Abstract: Proposed is a method and device for receiving data in a wireless LAN system. Specifically, an AP transmits a trigger frame to a first to a third station (STA) through a multi-band. The AP receives data from the first to third STAs on the basis of the trigger frame. In the multi-band, a first band to a third band are combined. The trigger frame includes a common information field and a first to a third user information field. When the first and second STAs are associated with the first band, the first user information field includes user information relating to the first and second STAs. When the second and third STAs are associated with the second band, the second user information field includes user information relating to the second and third STAs. When the third STA is associated with the third band, the third user information field includes user information relating to the third STA.

Abstract: Proposed is a method for determining transmission using a network allocation vector (NAV) in a wireless LAN system. Specifically, after a receiving device receives a trigger frame, which triggers an uplink multiple user transmission, from a transmitting device, whether to transmit an uplink physical layer protocol data unit (PPDU) corresponding to the trigger frame is determined using the NAV of the receiving device. In this case, if the NAV is established by an intra-basic service set (BSS) frame, whether to transmit the uplink PPDU is determined without taking the NAV into consideration.

Abstract: An ACK signal processing method that can be used in a wireless LAN system is proposed. Various information that can be used for a downlink MU PPDU for multiple receiving stations may be proposed, and, for example, in order to omit the re-transmission of the related art, information requesting an ACK or Block ACK corresponding to previously transmitted data may be included. If an immediate acknowledgement (ACK) frame fails to be received after the MU-PPDU is transmitted from the AP, a Block ACK may be requested. In this case, while a Block ACK is requested, a radio resource through which a Block ACK is delivered may be allocated.
