    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.
