Abstract: Proposed are a method and device for receiving an EHT PPDU on the basis of a tone plan in a wireless LAN system. Specifically, a reception STA receives the EHT PPDU from a transmission STA through a 320 MHz band. The reception STA decodes the EHT PPDU. The EHT PPDU includes a control field and a data field. The control field includes information about a pilot tone. The information about the pilot tone includes allocation information indicating that a first pilot tone for the 320 MHz band is configured by repeating a second pilot tone for an 80 MHz band defined in an 802.11ax wireless LAN system. The first pilot tone is received in a data field on the basis of the allocation information.

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: A method and a device for transmitting a PPDU in a WLAN system are proposed. Specifically, an AP generates a PPDU and transmits the PPDU to a STA through a broadband. The PPDU includes an EHT-LTF and a data field. The data field includes a pilot tone. The coefficient of the pilot tone is set to a second pilot sequence in which a first pilot sequence is repeated. The first pilot sequence is {1 1 1 −1 −1 1 1 1}.

Abstract: Provided are a method and apparatus for transmitting a frame in a wireless LAN (WLAN) system. Specifically, a first station (STA) transmits a Link Measurement Request frame requesting Transmit Power Control (TPC) information to a second STA. The first STA receives a Link Measurement Report frame from the second STA. The Link Measurement Report frame being transmitted as a response to the Link Measurement Request frame. The Link Measurement Request frame includes a TPC Configuration field. The TPC Configuration field includes a first sub-field and a second sub-field. The first sub-field includes information on whether or not the Link Measurement Request frame is transmitted through a channel on which channel aggregation is performed. The second sub-field includes information on a number of transmit chains being used for transmitting the Link Measurement Request frame. If the Link Measurement Request frame is transmitted through the channel on which the channel aggregation is performed, the number of transmit chains is equal to an even number.
