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 disclosure proposes a method and apparatus for configuring a field for indicating transmission of an A-PPDU and a bandwidth of an A-PPDU in a wireless LAN system. Specifically, a receiving STA receives an A-PPDU from a transmitting STA. The receiving STA decodes the A-PPDU. The A-PPDU comprises an HE PPDU for a primary 160 MHz channel and an EHT PPDU for a secondary 160 MHz channel. The EHT PPDU comprises first and second U-SIG fields. The first U-SIG field comprises a first BW field. The second U-SIG field comprises a Validate field. The Validate field comprises information indicating that the A-PPDU has been transmitted. The first BW field comprises information on a bandwidth of the A-PPDU and a bandwidth of the EHT PPDU.
