Abstract: Proposed are a method and an apparatus 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 a legacy preamble, and a first and a second signal field. The legacy preamble and the first and the second signal field are generated on the basis of a first phase rotation value. When a first band is a 40 MHz band, the first phase rotation value is [1, −1, −1, −1]. Each element of the first phase rotation value is applied for each 10 MHz band in the first band.

Abstract: According to various embodiments, a reception STA may receive a physical layer protocol data unit (PPDU) including a first field and a second field from a transmission STA. The first field may include information about a configuration of a plurality of resource units (RUs). The second field may include a plurality of user fields for allocating the plurality of RUs to a plurality of users. The reception STA may identify a multiple RU (M-RU) allocated to itself and decode the received PPDU.

Abstract: Proposed are a method and device for receiving a feedback frame for MIMO beamforming in a wide band in a wireless LAN system. Specifically, a reception STA receives an NDPA frame from a transmission STA. The reception STA receives an NDP frame from the transmission STA. The reception STA transmits a feedback frame to the transmission STA on the basis of the NDP frame. The feedback frame includes information about a feedback subcarrier for the wide band. When the wide band is a continuous 320 MHz band and the grouping value is Ng, the indexes of the feedback subcarrier are set to [−2036:Ng:−1540], [−1532:Ng:−1036], [−1012:Ng:−516], [−508:Ng:−12], [12:Ng:508], [516:Ng:1012], [1036:Ng:1532] and [1540:Ng:2036].

Abstract: One example according to the present specification relates to a method for identifying the format of a PPDU in a wireless LAN (WLAN) system. A receiving STA may receive a first PPDU. The receiving STA may check at least one extra tone of at least one symbol of the first PPDU. The receiving STA may determine, on the basis of the at least one extra tone, the format of the first PPDU as a repeated PPDU format. Thereafter, the receiving STA may receive a second PPDU including the same data as the first PPDU.

Abstract: Proposed are a method and an apparatus 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 broadband is a 320 MHz band or a 160+160 MHz band. The PPDU includes a first field and a second field. The first field includes an L-STF and an L-LTF. The first field is generated on the basis of a first phase rotation value. The first phase rotation value is generated on the basis of a second phase rotation value and a third phase rotation value. The second phase rotation value is obtained by repeating a phase rotation value for a 160 MHz band, defined in an 802.11ax wireless LAN system.

Abstract: Proposed is a method and device for receiving an EHT PPDU on the basis of a tone plan in a wireless LAN system. Specifically, a reception STA receives an EHT PPDU from a transmission STA via a 320 MHz band. The reception STA decodes the EHT PPDU. The EHT PPDU includes a control field and a data field. The control field includes information on a tone plan. The information on the tone plan includes allocation information indicating that a tone plan for the 320 MHz band is configured by four iterations of a tone plan for an 80 MHz band, which is defined in an 802.11ax wireless LAN system. The data field is received via an RU configured based on the allocation information.

Abstract: Proposed are a method and an apparatus for receiving an MU PPDU in a wireless LAN system. Specifically, a receiving STA receives an MU PPDU from a transmitting STA. The receiving STA decodes the MU PPDU. The MU PPDU includes an LSIG field, an RL-SIG field, an HE-SIG field, and an EHT-SIG field. A first reserved bit of the L-SIG field includes information indicating that a first band in which the MU PPDU is transmitted is greater than 160 MHz. A second reserved bit of the HE-SIG field includes information relating to a second band in which the EHT-SIG field is transmitted or the size of the first band. The receiving STA includes an HE STA and an EHT STA.

Abstract: The present specification provides a technical feature for extended range transmission in a wireless LAN signal. A physical protocol data unit (PPDU) of the present specification may include a universal signal (U-SIG) field. The U-SIG field may be received through first to the fourth symbols, the second symbol may include information in which bit information of the first symbol is repeated, and the fourth symbol may include information in which bit information of the third symbol is repeated. The receiving STA of the present specification may determine the transmission mode of the PPDU based on constellation mapping pattern of the first and second symbols.
