Abstract: Proposed are a method and an apparatus for receiving an MU PPDU in a wireless LAN system. Specifically, a receiving STA receives an MU PPDU from a transmitting STA. The receiving STA decodes the MU PPDU. The MU PPDU includes an LSIG field, an RL-SIG field, an HE-SIG field, and an EHT-SIG field. A first reserved bit of the L-SIG field includes information indicating that a first band in which the MU PPDU is transmitted is greater than 160 MHz. A second reserved bit of the HE-SIG field includes information relating to a second band in which the EHT-SIG field is transmitted or the size of the first band. The receiving STA includes an HE STA and an EHT STA.

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 through a broadband and decodes the PPDU. The PPDU includes a control field and a data field. When the broadband is a 320/160+160 MHz band including first to fourth 80 MHz sub-channels, the first 80 MHz sub-channel includes a first 996 RU, the second 80 MHz sub-channel includes a second 996 RU, the third 80 MHz sub-channel includes a third 996 RU, and the fourth 80 MHz sub-channel includes a first 484 RU. The data field is received through a first multiple RU in which the first to third 996 RUs and the first 484 RU are aggregated.

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: An example according to the present specification relates to a technique relating to a configuration of a preamble in a wireless LAN (WLAN) system. A reception STA can receive a PPDU. The reception STA can perform a modulo operation with respect to whether or not an L-SIG field is repeated and a value of a length field. The reception STA can determine the received PPDU as an EHT PPDU on the basis of the modulo operation with respect to whether or not the L-SIG field is repeated and the value of the length field.

Abstract: A transmission station (STA) of a wireless local area network system according to various embodiments can determine a first code rate and encode first data on the basis of a second code rate which is lower than the first code rate. The transmission STA can again generate second data on the basis of the first code rate and the encoded first data and transmit same.
