Method for transmitting data transmission resource allocation information in wireless lan system, and apparatus therefor

The present document relates to a method for allocating resources for multi-user or multi-station (STA) data transmission in a wireless LAN system, and an apparatus therefor. To this end, an AP generates a frame including a signaling field and a data field, wherein the signaling field includes a first signaling field (SIG A field) comprising common control information for a plurality of STAs and a second signaling field (SIG B field) comprising individual control information for each of the plurality of STAs, the second signaling field also comprising data transmission resource allocation information for each of the plurality of STAs. The AP transmits the thus generated frame to the plurality of STAs. If the frame is transmitted with a bandwidth of 40 MHz or greater, the second signaling field transmits independent control information in two adjacent 20 MHz bands, and the second signaling field, transmitted through a specific 20 MHz band, comprises data transmission resource allocation information within the specific 20 MHz band.
