Abstract: Proposed are a method and device for configuring a field for instructing the transmission of an A-PPDU in a wireless LAN system. Specifically, a reception STA receives an A-PPDU from a transmission STA. The reception STA decodes the A-PPDU. The A-PPDU includes an HE PPDU for a primary 160 MHz channel and an EHT PPDU for a secondary 160 MHz channel. The EHT PPDU includes first and second U-SIG fields. The first U-SIG field includes a UL/DL field. The second U-SIG field includes a PPDU type and compression mode field. When the value of the UL/DL field is set to 0 and the value of the PPDU type and compression mode field is set to 3, the PPDU type and compression mode field includes information for notifying that the A-PPDU has been transmitted, and the EHT PPDU is transmitted using DL MU OFDMA.

Abstract: The present disclosure proposes a method and an apparatus for transmitting capability information of a receiving STA in a wireless LAN system. Specifically, the receiving STA generates capability information of the receiving STA and transmits same to a transmitting STA. The capability information of the receiving STA includes an HE capabilities element and an EHT capabilities element. The HE capabilities element includes a supported channel width set field. The EHT capabilities element includes a supported EHT-MCS and NSS set field. The supported EHT-MCS and NSS set field includes first to fourth subfields. The first subfield includes information on the maximum number of spatial streams that the receiving STA can transmit and receive in each MCS when the receiving STA is a non-AP STA that operates only at 20 MHz and is allocated to a first transmission bandwidth.

Abstract: The present specification proposes a technique indicating a subchannel for a subchannel selective transmission (SST) operation of a wireless LAN system. For example, the present specification proposes an SST technique for supporting a maximum of 320 MHz band. The present specification proposes a technique for transmitting/receiving request information regarding a subchannel via a target wake time (TWT) request, and a technique for transmitting/receiving response information regarding a subchannel via a TWT response. The present specification proposes various techniques for displaying information regarding a TWT subchannel. The present specification proposes various techniques for constructing a bitmap for a TWT subchannel. A station (STA) of the present specification may perform an SST operation on the basis of a subchannel requested/responded according to various methods.

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: 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: 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 1 −M 0 M −1 −M −1 M −1 M}*(1+j)/sqrt(2).
