Title (EN) WIRELESS FRAME TRANSMISSION METHOD ON BASIS OF SIGNALING FIELD SORTING OF EACH BAND AND DEVICE FOR SAME
(FR) PROCÉDÉ DE TRANSMISSION DE TRAME SANS FIL BASÉ SUR LA SIGNALISATION D'UN CLASSEMENT DE CHAMP DE CHAQUE BANDE, ET DISPOSITIF ASSOCIÉ

Abstract:
(EN) In a wireless frame transmission method by an access point (AP) in a wireless LAN system, according to an embodiment of the present invention, a wireless frame, comprising a signaling field and a data field, is generated in the AP, wherein the signaling field comprises a first signaling field (SIG A field), having first common control information about a plurality of STAs, and a second signaling field (SIG B field) having individual control information for each of the plurality of STAs. The second signaling field comprises a common field, having second common control information about the plurality of STAs, and an individual field following the common field and having individual control information for each of the STAs. An individual field (a first individual field) of the second signaling field being transmitted from a particular 20MHz band (a first band) can comprise: resource allocation information about one or more first band STAs to which resources are allocated in the first band; and resource allocation information about one or more second band STAs to which resources are allocated from another 20MHz band (a second band) other than the first band. Therefore, the length of the first individual field can be set to be the same as the length of the individual field (second individual field) of the second signaling field being transmitted from the second band.
(FR) Selon un mode de réalisation de la présente invention, dans un procédé de transmission de trame sans fil par un point d'accès (AP) dans un système LAN, une trame sans fil, contenant un champ de signalisation et un champ de données, est générée dans l'AP. Le champ de signalisation comprend un premier champ de signalisation (champ SIG A) contenant des premières informations de commande communes relatives à une pluralité de STA, et un second champ de signalisation (champ SIG B) contenant des informations de commande individuelles pour chacune de la pluralité de STA. Le second champ comprend un champ de signalisation commun contenant des secondes informations de commande communes relatives à la pluralité de STA, et un champ individuel consécutif au champ commun et contenant des informations de commande individuelles pour chacune des STA. Un champ individuel (un premier champ individuel) du second champ de signalisation, qui est transmis à partir d'une bande particulière de 20 MHz (une première bande) peut contenir : des informations d'attribution de ressources relatives à une ou plusieurs STA de première bande, auxquelles des ressources sont attribuées dans la première bande ; et des informations d'attribution de ressources relatives à une ou plusieurs STA de seconde bande, auxquelles des ressources sont attribuées à partir d'une autre bande de 20 MHz (une seconde bande) différente de la première bande. Par conséquent, la longueur du premier champ individuel peut être définie comme étant égale à la longueur du champ individuel (second champ individuel) du second champ de signalisation transmis à partir de la seconde bande.
(KO) 본 발명의 일 실시예에 따른 무선랜 시스템에서 AP (Access Point)의 무선 프레임 전송 방법은, AP에서 시그널링 필드 및 데이터 필드를 포함하는 무선 프레임을 생성하되, 시그널링 필드는 복수의 STA에 대한 제 1 공통 제어 정보를 포함하는 제 1 시그널링 필드(SIG A 필드), 및 복수의 STA 각각에 개별적인 제어 정보를 포함하는 제 2 시그널링 필드(SIG B 필드)를 포함하고, 제 2 시그널링 필드는 복수의 STA에 대한 제 2 공통 제어 정보를 포함하는 공통 필드, 및 공통 필드에 후속하며 상기 복수의 STA 각각에 개별적인 제어 정보를 포함하는 개별 필드를 포함한다. 이때, 특정 20MHz 대역(제 1 대역)에서 전송되는 제 2 시그널링 필드의 개별 필드(제 1 개별 필드)는, 제 1 대역에서 자원이 할당되는 하나 이상의 제 1 대역 STA에 대한 자원 할당 정보, 및 제 1 대역 이외의 다른 20MHz 대역(제 2 대역)에서 자원이 할당되는 하나 이상의 제 2 대역 STA에 대한 자원 할당 정보를 포함할 수 있다. 이를 통해 상기 제 1 개별 필드의 길이는 상기 제 2 대역에서 전송되는 상기 제 2 시그널링 필드의 개별 필드(제 2 개별 필드)의 길이와 동일하게 설정될 수 있다.
