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: 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 preamble and a data field. The first band includes first to fourth sub-blocks. The data field includes first data for first and second sub-blocks and second data for third and fourth sub-blocks. The second data is generated on the basis of data obtaining by duplicating the first data and applying phase rotation to the third sub-block.

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. In detail, a reception STA receives a PPDU from a transmission STA through a first band and decodes the PPDU. The PPDU includes a preamble and a data field. The first band includes first and second subblocks. The data field includes first data for the first subblock and second data for the second subblock. The first data is generated on the basis of data in which constellation mapping is performed on encoded data bits. The second data is generated on the basis of data obtaining by duplicating the first data and applying phase rotation thereto.

Abstract: Proposed are a method and a device for requesting partial information on APs in a transmission MLD in a WLAN system. Specifically, a receiving MLD transmits a probe request frame to a transmission MLD through a first link. The receiving MLD receives a probe response frame from the transmission MLD through the first link. The probe request frame includes a profile field of the second receiving STA. The profile field of the second receiving STAincludes a first full information profile subfield. When the first receiving STA requests partial information on the second link, the value of the first full information profile subfield is set to 0, and the profile field of the second receiving STA further includes a first request element. The partial information on the second link is requested on the basis of the first request element.

Abstract: An example according to the present disclosure relates to a technique for identifying a wireless LAN (WLAN) packet. For example, when a physical protocol data unit (PPDU) includes a legacy signal field, a field contiguous to the legacy signal field may be used to identify a type of the PPDU. A field contiguous to the legacy signal field may include information indicating that the PPDU is an extreme high throughput (EHT) PPDU. The field contiguous to the legacy signal field may include at least one of information related to a frame format, a transmission opportunity, an STA ID, and/or a bandwidth.

Abstract: Proposed are a method and a device for transmitting and receiving important update information of another AP through an ML element in a WLAN system. Specifically, a receiving MLD receives a basic ML element from a transmitting MLD over a first link. The receiving MLD decodes the basic ML element. The basic ML element includes a profile field of the second transmitting STA. The profile field of the second transmitting STA includes a first CSF presence field. When the value of the first CSF presence field is set to 0, the profile field of the second transmitting STA includes a first CSF field. The first CSF field includes information about the current change sequence number of the second transmitting STA.
