Abstract: Proposed is a technical feature applied to an aggregated physical protocol data unit (APPDU) comprising various types of sub-PPDUs. Proposed is a technique for negotiating subchannel-related information with a plurality of stations (STAs) in order to determine bandwidths of a plurality of sub-PPDUs included in an APPDU. The APPDU is generated on the basis of a negotiated subchannel, and a signal field, including bandwidth-related information, may be configured for each of the plurality of sub-PPDUs included in the APPDU. The APPDU may be transmitted to a receiving STA through a subchannel selective transmission (SST) operation.

Abstract: The present specification proposes a subfield including information relating to whether a transmission physical protocol data unit (PPDU) or a reception PPDU is an aggregated PPDU (APPDU). An example of the present specification is related to at least one subfield included in a universal signal (U-SIG) field of an extremely high throughput (EHT) PPDU. A value of the at least one subfield proposed in the present specification comprises information relating to whether a PPDU is an APPDU or a conventional PPDU. A reception STA may identify whether a reception PPDU is a conventional PPDU or an APPDU, and normally perform a decoding operation.

Abstract: Proposed are a method and device for receiving an A-PPDU in a wireless LAN system. Specifically, a reception STA receives an A-PPDU from a transmission STA and decodes the A-PPDU. The A-PPDU includes a first PPDU for a primary 160 MHz channel and a second PPDU for a secondary 160 MHz channel. A first signal field includes information about a bandwidth in which the first PPDU is transmitted. The information about the bandwidth in which the first PPDU is transmitted includes information about a first preamble puncturing pattern punctured in a unit of a 20 MHz channel in the primary 160 MHz channel. A second signal field includes information about a second preamble puncturing pattern.

Abstract: A method and a device for receiving a PPDU in a wireless LAN system are presented. Particularly, a receiving STA receives a PPDU from a transmitting STA through a broadband and decodes the PPDU. The PPDU includes a first signal filed and a data field. A 160 MHz band includes first and second 80 MHz segments if the broadband is the 160 MHz band. The first 80 MHz segment includes first to fourth 20 MHz channels, and the second 80 MHz segment includes fifth to eighth 20 MHz channels. The first signal field includes first and second signal CCs for the first 80 MHz segment and includes third and fourth signal CCs for the second 80 MHz segment.

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).
