Abstract: A method and a device for transmitting and receiving a PPDU on the basis of an FDD in a wireless LAN system are presented. Particularly, an AP transmits a trigger frame to a first STA and a second STA. The AP transmits a first downlink (DL) PPDU to the first STA on the basis of the trigger frame. The AP transmits a second DL PPDU to the second STA on the basis of the trigger frame. The AP receives a first uplink (UL) PPDU from the second STA on the basis of the trigger frame. The trigger frame includes bandwidth information of a primary channel and a secondary channel. The first DL PPDU is transmitted through the primary channel. The second DL PPDU and the first UL PPDU are transmitted through the secondary channel. The first and second DL PPDU are simultaneously transmitted. The first UL PPDU is received after a preset period after the second DL PPDU is transmitted.

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 an apparatus for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives a PPDU from a transmission STA through a first band and decodes the PPDU. The PPDU includes a control field and a data field. The first band is an 80 MHz band including first and second 20 MHz subchannels and a first 40 MHz subchannel. When the first 20 MHz subchannel is punctured, the second 20 MHz subchannel includes a first multi-RU in which first and second 26-RUs, 52-RUs, and 106-RUs are aggregated. The first 40 MHz subchannel includes a 484-RU. The data field is received through a second multi-RU in which the first multi-RU and the 484-RU are aggregated.

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: In a wireless local area network (LAN) system, a station (STA) can generate a plurality of long training field (LTF) symbols used for a plurality of streams including first to fourth streams. The first to fourth streams use different LTF sequences, and the LTF sequences used by the first to fourth streams may be multiplied by the same element of a P matrix. The STA may include a step for transmitting a PHY protocol data unit (PPDU) including the plurality of LTF symbols.

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: In a wireless local area network (WLAN) system, a first station (STA) may transmit first information related to a maximum value of a hybrid automatic repeat request (HARQ) index supported by the first STA, and second information related to a time limit related to the HARQ index. The HARQ index may be used for an HARQ operation of the first STA, and the time limit may be used for a maximum storage time of an HARQ buffer related to the HARQ index. The first STA may perform an association with a second STA on the basis of the first information and the second information.
