Abstract: A method and a device for receiving a PPDU in a wireless LAN system are presented. Specifically, a reception STA receives a PPDU from a transmission STA through a broadband 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 a broadband. The first STF sequence is a sequence of which a phase rotation is applied to a sequence in which a second STF sequence is repeated. The second STF sequence is an STF sequence for a 80 MHz band defined in an 802.11ax wireless LAN system. If the broadband is a 320 MHz band, the first SFT sequence is a sequence in which preset sequence M is repeated, and is defined to be the same as {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)).

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 broadband is a 320 MHz band or a 160+160 MHz band. The PPDU includes a first field and a second field. The first field includes an L-LTF. The first field is generated on the basis of a first phase rotation value. The first phase rotation value is [1 −1 −1 −1 −j j j j 1 −1 −1 −1 −j j j j]. One element of the first phase rotation value is a phase rotation value applied to each 20 MHz band of the 320 MHz band or the 160+160 MHz band.

Abstract: Proposed are a method and device for performing sensing in a wireless LAN system. Specifically, a transmission STA generates a frame. The transmission STA transmits the frame to a reception STA in a 60 GHz band. The frame includes an EDMGHeader-A field. A reserved bit of the EDMG-Header-A field includes a packet classification descriptor. The packet classification descriptor includes information indicating that the frame is a sensing frame used for sensing.

Abstract: A receiving STA can receive a first PPDU including a first data block and a second data block in a wireless local area network system according to various embodiments. The first data block and the second data block can be configured by a first index. Afterward, the receiving STA can transmit a retransmission request signal for the first data block. The receiving STA can receive the first data block again. Then, the receiving STA can combine the first and second data blocks configured by the first index.

Abstract: Disclosed are a method and an apparatus for transmitting and receiving protocol data unit (PDU)-related information in a wireless LAN system. The method by which a first station (STA) transmits an aggregate-medium access control (MAC) protocol data unit (PDU) (A-MPDU) in a wireless LAN system, according to an embodiment of the present disclosure, may comprise the steps of: receiving, from a second STA, one or more of first information, second information, and third information related to the maximum length for the A-MPDU; and transmitting, to the second STA, an A-MPDU having a length less than or equal to the maximum length for the A-MPDU, which is derived from a first type physical layer PDU (PPDU) on the basis of the first information, the second information, and the third information.

Abstract: Proposed are a method and device for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives the PPDU from a transmission STA through a wideband and decodes the PPDU. The PPDU includes an STF signal. The STF signal is generated on the basis of a first STF sequence for the wideband. When the wideband is a 320 MHz band, the first STF sequence is a sequence including a M sequence and is defined as {M −1 M −1 −M −1 M 0 −M 1 M 1 −M 1 −M 0 M −1 M −1 −M −1 M 0 −M 1 M 1 −M 1 −M 0 −M 1 −M 1 M 1 −M 0 M −1 −M −1 M −1 M 0 −M 1 −M 1 −M 1 M 1 −M 0 M −1 −M −1 M −1 M}*(1+j)/sqrt(2).

Abstract: Proposed herein is a method and device for setting limited RUs and MRUs in a WLAN system. More specifically, a receiving STA receives a PPDU from a transmitting STA through a preset frequency band, and decodes the PPDU. The receiving STA is an STA operating only in a 20 MHz band. The PPDU includes a preamble and a data field. The data field is received through resources other than the first RU and the first MRU among the preset frequency band.
