摘要： A method and a device for positioning a NAN terminal in a wireless LAN system are provided. A first station receives, through a service discovery frame during a preset discovery window, allocation information of an available window for reporting a location estimate value of the first station, location information of a second station located within a distance of one hop from the first station, and location information of a third station located within a distance of at least one hop from the second station. The first station determines the location estimate value of the first station on the basis of the location information of the second station and the location information of the third station. The first station reports the location estimate value of the first station during a section indicated by the allocation information of the available window.

摘要： 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.

摘要： The present document relates to a power reduction mode operation of a STA in a wireless communication system. To this end, during the STA's power saving mode operation, the TIM (traffic indication map) reception, the PS poll signal transmission, and the data reception are performed through one of a downlink oriented channel and a general channel distinguished from the downlink oriented channel, and the STA may previously acquire information on whether the TIM reception, the PS poll signal transmission, and the data reception are performed through one channel of the downlink oriented channel and the general channel.

摘要： A method and an apparatus for receiving a downlink frame in a wireless LAN are disclosed. The method and apparatus for receiving a downlink frame in a wireless LAN may comprises the steps of: an STA receiving from an AP a downlink frame via a downlink dedicated channel; and the STA transmitting to the AP a response frame related to the downlink frame via the downlink dedicated channel. The downlink dedicated channel allows transmission only of a contention-free downlink frame by the AP and a response frame by the STA, and restricts transmission of an independent uplink frame by the STA, wherein the independent uplink frame may be an uplink frame other than a response frame among uplink frames that are transmitted from the STA to the AP.
