Abstract: One embodiment according to the present specification relates to a technique for multiple frame transmission in a wireless LAN (WLAN) system. A transmission STA can transmit a first next generation V2X physical protocol data unit (NGV PPDU) from among a plurality of NGV PPDUs for a multiple frame transmission mode. Afterwards, the transmission STA can identify a channel state for the transmission of a second NGV PPDU from among the plurality of NGV PPDUs. The transmission STA can determine, on the basis of the channel state, whether to transmit the second NGV PPDU.

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.

Abstract: An example according to the present specification relates to a technique for filtering a PPDU in a wireless LAN (WLAN) system. An STA may receive an NGV PPDU including a first control field and a second control field. The STA may filter the NGV PPDU on the basis of the second control field and may defer channel access on the basis of the first control field.

Abstract: Proposed are a method and device for performing sensing in a wireless LAN system. Specifically, a transmission STA generates a frame. The transmission STA transmits the frame to a reception STA in a 60 GHz band. The frame includes an EDMGHeader-A field. A reserved bit of the EDMG-Header-A field includes a packet classification descriptor. The packet classification descriptor includes information indicating that the frame is a sensing frame used for sensing.

Abstract: Presented are a method and a device for receiving a PPDU in a wireless LAN system. Particularly, a receiving STA receives a PPDU from a transmitting STA through a broadband, and decodes the PPDU. The PPDU includes a legacy preamble and first and second signal fields. The legacy preamble and the first and second signal fields are generated on the basis of a first phase rotation value. The first phase rotation value is acquired on the basis of a first preamble puncturing pattern of the broadband. The first preamble puncturing pattern includes the pattern in which 40 MHz or 80 MHz band is punctured in the broadband, when the broadband is a 320 MHz band. The first phase rotation value is [1 −1 −1 −1 1 −1 −1 −1 −1 1 1 1 −1 1 1 1].
