PROCÉDÉ ET DISPOSITIF DE TRANSMISSION OU DE RÉCEPTION D'INFORMATIONS SUR LA TAILLE D'UNE UNITÉ DE RESSOURCE DANS UN SYSTÈME LAN SANS FIL

摘要

An embodiment of the present specification relates to a method and a device used in a wireless local area network (WLAN) system. For example, a WLAN station (STA) may transmit information about a preferred or recommended resource unit to an access point (AP). When a resource unit having a size which does not exceed the size of the resource unit preferred/recommended by the WLAN station is allocated for uplink communication, narrowband communication is possible, thus increasing the chance of successful uplink transmission.
