    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: The present specification proposes a method for configuring a trigger frame that can be applied to a next-generation Wireless LAN (WLAN) system and an apparatus using the method. As an example, the trigger frame of the present specification may set a bandwidth for a trigger-based (TB) PPDU of up to 320 MHz. As another example, the trigger frame of the present specification may set the format of the TB PPDU transmitted through a primary bandwidth. As another example, the trigger frame of the present specification may trigger an aggregated PPDU (A-PPDU).

    Abstract: The present document relates to a method and device for an Access Point (AP) to transmit ACK/NACK signals for MU (Multi-User) transmission data of a plurality of stations (STA) in a wireless LAN (WLAN) system. To this end, the method and device are characterized in that a STA responds to a trigger frame received from an AP, transmits data to the AP through an MU access technique, and sets an ACK policy value for data transmitted on the basis of the trigger frame to another value other than a first ACK policy value requesting an ACK signal transmission on the basis of a block ACK request.

    Abstract: A method for an STA to transmit or receive a frame in a WLAN, according to one embodiment of the present invention, comprises the steps of: receiving a first HARQ trigger frame that triggers transmission of an A-PHDU into which PHDUs that are PHY data transmission units for a HARQ process are combined; transmitting at least one PHDU within the A-PHDU on the basis of the first HARQ trigger frame at the timing designated for the STA; and retransmitting the at least one PHDU or transmitting a new PHDU according to reception of a second HARQ trigger frame, wherein the first HARQ trigger frame includes timing offset information between the STA and another STA transmitting the PHDU within the A-PHDU, and the STA may determine the timing designated for the STA by using the timing offset information.
