Abstract: Disclosed are a method and apparatus for transmitting a frame. A method for transmitting a frame in a wireless LAN comprises the steps of: an STA receiving an uplink transmission trigger frame from an access point (AP), wherein the uplink transmission trigger frame triggers the transmission of an uplink frame of an STA on an overlapping time resource, and triggers the transmission of one other uplink frame of at least one other STA; the STA transmitting the uplink frame to the access point (AP) through an allocated uplink transmission resource; and the STA performing a backoff process based on channel access parameters, which have been determined according to the success of the uplink frame transmission.

Abstract: Disclosed are a method and apparatus for power saving mode-based operation in a wireless LAN. A method for power saving mode-based operation in a wireless LAN can comprise the steps of: an STA performing an initial configuration procedure for configuring a TIM-based power saving mode and an AP; the STA being converted from a doze state to an awake state, on the basis of a transmission period of a beacon frame, by operating in the TIM-based power saving mode on the basis of the initial configuration procedure, and thereby receiving a first downlink frame from the AP; the STA receiving from the AP operation mode configuration information indicating conversion from the TIM-based power saving mode to an active mode; and the STA receiving, on the basis of the active mode, a second downlink frame from the AP.

Abstract: The present document relates to a wireless communication system and, more particularly, to a method for establishing a wireless channel by an AP in a high-density wireless LAN system and to an apparatus therefor. The AP configured for this purpose can establish a primary channel and one or more secondary channels, establish one or more downlink oriented channels into one or more secondary channels, but without the one or more downlink oriented channels overlapping the primary channel of an adjacent basic service set (BSS), and transmit, to a station connected to the AP, the frame including establishment information on the established one or more downlink oriented channels.

Abstract: The present document relates to a method for transmitting an acknowledgement/negative acknowledgement (ACK/NACK) signal for transmission data of a plurality of stations (STAs) by an access point (AP) in a wireless LAN (WLAN) system, and an apparatus therefor. To this end, the AP transmits a trigger frame to the plurality of STAs, and on receiving data from the plurality of STAs in response to the trigger frame, transmits ACK/NACK signals for the data received from the plurality of STAs through a multiuser block ACK frame (M-BA frame). Here, the M-BA frame includes ACK/NACK signals for STAs, the number of which is determined so as not to exceed a specific transmission unit time, among the ACK/NACK signals for the plurality of STAs, and the AP additionally transmits ACK/NACK signals to one or more STAs, to which ACK/NACK signals have not been transmitted through the M-BA, among the plurality of STAs.
