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.

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.

Abstract: A method and an apparatus for triggering uplink data in a wireless LAN are disclosed. A method for receiving uplink data in a wireless LAN may comprise: a step in which an access point (AP) transmits a trigger frame for random connection; and a step in which the AP receives at least one buffer status report frame from at least one STA on a random connection transmission opportunity (TXOP) which is set on the basis of the trigger frame for random connection, wherein the random connection TXOP is allocated for a channel access attempt for transmitting the buffer status report frame of each of a plurality of non-specific STAs, and each of the at least one STA may be an STA which succeeds in the channel access among the plurality of non-specific STAs.

Abstract: The present specification suggests a signal processing method for changing an operating mode to configure a PPDU in a wireless local area network (WLAN) system. Specifically, a first station receives indication information indicating a change in operating mode that indicates a number of spatial streams and a receiving channel bandwidth that are supported by a second station from the second station. The first station transmits a block acknowledgement (BA) in response to the indication information, the BA including a first delay required bit. The first station defers applying the indication information so that the indication information is not applied when the first delay required bit is a predetermined value.
