    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 performing retransmission in a wireless LAN system to which transmission opportunity (TXOP) sharing is applied, and a device therefor. To this end, a station transmits an initial transmission frame including primary access category (AC) information and secondary access category (AC) information; and when there is no response to the secondary AC information of the initial transmission frame, reconfigures a back-off timer value for the secondary AC information and retransmits the secondary AC information according to the reconfigured back-off timer value.

    Abstract: The present document relates to a wireless communication system and, more particularly, to a data transmission and reception operation between an AP and an STA in a high density wireless LAN system. To this end, the STA receives a beacon frame including downlink frame transmission interval information from the AP, and receives data from the AP through a time interval corresponding to the downlink frame transmission interval information, wherein the data reception from the AP through the time interval corresponding to the downlink frame transmission interval information is processed at a higher priority than the data transmission toward the AP.

    Abstract: Disclosed are a method and an apparatus for operating based on a power save mode in a wireless LAN. The method for operating based on the power save mode in a wireless LAN may comprise the steps of: switching an STA from a sleep mode to an active mode after the STA has been switched to a power save mode based on a listen interval, to receive a first beacon frame transmitted by an AP; monitoring a frame for the STA transmitted by the AP until a timer started when the STA is switched to the active mode expires, when the first beacon frame indicates data buffered for the STA; and switching the STA to the sleep mode after the timer expires, wherein the timer can be reset when the frame is transmitted.
