Abstract: Disclosed are a method and a device for operation based on a power save mode in a WLAN. The method for operation based on a power save mode in a WLAN may comprise steps in which: an STA receives an ACK frame from an AP in response to a PS-poll frame; after receiving the ACK frame, the STA receives a different BSS PPDU before receiving a downlink frame from the AP; and the STA determines whether or not to switch to a doze state from an awake state on the basis of the reception strength of the different BSS PPDU.

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.

Abstract: An association method for data transmission between devices in a neighbor awareness network (NAN), and a device using the same are provided. A first NAN device transmits, to a second NAN device, a service discovery frame having a service identifier (ID) and association interval information, and transmits an authentication request for requesting authentication at a time indicated by the association interval information.

Abstract: Disclosed are a method and an apparatus for power save mode operation on the basis of a frame transmitted from another BSS in a wireless LAN. A method for operating an STA in a wireless LAN in a power save mode comprises: a step in which the STA receives a beacon frame from an AP, the beacon frame comprising a TIM element indicating downlink data pending in the STA; a step in which the STA transmits a PS-poll frame to the AP in response to the beacon frame; a step in which the STA receives, from the AP, an ACK frame transmitted by the AP in response to the PS-poll frame; and a step in which the STA determines the operation of the another BSS in a TXOP power save mode on the basis of the ACK frame.
