Direct link setup method in tunneled direct link setup wireless network and station supporting the method

A station for supporting Tunneled Direct Link Setup (TDLS) in a wireless local access network, the station comprising:

• a processor configured to generate and process frames;
• and
• a transceiver operably connected to the processor and configured to transmit and receive the frames for the processor,
• wherein the station is configured to:
• associate a Basic Service Set (BSS) which includes an Access Point (AP),
• transmit 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 between the station and the intended peer station, the TDLS setup request frame including a link identifier identifying the TDLS direct link, the link identifier including a BSSID field, a transmitter address field and a receiver address field, the BSSID field being set to a BSSID of a BSS to which the station is associated, the transmitter address field being set to a medium access control (MAC) address of the station, the receiver address field being set to a MAC address of the intended peer station,
• receive a TDLS setup response frame including a status code field through the AP from the intended peer station in response to the TDLS setup request frame, the status code field indicating whether or not the request by the TDLS setup request frame is accepted, and
• transmit a TDLS setup confirm frame including the link identifier through the AP to the intended peer station in response to the TDLS setup response frame,
• wherein the TDLS setup confirm frame includes high throughput operation information.
