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

摘要

Provided are a Tunneled Direct Link Setup (TDLS) establishment method for a TDLS initiator and a station supporting the establishment method. In the establishment method, a requesting Non-AP QSTA transmits a TDLS setup request frame via an access point (AP) to an intended peer Non-AP QSTA. And, the requesting Non-AP QSTA receives a TDLS setup response frame via the AP from the intended peer station in response to the TDLS setup request frame. And, the requesting Non-AP QSTA transmits a TDLS setup confirm frame via the AP to the intended peer station in response to the TDLS setup response frame.

1. A Tunneled Direct Link Setup (TDLS) establishment method for a TDLS initiator, the method comprising:
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 between the TDLS initiator 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 TDLS initiator is associated, the transmitter address field being set to the TDLS initiator's medium access control (MAC) address, the receiver address field being set to the intended peer station's MAC address; and receiving 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, wherein if the status code field indicates acceptance to the request,
the BSSID of the BSSID field in the link identifier matches the BSSID of the BSS to which the intended peer station is associated,the TDLS setup response frame further includes the link identifier, andthe method further comprises transmitting 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 if the BSSID of the BSSID field in the link identifier of the TDLS setup request frame does not match the BSSID of the BSS to which the intended peer station is associated, the status code field indicates the request is rejected, wherein the TDLS setup confirm frame includes a high throughput operation information including a channel width and channel position information, and wherein the channel width is wider than 20 MHz.
