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 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: One example according to the present specification relates to a technique related to configuration of a preamble in a wireless LAN (WLAN) system. According to various embodiments, a receiving STA may receive an NDP frame. The NDP frame may comprise a first signal field and a second signal field. The first signal field may comprise first information about a PHY version. The second signal field may comprise second information about transmission of a PPDU, set on the basis of the first information. The receiving STA may perform channel sounding on the basis of the NDP frame.

Abstract: A method and a device for receiving a PPDU in a wireless LAN system are presented. Specifically, a receiving STA receives a PPDU from a transmitting STA through a broadband and decodes the PPDU. The PPDU includes a legacy preamble and first and second signal fields. The legacy preamble and the first and second signal fields are generated on the basis of a first phase rotation value. When the broadband is a 320 MHz band, the first phase rotation value is [1 1 1 −1 1 1 1 −1 −1 −1 −1 1 −1 −1 1 −1].
