    Abstract: Disclosed are a method and an apparatus for initial access distribution over a wireless LAN. A method for an initial access by a station (STA) comprises: a step in which the STA receives a fast initial link setup (FILS) backoff parameter from an access point (AP); and a step in which the STA implements a backoff procedure by using the final FILS backoff parameter determined on the basis of the FILS backoff parameter and an access category of the data to be transmitted by the STA. Accordingly, the initial access of the STA can be distributed.

    Abstract: A method and apparatus of sleep mode operation in a multi-carrier system are discussed. The method of establishing a sleep mode operation through active primary and secondary carriers according to an embodiment of the present invention may include transmitting a sleep cycle ID, a listening window, and traffic indication inactive information indicating that an indication as to whether traffic is generated is not transferred to a terminal through the primary carrier, sending downlink data to the terminal through the active primary or secondary carrier during the listening window, and sending a listening window early termination indication indicating to early terminate the listening window of the primary or secondary carrier that has received the downlink data through the primary carrier to the terminal if the data sending is completed.

    Abstract: Proposed is a method and apparatus for transmitting a C-OFDMA PPDU in a wireless LAN system. Specifically, a first AP transmits a C-OFDMA request frame to a second AP. The first AP receives a C-OFDMA response frame as a response to the COFDMA request frame from the second AP. The first AP transmits a first C-OFDMA PPDU to a first STA through a first channel. A second C-OFDMA PPDU is transmitted simultaneously together with the first PPDU through a second channel by the second AP. The C-OFDMA request frame includes first information indicating that using the second channel for the second AP is allowed. The first channel corresponds to a channel remaining after excluding a preamble-punctured channel from the entire channel, and the second channel corresponds to the preamble-punctured channel.

    Abstract: A method and a device for transmitting and receiving PPDU on the basis of FDR in a wireless LAN system are presented. More particularly, an AP transmits a trigger frame to an STA. The AP transmits downlink (DL) PPDU to the STA on the basis of the AP trigger frame. The AP receives uplink (UL) PPDU from the STA on the basis of the trigger frame. The trigger frame includes a first common information field. The first common information field includes a trigger type field, a length field, and a bandwidth field. The length field comprises information on the length of the longest PPDU of the DL PPDU and the UL PPDU. The bandwidth field comprises information on the total bandwidth over which the DL PPDU and the UL PPDU are transmitted. The DL PPDU and the UL PPDU are transmitted and received on the basis of FDR.
