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: A method and a device for signaling an ERSP in a wireless LAN system are presented. Specifically, a first reception STA receives a beacon frame from a transmission STA. The first reception STA receives a first frame from the transmission STA during an RSP. The beacon frame includes allocation information about the RSP. The first frame includes signaling information about the ERSP having an extended RSP. The first frame is transmitted when the ERSP starts. The signaling information about the ERSP includes information about whether an ERSP is present, information about the time when the ERSP ends, and information about the duration of the ERSP.

Abstract: The present specification proposes a new procedure of signal transmission or reception between STAs in a case of sensing measurement initiated by an STA rather than an AP. According to an embodiment of the present specification, proposed is a sensing measurement procedure performed by an AP in response to transmission of a sensing initiation frame to the AP by an STA rather than the AP. According to another embodiment of the present specification, according to an embodiment of the present specification, proposed is a procedure in which an STA rather than an AP transmits a sensing initiation frame to the AP, and then the AP requests respondent STAs to transmit NDP frames. According to yet another embodiment of the present specification, proposed is a method for configuring a frame transmitted or received in the above procedures.
