摘要： System and method of using an AP to individually controlling RTS/CTS duration thresholds for multiple STAs in a WLAN. In response to a STA's association request, the AP determines a duration threshold specific to the STA and encloses this information in an association request response for transmission to the STA. By using a broadcast frame, the AP may instruct multiple STAs to uniformly update their stored duration thresholds. For example, if the duration threshold field in the beacon frame is set to 0, the multiple STAs preserve their current duration thresholds; if the field is set to a non-zero value less than 1023, the multiple STAs all update their duration thresholds to the non-zero value; if this field is set to 1023, the multiple STAs disable the RTS/CTS transmissions. Based on a current threshold and pertinent policies, an STA can decide whether to initiate an RTS/CTS transmission sequence.

摘要： When channel switching to a channel in a white space band is performed through tunneled direct link setup (TDLS) in a wireless local area network (WLAN) system, it is confirmed whether or not a white space band between STAs is operable by directly including white space band performance between communication target STAs and device identifier information in a TDLS request/response message. Thus, one STA performs a channel availability query (CAQ) procedure in order to obtain available channel information, and a TDLS channel switching request/response message is exchanged by selecting a target channel in an available channel. Therefore, TDLS-based channel switching to a white space band is efficiently performed.

摘要： There is provided a protocol for a power save mode (PSM) in a direct link setup wireless network. In an aspect of the present invention, among first and second stations between which a direct link has been set up, the first station trying to enter the PSM transmits a request message, including schedule information necessary for communication with the second station, to the second station. The second station transmits a response message, including a status code indicating whether it accepts the schedule information or not, to the first station in response to the request message. If the status code indicates that the second station accepts the schedule information, the first station may transmit an MPDU whose power save bit is set to ‘1’ to the second station and then enter the PSM. However, if the status code indicates unacceptability, modified schedule information may be included in the response message.
