    Abstract: A data transmission method of a station (STA) device in a wireless LAN system is disclosed. The data transmission method of an STA device, according to the present invention, comprises: a receiving step of receiving an uplink data frame from a first STA, wherein the uplink data frame includes first receiving operating mode information indicating a receiving operating mode to be changed by the first STA; and a transmitting step of transmitting an ACK frame for the uplink data frame, wherein the ACK frame includes mode change acceptance information indicating whether to accept or reject the change in the receiving operating mode according to the receiving operating mode information.

    Abstract: The present document relates to a wireless communication system and, more specifically, to a method for flexibly supporting resource allocation in a wireless LAN system, and a method and an apparatus for signal transmission using the same. To this end, a first STA configures a radio frame comprising: a signaling (SIG) field including control information; and a data field in which data can be transmitted via a discontinuous channel or a channel having a bandwidth size that is supported by a legacy system. When the first STA transmits the configured radio frame to a second STA, the SIG field preferably comprises: information about a full bandwidth in which data can be transmitted via the data field; and null indicator information indicating a channel region of the full bandwidth that is not used in data transmission, or used channel indicator information indicating a channel region of the full bandwidth that is used in data transmission.

    Abstract: In a wireless local area network system (WLAN), a method and an apparatus for reducing power consumption of a station (STA) comprising a wake-up receiver (WUR) and a WLAN transmitter/receiver are disclosed. To this end, an STA receives a wake-up packet (WUP) including a group-based identifier using the WUR when the WLAN transmitter/receiver is OFF, and switches the WLAN transmitter/receiver to be ON according to WUP information so as to perform WLAN communication using the WLAN transmitter/receiver, wherein one or more of switching the WLAN transmitter/receiver to be ON, and maintaining the ON state are indicated by a traffic indication map (TIM).

    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.
