Abstract: Presented are a method and a device for receiving a PPDU in a wireless LAN system. Particularly, 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. The first phase rotation value is acquired on the basis of a first preamble puncturing pattern of the broadband. The first preamble puncturing pattern includes the pattern in which 40 MHz or 80 MHz band is punctured in the broadband, 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].

Abstract: The present disclosure proposes a method and apparatus for aligning symbol boundaries of each field of an HE PPDU and an EHT PPDU within an A-PPDU in a wireless LAN system. In particular, a reception STA receives the A-PPDU from a transmission STA. The reception STA decodes the A-PPDU. The A-PPDU comprises an HE PPDU for a primary 160 MHz channel and an EHT PPDU for a secondary 160 MHz channel. The length from a first L-STF to an HE-SIG-A is the same as the length from a second L-STF to a U-SIG. Symbol boundaries of an HE-SIG-B and an EHT-SIG are equally aligned.

Abstract: Disclosed are a method and apparatus for a resource adaptive transmission operation related to a trigger-based transmission in a wireless LAN system. The method by which a station (STA) transmits a physical layer protocol data unit (PPDU) in a wireless LAN system, according to an embodiment of the present disclosure, comprises the steps of: receiving, from an access point (AP), trigger information including information regarding a first resource region being allocated for the STA; and transmitting, on the basis of the AP having a specific capability, a trigger-based (TB) PPDU to the AP on a second resource region, wherein the second resource region may correspond to a portion of the first resource region.

Abstract: The present specification presents a method and device for configuring a special user information field in a trigger frame even when triggering only an HE TB PPDU in a wireless LAN system. Specifically, a reception STA receives a trigger frame from a transmission STA. The reception STA transmits an HE TB PPDU to the transmission STA. A special user information field comprises a PHY version ID subfield, a second bandwidth field, fifth and sixth spatial reuse fields, a U-SIG disregard and validate subfield, and a reserved subfield. A first bandwidth field comprises information about a bandwidth at which the HE TB PPDU is transmitted. If the bandwidth at which the HE TB PPDU is transmitted is 20 MHZ, then the fifth and sixth spatial reuse fields are set to the value of a first spatial reuse field.

Abstract: Proposed are a method and apparatus for indicating a transmission band for a non-HT Dup PPDU in a wireless LAN system. Particularly, a reception STA receives a non-HT Dup PPDU from a transmission STA via a preset frequency band. The reception STA decodes the non-HT Dup PPDU. All fields of the non-HT Dup PPDU are duplicated and transmitted on every 20 MHz channel in the preset frequency band. The non-HT Dup PPDU includes a service field within a data field. The service field comprises first to sixteenth bits. The preset frequency band is configured on the basis of the sixth to eighth bits. If the preset frequency band is a 320 MHz band, the sixth bit is set to 1, the seventh bit is set to 1, and the eighth bit is set to 1.
