Abstract: The present document relates to a method and device for an Access Point (AP) to transmit ACK/NACK signals for MU (Multi-User) transmission data of a plurality of stations (STA) in a wireless LAN (WLAN) system. To this end, the method and device are characterized in that a STA responds to a trigger frame received from an AP, transmits data to the AP through an MU access technique, and sets an ACK policy value for data transmitted on the basis of the trigger frame to another value other than a first ACK policy value requesting an ACK signal transmission on the basis of a block ACK request.

Abstract: In the wireless LAN system, the station STA receives a frame and updates a corresponding Inter-BSS Network Allocation Vector (NAV) or Intra-BSS NAV according to whether the frame is an Inter-BSS (Basic Service Set) frame or an Intra-BSS frame. If the received frame cannot be distinguished from the Inter-BSS frame or the Intra-BSS frame, it updates the Inter-NAV, and after receiving the frame that cannot be distinguished from the Inter-BSS frame or the Intra-BSS frame, it receives the CF-End frame, and then the corresponding NAV is reset.

Abstract: Disclosed is a power saving method for a station (STA) in a mobile communication system. On receiving a trigger frame from an access point (AP), a STA transmits a physical protocol data unit (PPDU) to the AP through a multi-user scheme, in response to the trigger frame, wherein the trigger frame includes subsequent scheduling information for each STA. Accordingly, the STA may transit to a doze state on the basis of the subsequent scheduling information for each STA.

Abstract: A method for a station (STA) not having an association identifier (AID) allocated thereto transmitting a signal in a wireless LAN system, according to one embodiment of the present invention, comprises the steps of: transmitting a first frame through at least one resource among resources indicated by a trigger frame; and receiving a multi-STA block Ack (M-BA) frame as a reply to the first frame, wherein, if in the M-BA frame a MAC address of the STA that is different from a first information is detected from at least a part of a first field reserved for the first information, an N-bit of a second field preceding the first field is set as a temporary AID of the STA.
