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.

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.
