Abstract: A method for performing uplink Orthogonal Frequency Division Multiple Access (UL OFDMA) based random access to an Access Point (AP) by a Station (STA) in a Wireless Local Area Network (WLAN) system is proposed. For the purpose, the STA sets a random value within an OFDMA Contention Window (CWO) as an OFDMA Back-Off (OBO) value, receives a beacon frame from the AP, the beacon frame including transmission start time information of one or more Trigger Frames for Random Access (TF-Rs), decrements the OBO value based on reception of the one or more TF-Rs, and if the OBO value reaches 0, transmits a random access request frame in resources selected randomly from among resources allocated to the STA.

Abstract: Disclosed is a signal processing method for changing an operating mode for transmitting a PPDU in a wireless LAN system. Specifically, a first station transmits, to a second station, the number of spatial streams supported by the first station, and a first instructional information instructing a change of the operating mode indicating a channel bandwidth. The first station applies the first instructional information after receiving an ACK therefor. The first instructional information comprises an operating mode indicator for indicating whether the operating mode is a receive operating mode (ROM) or a transmit operating mode (TOM).
