    Abstract: Proposed are a method and apparatus for receiving a PPDU on which BCC interleaving has been performed in a Multi-RU in a wireless LAN system. Specifically, a reception STA receives, from a transmission STA, a PPDU comprising a data field and decodes the data field. The data field is received via a Multi-RU which is an aggregate of a first RU and a second RU. The data field is generated on the basis of a coded bit string included in a BCC interleaver block. The coded bit string is obtained by interleaving a data bit string on the basis of first and second parameters. The data bit string is interleaved as the data bit string is entered into the BCC interleaver block in rows on the basis of the first parameter and is read out in columns of the BCC interleaver block on the basis of the second parameter.

    Abstract: Proposed are a method and device for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives the PPDU from a transmission STA through a wideband and decodes the PPDU. The PPDU includes an STF signal. The STF signal is generated on the basis of a first STF sequence for the wideband. When the wideband is a 320 MHz band, the first STF sequence is a sequence including a M sequence and is defined as {M −1 M −1 −M −1 M 0 −M 1 M 1 −M 1 −M 0 M −1 M −1 −M −1 M 0 −M 1 M 1 −M 1 −M 0 −M 1 −M 1 M 1 −M 0 M −1 −M −1 M −1 M 0 −M 1 −M 1 M 1 −M 0 M −1 −M −1 M −1 M}*(1+j)/sqrt(2).

    Abstract: Proposed are a method and an apparatus for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives a PPDU from a transmission STA through a first band and decodes the PPDU. The PPDU includes a control field and a data field. The first band is an 80 MHz band including first and second 20 MHz subchannels and a first 40 MHz subchannel. When the first 20 MHz subchannel is punctured, the second 20 MHz subchannel includes a first multi-RU in which first and second 26-RUs, 52-RUs, and 106-RUs are aggregated. The first 40 MHz subchannel includes a 484-RU. The data field is received through a second multi-RU in which the first multi-RU and the 484-RU are aggregated.

    Abstract: Proposed are a method and apparatus for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives a PPDU from a transmission STA through a broadband and decodes the PPDU. The PPDU includes a control field and a data field. When the broadband is a 320/160+160 MHz band including first to fourth 80 MHz sub-channels, the first 80 MHz sub-channel includes a first 996 RU, the second 80 MHz sub-channel includes a second 996 RU, the third 80 MHz sub-channel includes a third 996 RU, and the fourth 80 MHz sub-channel includes a first 484 RU. The data field is received through a first multiple RU in which the first to third 996 RUs and the first 484 RU are aggregated.

    Abstract: The present specification proposes a method for configuring a trigger frame that can be applied to a next-generation Wireless LAN (WLAN) system and an apparatus using the method. As an example, the trigger frame of the present specification may set a bandwidth for a trigger-based (TB) PPDU of up to 320 MHz. As another example, the trigger frame of the present specification may set the format of the TB PPDU transmitted through a primary bandwidth. As another example, the trigger frame of the present specification may trigger an aggregated PPDU (A-PPDU).

    Abstract: The present document relates to a method and device for an Access Point (AP) to transmit ACK/NACK signals for MU (Multi-User) transmission data of a plurality of stations (STA) in a wireless LAN (WLAN) system. To this end, the method and device are characterized in that a STA responds to a trigger frame received from an AP, transmits data to the AP through an MU access technique, and sets an ACK policy value for data transmitted on the basis of the trigger frame to another value other than a first ACK policy value requesting an ACK signal transmission on the basis of a block ACK request.
