Abstract: Disclosed herein is an operating method of a station (STA) in a wireless LAN (WLAN) system. The method includes receiving a downlink (DL) physical protocol data unit (PPDU) and sending an uplink (UL) PPDU as a response to the DL PPDU. The DL PPDU may include at least one MAC protocol data unit (MPDU) and the at least one MPDU may include a first high efficiency (HE) control field. The UL PPDU may include at least one MAC protocol data unit (MPDU) and the at least one MPDU may include a second high efficiency (HE) control field. The each of the first and second HE control fields corresponds to an HT control field and comprises a plurality of aggregated HE control subfield.

Abstract: According to various embodiments, a reception STA may receive a physical layer protocol data unit (PPDU) including a first signal field, a second signal field, and a data field. The PPDU may be configured to be transmitted to a single user. The second signal field may consist of one content channel, and the one content channel may be duplicated in a first bandwidth in units of a second bandwidth.

Abstract: The present specification proposes a technical feature for increasing a transmission range of a wireless LAN signal. The wireless LAN signal of the present specification, e.g. a transmission physical protocol data unit (PPDU), may be configured on the basis of a duplicate transmission mode. The transmission PPDU of the present specification may comprise a data unit duplicated in frequency. The data unit duplicated in frequency may be configured on the basis of a total bandwidth of the transmission PPDU. The transmission PPDU of the present specification proposes various training fields for the duplicated data unit.

Abstract: The present disclosure is related to a long training field (LTF) sequence for 320 MHz band transmission in a wireless local area network system. The main features comprise the steps of: generating a physical protocol data unit (PPDU); and transmitting the PPDU through a 320 MHz band, wherein the PPDU includes an LTF signal and the LTF signal is generated on the basis of an LTF sequence for the 320 MHz band. Therefore, the proposed LTF has improved effects such as increased bandwidth, an improved PHY layer protocol data unit (PPDU) structure, an improved sequence, and use of a hybrid automatic repeat request (HARQ) technique.

Abstract: The present disclosure proposes a method and an apparatus for transmitting capability information of a receiving STA in a wireless LAN system. Specifically, the receiving STA generates capability information of the receiving STA and transmits same to a transmitting STA. The capability information of the receiving STA includes an HE capabilities element and an EHT capabilities element. The HE capabilities element includes a supported channel width set field. The EHT capabilities element includes a supported EHT-MCS and NSS set field. The supported EHT-MCS and NSS set field includes first to fourth subfields. The first subfield includes information on the maximum number of spatial streams that the receiving STA can transmit and receive in each MCS when the receiving STA is a non-AP STA that operates only at 20 MHz and is allocated to a first transmission bandwidth.

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 is a method and device for receiving a PPDU in a wireless LAN system. Specifically, a receiving STA receives the PPDU from a transmitting STA through a broadband 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 broadband. The first STF sequence is obtained on the basis of a first preamble puncturing pattern of the broadband. When the broadband is a 320 MHz band, the first preamble puncturing pattern includes a pattern in which a 40 MHz or 80 MHz band is punctured in the broadband. The first STF sequence is a sequence including an M sequence and is defined 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).
