Summary:The present document relates to a wireless communication system and, more specifically, to a method for flexibly supporting resource allocation in a wireless LAN system, and a signal transmission method and device using the same. To this end, an STA prepares resource allocation information in which data is to be transmitted to a plurality of STAs by using an orthogonal frequency divisional multiple access (OFDMA) scheme or a multiple user MIMO (MU-MIMO) scheme, so as to transmit the resource allocation information to the plurality of STAs, and transmits the data to the plurality of STAs according to the resource allocation information, wherein the resource allocation information preferably includes a group ID indicating the plurality of STAs, a resource allocation bitmap having a format in common with the plurality of STAs, resource allocation information for each of the plurality of STAs and resource allocation sequence information indicating a resource allocation order of the STAs in the group. La présente invention concerne un système de communication sans fil, et plus particulièrement un procédé de prise en charge souple de l'affectation de ressources dans un système LAN sans fil, ainsi qu'un procédé et un dispositif de transmission de signal qui en font usage. À cet effet, une STA prépare des informations d'affectation de ressources devant servir à la transmission de données à une pluralité de STA au moyen d'un système d'accès multiple par répartition en fréquence orthogonale (OFDMA) ou d'un système MIMO multiutilisateur (MU-MIMO), de manière à transmettre les informations d'affectation de ressources à la pluralité de STA, et transmet les données à la pluralité de STA selon les informations d'affectation de ressources, les informations d'affectation de ressources comprenant de préférence un ID de groupe qui désigne la pluralité de STA, une table de bits d'affectation de ressources dont le format est commun à la pluralité de STA, des informations d'affectation de ressources pour chacune des STA et des informations de séquence d'affectation de ressources qui indiquent un ordre d'affectation de ressources des STA du groupe. 본 문서는 무선 통신 시스템에 대한 것으로, 보다 상세하게는 무선랜 시스템에서 유연하게 자원할당을 지원하는 방법, 이를 이용한 신호 전송 방법과 장치에 대한 것이다. 이를 위해 STA은 OFDMA (Orthogonal Frequency Divisional Multiple Access) 또는 다중 사용자 MIMO (MU-MIMO) 방식으로 복수의 STA에 데이터를 전송할 자원 할당 정보를 마련하여 상기 복수의 STA에 전송하고, 상기 자원 할당 정보에 따라 상기 복수의 STA에 데이터를 전송한다. 이때, 상기 자원 할당 정보는 상기 복수의 STA을 나타내는 그룹 ID, 상기 복수의 STA에게 공통되는 형태를 가지는 자원 할당 비트맵, 상기 복수의 STA 각각에 대한 자원할당 정보 및 그룹 내 자원 할당을 받는 STA의 순서를 지정하는 자원할당순서정보를 포함하는 것이 바람직하다.
