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 transmitting STA may generate and transmit an EHT PPDU. The EHT PPDU may include an L-SIG field, an RL-SIG field, and a control field. A result of “modulo 3 operation” to a length field value of the L-SIG field may be set to “0”. The RL-SIG field may be configured the same as the L-SIG field. The control field may include 3-bit information relating to a version of a PPDU.

Abstract: The present disclosure is related to a Long Training Field (LTF) signal used in a wireless local area network (WLAN) system. The LTF signal may be generated by a transmitting station (STA) and received by a receiving STA. The LTF signal may be included in a physical protocol data unit (PPDU), and the PPDU may be transmitted an 80 MHz band. The LTF sequence may include at least two parts, i.e., a first LTF sequence and a second LTF sequence.

Abstract: Disclosed are a method and an apparatus for generating an STF signal usable in a wireless LAN system. The STF signal is included in a field used to improve AGC estimation of a MIMO transmission. A portion of the STF signal is used to transmit an uplink, and can be used for uplink MU PPDUs transmitted from a plurality of STAs. The STF signal that is disclosed, for example, is used for a 40 MHz band or an 80 MHz band, is desirably usable for the 40 MHz band, and can be generated based on a sequence in which a predetermined M sequence is repeated. The predetermined M sequence can be a binary sequence of which the length is 15 bits.

Abstract: Proposed are a method and a device 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 legacy preamble and a first and a second signal field. The legacy preamble and the first and second signal fields are generated on the basis of a first and a second phase rotation value. When the broadband corresponds to a 320 MHz band, the first phase rotation value is [1 −1 −1 −1 1 −1 −1 −1 −1 1 1 1 −1 1 1 1]. An element of the first phase rotation value is applied to each 20 MHz band of the 320 MHz band. An element of the second phase rotation value is applied to each subcarrier of the 320 MHz band.

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: Proposed are a method and device for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives a PPDU through a wide band from a transmission STA, and decodes the PPDU. The wide band is a 320/160+160 MHz band configured from a first band and a second band. When the first band is an 80 MHz band in which puncturing is performed in units of 20 MHz, the first band includes a first RU which is an aggregate of a 484RU and a 242RU. The second band is a 240 MHz band excluding the first band in the wide band, and includes a second RU which is an aggregate of three 996 RUs. The PPDU includes a control field and a data field. The data field is received via a first multi-RU which is an aggregate of the first and second RUs.

Abstract: Proposed are a method and a device for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives a PPDU through a broadband from a transmission STA, and decodes the PPDU. The broadband is a 320 MHz band or a (160+160) MHz band. The PPDU includes an STF signal. The STF signal is generated on the basis of a first STF sequence for the broadband. The first STF sequence is obtained by applying a phase rotation to a sequence in which a second STF sequence for a 80 MHz band is repeated. The first STF sequence is a sequence in which a preconfigured M sequence is repeated, and is defined by a formula {M−1 −M 0 −M −1 M 0 M −1 −M 0 −M −1 M 0 −M 1 M 0 M 1 −M 0 −M 1 M 0 M 1 −M}*(1+j)/sqrt(2). A first preamble puncturing pattern includes all patterns of a band obtained by puncturing a 20 MHz band in the 320 MHz band or the (160+160) MHz band.

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.
