Abstract: Proposed is 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 an EHT PPDU from a transmission STA via 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 on a tone plan. The information on the tone plan includes allocation information indicating that a tone plan for the 320 MHz band is configured by four iterations of a tone plan for an 80 MHz band, which is defined in an 802.11ax wireless LAN system. The data field is received via an RU configured based on the allocation information.

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: A method and apparatus for transmitting an EHT PPDU in a wireless LAN system is proposed. Specifically, a transmitting STA generates an EHT PPDU including a STF signal. The transmitting STA transmits the EHT PPDU to a receiving STA. The STF signal is generated on the basis of an EHT STF sequence for a 320 MHz band or a 160+160 MHz band. The EHT STF sequence for the 320 MHz band is a first sequence in which a predetermined M sequence is repeated, which is defined as {M 1 M 1 M 1 −M 0 M 1 −M 1 −M 1 M 0 M 1 M 1 M 1 −M 0 −M −1 M −1 M −1 −M}*(1+j)/sqrt(2). The sqrt( ) represents the square root. The predetermined M sequence is defined as M={−1, −1, −1, 1, 1, 1, −1, 1, 1, 1, −1, 1, 1, −1, 1}.

Abstract: In a wireless local area network system, a station (STA) may perform binary convolutional code (BCC) encoding on a data field. The STA may puncture the data field in a first puncturing pattern and may transmit a physical protocol data unit (PPDU) including a control field and the data field. The control field may include control information related to the first puncturing pattern.

Abstract: Proposed are a method and device for transmitting EHT PPDU in a wireless LAN system. Particularly, a transmission STA generates first and second LTF symbols. The transmission STA transmits EHT PPDU comprising the first and second LTF symbols to a reception STA. The first and second LTF symbols are generated on the basis of an LTF sequence for first to fourth spatial streams. In the first LTF symbol, the LTF sequence for the first to fourth spatial streams is mapped to tones in four tone units in a frequency domain. In the second LTF symbol, the LTF sequence for the first to fourth spatial streams is mapped to tones in four tone units in a frequency domain. The LTF sequence, for the first to fourth spatial streams, mapped to the frequency domain of the second LTF symbol is mapped to a tone by means of cyclic shifting, by two tones, the LTF sequence, for the first to fourth spatial streams, mapped to the frequency domain of the first LTF symbol.

Abstract: A method and an apparatus for transmitting a PPDU in a WLAN system are proposed. Specifically, a transmitter generates a PPDU and transmits the PPDU to a receiver. The PPDU includes a legacy field and an EHT field. The legacy field includes a VHT-STF and a HE-STF. The EHT field includes an EHT-STF and a data field. The EHT field is configured on the basis of a CSD value of each transport chain. The CSD value is determined as a candidate CSD value in which the sum of a first absolute value and a second absolute value is the minimum on the basis of a power ratio. The power ratio is a ratio of a received power of the VHT-STF, the HE-STF, or the EHT-STF to a received power of the data field. The first absolute value is an absolute value of a value related to 5 percent of a CDF relative to the power ratio. The second absolute value is an absolute value of a value related to 95 percent of the CDF relative to the power ratio.

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 an apparatus for transmitting and receiving data to and from a wireless LAN system. Specifically, an AP transmits control information to an STA. The AP transmits data to or receives data from the STA on the basis of the control information.
