Abstract
(EN)
One example according to the present specification relates to a method and/or apparatus for receiving a signal in a WLAN system. A user station (user STA) of the present specification may receive a signal comprising a user-specific control field for Multi-User (MU) communication. In this case, the user-specific control field may comprise: a first information field related to the number of spatial streams for the user station (user STA); and a second information field comprising information related to the size of the first information field. The user station of the present specification may comprise a step of decoding a data field on the basis of the user-specific control field.

Un exemple selon la présente invention concerne un procédé et/ou un appareil pour recevoir un signal dans un système WLAN. Une station d’utilisateur (STA d’utilisateur) selon la présente invention peut recevoir un signal comprenant un champ de commande spécifique à l’utilisateur pour une communication multiutilisateur (MU). Dans ce cas, le champ de commande spécifique à l’utilisateur peut comprendre : un premier champ d’informations concernant le nombre de flux spatiaux pour la station d’utilisateur (STA d’utilisateur) ; et un second champ d’informations comprenant des informations concernant la taille du premier champ d’informations. La station d’utilisateur selon la présente invention peut comprendre une étape de décodage d’un champ de données sur la base du champ de commande spécifique à l’utilisateur.
