Abstract: Proposed are a method and an apparatus for configuring a space reuse field in a WLAN system. Specifically, a receiving STA receives a trigger frame from a transmitting STA. The receiving STA transmits a TB PPDU to the transmitting STA through a 320 MHz band. The trigger frame includes first and second non-HT Dup PPDUs. In a first non-HT Dup PPDU, all fields are copied and transmitted for each 20 MHz channel over a first 160 MHz channel having a low frequency within a 320 MHz band. In a second non-HT Dup PPDU, all fields are copied and transmitted for each 20 MHz channel over a second 160 MHz channel having a high frequency within the 320 MHz band. The first non-HT Dup PPDU includes a first common information field and a first special user information field. The second non-HT Dup PPDU includes a second common information field and a second special user information field.

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.
