  • Patent number: 12294541
    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.

  • Patent number: 11979871
    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.

  • Patent number: 11777651
    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.

  • Patent number: 11576178
    Abstract: A method and a device for transmitting a PPDU in a WLAN system are proposed. Specifically, a transmission device generates a PPDU and transmits the PPDU to a reception device through a 320 MHz band. The PPDU includes a legacy preamble and an EHT field, and the legacy preamble includes an L-STF and an L-LTF. The legacy preamble is generated by applying a first phase rotation value or a second phase rotation value. The first phase rotation value is obtained based on a third phase rotation value and a fourth phase rotation value. The third phase rotation value is a phase rotation value obtained by repeating a phase rotation value defined when the PPDU is transmitted in an 80 MHz band four times. The fourth phase rotation value is a phase rotation value defined for each 80 MHz band in the 320 MHz band based on an optimal PAPR of the L-STF.
