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: The present disclosure proposes a method and device for transmitting capability information about a reception STA in a wireless LAN system. Specifically, the reception STA generates and transmits capability information about the reception STA to a transmission STA. The capability information about the reception STA includes an EHT Capabilities element. The EHT Capabilities element includes a Supported EHT-MCS And NSS Set field. The Supported EHT-MCS And NSS Set field includes first to third sub-fields. When allocated to a first transmission bandwidth regardless of the bandwidth in which the reception STA operates, the first sub-field includes information about the number of maximum spatial streams that the reception STA can transmit and receive in each MCS. When the reception STA operates in the 5 GHz and 6 GHz bands, the first transmission bandwidth is 20 MHz, 40 MHz or 80 MHz. When the reception STA operates in the 2.6 GHz band, the first transmission bandwidth is 20 MHz or 40 MHz.

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.
