Abstract: In a wireless local area network (wireless LAN) system, an initiator station (STA) can transmit a sensing initiation frame. The sensing initiation frame can include information related to a first responder STA operating as a sensing responder. The initiator STA can receive a first transmission initiation frame from the first responder STA. The first transmission initiation frame can include strength information about a first sensing signal. The initiator STA can receive the first sensing signal from the first responder STA. The sensing initiation frame can further include information related to a second responder STA operating as a sensing responder. The initiator STA can receive a second transmission initiation frame from the second responder STA. The second transmission initiation frame can include strength information about a second sensing signal. The second sensing signal can be received from the second responder STA.

Abstract: A method and an apparatus for receiving a PPDU in a wireless LAN system are proposed. Specifically, a receiving STA receives the PPDU from a transmitting STA through an 80 MHz band, and decodes the PPDU. The PPDU includes a preamble and a data field. The 80 MHz band includes first and second 484 tones RUs. The data field includes first data for the first 484 tone RU and second data for the second 484 tone RU. The second data is data obtained by duplicating the first data. The first and second 484 tone RUs are resource units including 484 tones.

Abstract: An example according to the present specification relates to a technique relating to a configuration of a preamble in a wireless LAN (WLAN) system. A reception STA can receive a PPDU. The reception STA can perform a modulo operation with respect to whether or not an L-SIG field is repeated and a value of a length field. The reception STA can determine the received PPDU as an EHT PPDU on the basis of the modulo operation with respect to whether or not the L-SIG field is repeated and the value of the length field.

Abstract: A transmitting STA can transmit a sensing initiation frame to a first receiving STA in a wireless local area network (wireless LAN) system. The sensing initiation frame can include information related to an STA for transmitting a sounding frame and a session identifier (ID) related to an STA group that is to perform sensing. The transmitting STA can transmit the sounding frame to the first receiving STA. The transmitting STA can receive a first feedback frame for the sounding frame from the first receiving STA. The sounding frame can be a frame transmitted to identify a target. The first feedback frame can include information about a channel changed by means of the target. The sounding frame can include a null data packet announcement (NDPA) frame and a null data packet (NDP) frame.

Abstract: In a Wireless Local Area Network system, an STA may receive a trigger frame from an AP. The trigger frame may include a common information field and user information fields. Each of the user information fields may include a first field related to an association identifier (AID) and a second field including information for the STA related to the AID. The second field may include special information for every STA receiving the trigger frame on the basis that the first field has a specific value. The common information field may include a present field related to whether a user information field in which the first field has the specific value is present among the user information fields.

Abstract: A method and a device for receiving a PPDU in a wireless LAN system are presented. Specifically, 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. 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].

Abstract: In a wireless local area network (WLAN) system, in a case where data is being transmitted through a link, a transmission multi-link device (MLD) may perform back-off through another link during a time interval in which a PPDU is not transmitted through the link for the data transmission. Further, the transmission MLD may perform back-off again if a TXOP of the link for the data transmission is not over when a BC becomes 0.

Abstract: Proposed are a method and an apparatus for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives a PPDU from a transmission STA through a broadband and decodes the PPDU. The PPDU includes a legacy preamble, and a first and a second signal field. The legacy preamble and the first and the second signal field are generated on the basis of a first phase rotation value. When a first band is a 40 MHz band, the first phase rotation value is [1, −1, −1, −1]. Each element of the first phase rotation value is applied for each 10 MHz band in the first band.

Abstract: In a wireless local area network system, a transmitting MLD may transmit a PPDU to a receiving MLD, and receive a BA frame therefor. The BA frame may comprise power state information for STAs transitioning from a doze state to an awake state among STAs included in the receiving MLD, and the transmitting MLD may transmit data on the basis thereof.

Abstract: A multi-link device (MLD) in a wireless local area network (WLAN) system is proposed. The MLD may include an access point (AP) MLD. The AP MLD may receive receiving, from a non-simultaneous transmit and receive (Non-STR) station (STA) MLD, a multilink aggregation request signal through a first link. The multilink aggregation request signal may include first information related to a second link for which aggregation is requested and second information related to a transmission opportunity (TXOP) to be set in the second link. The AP MLD may obtain the TXOP based on the second information in the second link. The AP MLD may transmit, to the Non-STR STA MLD, a first multilink aggregation response signal through the first link and a second multilink aggregation response signal through the second link.
