmet la trame de diffusion à une STA de réception. Le BSSID multiple comprend un premier BSSID et un second BSSID. Le premier BSSID est un identifiant d'un premier BSS qui transmet une trame balise. Le second BSSID est un identifiant d'un second BSS excluant le premier BSS dans tous les BSS mappés sur le BSSID multiple. La trame de diffusion comprend un champ d'identifiant (ID). Le champ d'identifiant est défini comme un identifiant pour tous les BSS. Des identifiants pour tous les BSS sont acquis sur la base d'un identifiant d'extrémité de transmission pour identifier la STA de transmission. L'ID de transmission est acquis sur la base du premier BSSID.

무선랜 시스템에 브로드캐스트 프레임을 송신하는 방법 및 장치가 제안된다. 구체적으로, 다중 BSSID를 가진 송신 STA은 브로드캐스트 프레임을 생성하고, 브로드캐스트 프레임을 수신 STA에게 송신한다. 다중 BSSID는 제1 BSSID 및 제2 BSSID를 포함한다. 제1 BSSID는 비콘 프레임을 송신하는 제1 BSS의 식별자이다. 제2 BSSID는 상기 다중 BSSID에 매핑된 모든 BSS에서 제1 BSS를 제외한 제2 BSS의 식별자이다. 브로드캐스트 프레임은 ID 필드를 포함한다. ID 필드는 모든 BSS에 대한 ID로 설정된다. 모든 BSS에 대한 ID는 송신 STA을 식별하는 송신단 ID를 기반으로 획득된다. 송신단 ID는 제1 BSSID를 기반으로 획득된다.
