Abstract: 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 user specific 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.

Abstract: Proposed is a control field including allocation information regarding a resource unit (RU) in a wireless local area network (WLAN) system supporting a plurality of RUs. A data field may be transmitted in unit of the RU. For a case where two 106-RUs are arranged and a plurality of user stations (STAs) are multiplexed to the respective 106-RUs, a SIG-B field may be used to perform signaling. More specifically, the number of STAs to be multiplexed may be indicated by using first and second identification bits in a user-common field of the SIG-B field.

Abstract: A method for receiving a signal by a station in a wireless LAN system, according to an embodiment of the present invention, comprises the steps of: receiving one of a plurality of per channel SIG-Bs, comprised in a SIG-B field, via a first channel among the transmission bandwidth of a multi-user (MU) frame comprising SIG-B field and data; and receiving the data of the MU frame on a second channel differing from the first channel via which the per channel SIG-Bs have been received. Although any one of the plurality of per channel SIG-Bs is transmitted on the second channel, the data of the MU frame is received by means of the per channel SIG-Bs that are transmitted on the first channel instead of the per channel SIG-Bs that are transmitted on the second channel.
