    Abstract: An example according to the present disclosure relates to a technique for identifying a wireless LAN (WLAN) packet. For example, when a physical protocol data unit (PPDU) includes a legacy signal field, a field contiguous to the legacy signal field may be used to identify a type of the PPDU. A field contiguous to the legacy signal field may include information indicating that the PPDU is an extreme high throughput (EHT) PPDU. The field contiguous to the legacy signal field may include at least one of information related to a frame format, a transmission opportunity, an STA ID, and/or a bandwidth.

    Abstract: Proposed are a method and a device for receiving a PPDU in a wireless LAN system. Specifically, a receiving STA receives a PPDU from a transmitting STA through a first band, and decodes the PPDU. The PPDU comprises a control field and a data field. When the first band is an 80 MHz band comprising first to fourth 20 MHz subchannels, the first 20 MHz subchannel comprises first multiple RUs in which a first 26RU and a first 52RU are aggregated. The first 26RU is an RU located in the middle of the first 20 MHz subchannel. The first 52RU is an RU having a frequency lower than that of the first 26RU, and which is adjacent to the first 26RU.

    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 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.
