Abstract: Provided are a method and device for receiving data in a wireless LAN system. Particularly, an STA transmits an operating band negotiation request frame to an AP by means of a first band supported by first and second RFs. The STA receives an operating band negotiation response frame from the AP by means of the first band as a response to the operating band negotiation request frame. The STA changes the first band supported by the second RF into a second band on the basis of the operating band negotiation request frame and the operating band negotiation response frame. The STA receives first data from the AP by means of the first band supported by the first RF and the second band supported by the second RF. The first data is transmitted by means of a multi-band in which the first band and the second band are combined.

Abstract: A method and a device for receiving uplink data in a WLAN system are proposed. Specifically, an AP transmits a beacon frame to a first STA or a second STA. The AP receives uplink data from the first STA or the second STA based on the beacon frame. The beacon frame includes information about a transmission mode for the uplink data for each channel in a first band and each channel in a second band. The uplink data is transmitted based on contention when the information about the transmission mode for the uplink data is set to a first value. The uplink data is transmitted based on scheduling when the information about the transmission mode for the uplink data is set to a second value.
