    Abstract: A method and an apparatus for transmitting an EHT PPDU to a WLAN system are proposed. Specifically, a transmitter generates and transmits an EHT PPDU to a receiver through a 320 MHz band from which an 80 MHz band is punctured. The EHT PPDU includes a legacy preamble and an EHT field. The legacy preamble includes an L-STF and an L-LTF. The legacy preamble is generated by applying a first phase rotation value. The first phase rotation value is obtained on the basis of a second phase rotation value and a third phase rotation value. The second phase rotation value is a phase rotation value that repeats a phase rotation value defined for the 80 MHz band in an 802.11ax system. The third phase rotation value is a phase rotation value defined in unit of the 80 MHz band in the 320 MHz band on the basis of an optimal PAPR of the L-STF and L-LTF. The first phase rotation value is [1 1 −1 −1 −j −j j j 1 1 −1 −1 −j −j j j].

    Abstract: Proposed are a method and apparatus for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives a PPDU from a transmission STA via a broadband and decodes the PPDU. The PPDU includes a control field and a data field. When the broadband is a band of 320/160+160 MHz including a primary channel of 160 MHz and a secondary channel of 160 MHz, the data field is received via a first multiple RU in which a 996-RU and a 484-RU are aggregated. The first multiple RU is allocated within the primary channel of 160 MHz or the secondary channel of 160 MHz.

    Abstract: An example according to the present specification relates to a technique for configuring a preamble in a wireless LAN (WLAN) system. A transmitting STA may generate and transmit an EHT PPDU. The EHT PPDU may comprise an L-SIG field, an RL-SIG field, a first control field, and a second control field. A result of “modulo 3 operation” for a length field value of the L-SIG field may be set to “0.” The RL-SIG field may be configured to be the same as the L-SIG field. The first control field may comprise 3-bit information on the version of a PPDU, 6-bit information on a BSS color, and 7-bit information on TXOP.

    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: The present disclosure relates to a data transmission apparatus and method using a polarized antenna in a wireless AV system, and a data reception apparatus and method. The present specification provides a method for performing polarization alignment for a downlink on the basis of reciprocity, a method for performing polarization alignment for an uplink, and a method for performing polarization alignment independently for each DMG antenna when one data transmission apparatus or one data reception apparatus uses multiple DMG antennas. Optimal MIMO performance can be guaranteed by aligning polarization between multiple antennas of the data transmission apparatus and the data reception apparatus in the wireless AV system, the polarization alignment for a downlink or an uplink may be selectively performed on the basis of reciprocity, and polarization distortion can be reduced through the independent polarization alignment between each DMG antenna.
