    Abstract: Proposed are a method and device for transmitting an ML element for ML reconfiguration in a wireless LAN system. Particularly, a reception MLD generates a first ML element for ML reconfiguration. The reception MLD transmits the first ML element to a transmission MLD via a first link. The first ML element comprises a profile subelement of a second reception STA. The profile subelement of the second reception STA comprises a first STA control field. The first STA control field comprises an STA MAC address present subfield. If the value of the STA MAC address present subfield is 1, then the profile subelement of the second reception STA further comprises an STA MAC address subfield.

    Abstract: Proposed are a method and device for receiving a feedback frame in a wireless LAN system. Specifically, a beamformer receives a feedback frame for MIMO beamforming from a beamformee and decodes the feedback frame. The feedback frame includes a first feedback tone for a preset frequency band. When the preset frequency band is the 20 MHz band, the tone index of the first feedback tone is set to [−122, −116:8:−4, −2, 2, 4:8:116, 122] when Ng is 8, and [−122, −116, −108:32:−12, −4, −2, 2, 4, 12:32:108, 116, 122] when Ng is 32. When the preset frequency band is the 40 MHz band, the tone index of the first feedback tone is set to [−244:8:−4, 4:8:244] when Ng is 8, and [−244, −236:32:−12, −4, 4, 12:32:236, 244] when Ng is 32.

    Abstract: Proposed are a method and an apparatus for receiving an MAC address of another STA within a reception MLD in a wireless LAN system. Specifically, the reception MLD receives an ML element from a transmission MLD through a first link. The reception MLD decodes the ML element. The ML element includes common information and link information. The link information includes a profile field of the second transmission STA. The profile field of the second transmission STA includes first information relating to whether an MAC address of the second transmission STA exists. If the first information is configured to be 1, the profile field of the second transmission ST A includes the MAC address of the second transmission STA.

    Abstract: A method and an apparatus for transmitting an EHT PPDU to a WLAN system are proposed. Specifically, a transmitter generates and transmits an EHT PPDU to a receiver through a 320 MHz band from which an 80 MHz band is punctured. The EHT PPDU includes a legacy preamble and an EHT field. The legacy preamble includes an L-STF and an L-LTF. The legacy preamble is generated by applying a first phase rotation value. The first phase rotation value is obtained on the basis of a second phase rotation value and a third phase rotation value. The second phase rotation value is a phase rotation value that repeats a phase rotation value defined for the 80 MHz band in an 802.11ax system. The third phase rotation value is a phase rotation value defined in unit of the 80 MHz band in the 320 MHz band on the basis of an optimal PAPR of the L-STF and L-LTF. The first phase rotation value is [1 1 −1 −1 −j −j j j 1 1 −1 −1 −j −j j j].

    Abstract: The present disclosure is related to a long training field (LTF) sequence for 320 MHz band transmission in a wireless local area network system. The main features comprise the steps of: generating a physical protocol data unit (PPDU); and transmitting the PPDU through a 320 MHz band, wherein the PPDU includes an LTF signal and the LTF signal is generated on the basis of an LTF sequence for the 320 MHz band. Therefore, the proposed LTF has improved effects such as increased bandwidth, an improved PHY layer protocol data unit (PPDU) structure, an improved sequence, and use of a hybrid automatic repeat request (HARQ) technique.
