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: Disclosed are a method and an apparatus for generating an STF signal usable in a wireless LAN system. The STF signal is included in a field used to improve AGC estimation of a MIMO transmission. The STF signal that is suggested, for example, can be used for an 80 MHz band and can be generated based on a sequence in which a predetermined M sequence is repeated. Also, the disclosed STF signal can be used for a 1× STF signal from the 1× STF signal and a 2× STF signal. The predetermined M sequence can be a binary sequence of which the length is 15 bits.
