Abstract: Proposed are a method and a device for configuring a spatial reuse field in a wireless LAN system. Specifically, a reception STA receives a trigger frame from a transmission STA. The reception STA transmits a TB PPDU to the transmission STA through a pre-configured frequency band. The trigger frame comprises a common information field and a special user information field. The common information field comprises first to fourth spatial reuse fields. The special user information field comprises fifth and sixth spatial reuse fields. When the pre-configured frequency band is a 20 MHz band, the first to fourth spatial reuse fields are configured by the value of the fifth spatial reuse field.

Abstract: One embodiment according to the present specification relates to a method for constructing a preamble in a wireless LAN (WLAN) system. According to various embodiments, a PPDU may comprise a first signal field and a second signal field. The first signal field may include first information about PHY version. The first information may be determined on the basis of whether the PPDU is an EHT PPDU. The second signal field may include second information about the transmission of the PPDU, which is set on the basis of the first information.

Abstract: Proposed herein is a method and device for setting limited RUs and MRUs in a WLAN system. More specifically, a receiving STA receives a PPDU from a transmitting STA through a preset frequency band, and decodes the PPDU. The receiving STA is an STA operating only in a 20 MHz band. The PPDU includes a preamble and a data field. The data field is received through resources other than the first RU and the first MRU among the preset frequency band.

Abstract: The present document relates to a method and device for an Access Point (AP) to transmit ACK/NACK signals for MU (Multi-User) transmission data of a plurality of stations (STA) in a wireless LAN (WLAN) system. To this end, the method and device are characterized in that a STA responds to a trigger frame received from an AP, transmits data to the AP through an MU access technique, and sets an ACK policy value for data transmitted on the basis of the trigger frame to another value other than a first ACK policy value requesting an ACK signal transmission on the basis of a block ACK request.

Abstract: Proposed are a method and device for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives the PPDU from a transmission STA through a wide band, 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 in a wide band. When the wide band is a 240 MHz band, the first preamble puncturing pattern includes a pattern in which a 40 MHz or 80 MHz band in the wide band is punctured. The first phase rotation value is [1 1−1 1 −1 1 −1 −1 −1 −1 1 1].
