Abstract: The present disclosure proposes a method and a device for configuring a bandwidth field by excluding a bit indicating a specific bandwidth for a TB A-PPDU in a wireless LAN system. Specifically, a reception STA receives a trigger frame from a transmission STA. The reception STA transmits a TB PPDU to the transmission STA via a 320 MHz band. A TB A-PPDU includes an HE TB PPDU for a primary 160 MHz channel and an EHT TB PPDU for a secondary 160 MHz channel. Information on a bandwidth of the TB PPDU does not include a first case where a bandwidth in which the HE TB PPDU is transmitted is 20 MHz and a bandwidth in which the EHT TB PPDU is transmitted is 20 MHz.

Abstract: Proposed are a method and apparatus for indicating a bandwidth of a non-HT Dup PPDU managing or controlling an APPDU in a wireless LAN system. Particularly, a reception STA receives a non-HT Dup PPDU from a transmission STA. The reception STA receives an A-PPDU from the transmission STA or transmits the A-PPDU to the transmission STA, via a preset bandwidth on the basis of the non-HT Dup PPDU. All fields of the non-HT Dup PPDU are duplicated and transmitted on every 20 MHz channel that is not punctured in a preset frequency bandwidth. The A-PPDU includes an HE PPDU for a primary 160 MHz channel and an EHT PPDU for a secondary 160 MHz channel

Abstract: In a wireless local area network (WLAN) system, a transmission STA can transmit a PPDU via a 320 MHz channel, and a Medium Access Control (MAC) signal may be generated for the PPDU. The MAC signal may include puncturing pattern information and channel center frequency segment (CCFS) information for a 320 MHz band. The CCFS information may include a first CCFS field related to channel center frequency (CCF) information of a primary 160 MHz channel, and a second CCFS field related to CCF information of a 320 MHz channel.

Abstract: An embodiment of the present invention relates to a technique for configuring a signal field in a wireless communication system. A receiving STA may receive and decode a PPDU. The PPDU may include a control information field, a plurality of signal fields, and a plurality of data fields. The control information field may be duplicated based on a first bandwidth, and the plurality of signal fields may be duplicated based on a second bandwidth. The second bandwidth may be set to be larger than the first bandwidth.

Abstract: Proposed herein is a method and device for setting limited RUs and MRUs in a WLAN system. More specifically, a receiving STA receives a PPDU from a transmitting STA through a preset frequency band, and decodes the PPDU. The receiving STA is an STA operating only in a 20 MHz band. The PPDU includes a preamble and a data field. The data field is received through resources other than the first RU and the first MRU among the preset frequency band.

Abstract: Proposed are a method and a device 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 an STF signal. The STF signal is generated on the basis of a first STF sequence for the broadband. The first STF sequence is obtained on the basis of a first preamble puncturing pattern of the broadband. When the broadband is a 320 MHz band, the first preamble puncturing pattern includes a pattern in which a 40 MHz or 80 MHz band is punctured in the broadband. The first STF sequence is a sequence including an M sequence and is defined as {M 0 −M 0 M 0 −M 0 M 0 −M 0 −M 0 M 0 M 0 −M 0 −M 0 M 0 −M 0 M 0 M 0 −M}*(1+j)/sqrt(2).
