摘要
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].
