Abstract:
A Tunneled Direct Link Setup (TDLS) establishment method. The method includes associating a Basic Service Set (BSS) which includes an Access Point (AP); transmitting a TDLS setup request frame through the AP to an intended peer station, the TDLS setup request frame requesting to establish a TDLS direct link, the TDLS setup request frame including a link identifier, the link identifier including a BSSID field, a transmitter address field and a receiver address field, the BSSID field being set to a BSSID, the transmitter address field being set to a medium access control (MAC) address of the TDLS initiator, the receiver address field being set to a MAC address of the intended peer station; receiving a TDLS setup response frame including a status code field; and transmitting a TDLS setup confirm frame including the link identifier. The TDLS setup confirm frame includes high throughput operation information.

Disclosed are a method and a device for transmitting data unit in a WLAN. A method for transmitting data unit in a WLAN comprises: a step of an STA generating a PPDU; and a step of the STA transmitting the PPDU to an access point (AP), wherein the PPDU comprises a first field and a second field, wherein the first field is transmitted on the basis of a first IFFT and the second field is transmitted on the basis of a second IFFT.
Abstract:
Disclosed is a method and apparatus for transmitting data in a non-licensed band. The method of transmitting downlink data in the non-licensed band may comprise the steps of: generating, by a base station, downlink data and transmitting the downlink data to a terminal through a downlink subframe. The downlink data may comprise wireless LAN preamble, PDCCH data, and PDSCH data. The wireless LAN preamble may comprise information on time resources for communication between the base station and the terminal, and the PDCCH data may comprise control data for the terminal. Also, the PDSCH data may comprise traffic data for the terminal.
Abstract:
The present invention relates to a wireless communication system, and more specifically disclosed are a method and a device for transceiving a frame comprising a partial association identifier (PAID) in the wireless communication system. A method for transmitting the frame in a station (STA) of the wireless communication system according to one embodiment of the present invention comprises a step of transmitting the frame comprising a PAID field, and: if the frame is a frame other than a control frame when the frame is an uplink frame to be transmitted to an access point (AP), the value of the PAID field can be set as a value other than 0, which is calculated on the basis of BSSID (Basic Service Set ID) of the AP; and if the frame is the control frame when the frame is the uplink frame, the value of the PAID field can be set as 0.

Abstract:
Disclosed are a method and an apparatus for sounding in a wireless communication system. A method for sounding in a wireless local area network (WLAN) may comprise: a step of receiving, by an STA, an NDPA frame from an AP; a step of receiving, by the STA, an NDP frame on the basis of identification information included in the NDPA frame; and a step of transmitting, by the STA, channel state information determined on the basis of the NDP frame to the AP, wherein the NDPA frame may be demodulated on the basis of a first FFT and the NDP frame may be demodulated on the basis of a second FFT.
Abstract:
The present invention relates to a wireless communication system and, more specifically, to a method and a device for scanning multiple bands in a wireless LAN system. The method by which a station (STA) scans in a wireless communication system, according to one embodiment of the present invention, comprises the steps of: transmitting a first frame to a first access point (AP); and receiving a second frame responding to the first frame from the first AP, wherein the first frame includes service set identifier (SSID) information and information on an operation class supported by the STA, and the second frame can include information for indicating whether or not to filter and information on a second AP.
Abstract:
The present invention relates to a wireless communication system and, more particularly, to a method and device for transmitting and receiving a short frame fragment in a wireless LAN system. A method of transmitting a fragment frame by means of a station (STA) in a wireless LAN system according to an embodiment of the present invention includes the steps of transmitting a plurality of fragment frames generated from a frame; and receiving a response frame for one or more of the fragment frames, wherein a response indication field of fragment frames excluding the last fragment frame from among the plurality of fragment frames may be set as a value representing the maximum length.
Abstract:
Disclosed are a method and an apparatus for recovering data units in a wireless communication system. The method of recovering data units in a wireless LAN comprises the steps of: determining a channel state of at least one secondary channel band for a predetermined time after an STA has failed to transmit a first PPDU; and transmitting, at the STA, a second PPDU through a recovery channel band determined on the basis of the channel state, wherein the first PPDU is data transmitted through a primary channel and at least one secondary channel, and the recovery channel band may include, from among the primary channel band and at least one secondary channel, a secondary channel that is in an idle state.
