Patent ID: 8767600

Claim:
A method for transmission in a wireless local area network, the method comprising: setting up a tunneled direct link setup (TDLS) direct link between a first station and a second station by transmitting a TDLS setup request frame including a link identifier indicating the TDLS direct link via an access point (AP) to the second station, receiving a TDLS setup response frame including the link identifier from the second station via the AP in response to the TDLS setup request frame, and transmitting a TDLS setup confirm frame to the second station via the AP in response to the TDLS setup response frame; transmitting, by the first station, a TDLS peer Power Save Mode request frame including the link identifier via the AP to the second station in order to setup or change a wakeup schedule on the TDLS direct link, the TDLS peer Power Save Mode request frame including the wakeup schedule, wherein the TDLS peer Power Save Mode request frame is encapsulated in data frames, wherein the wakeup schedule is determined by power save mode parameters including an offset indicating a start of a first wakeup duration, a duration indicating a duration of a wakeup duration, and a periodicity indicating interval between two consecutive wakeup durations, wherein the power save mode parameters are used for the first station when the first station enters a power save mode; and receiving, by the first station, a TDLS peer Power Save Mode response frame from the second station in response to the TDLS peer Power Save Mode request frame, the response frame indicating whether the wakeup schedule in the TDLS peer Power Save Mode request frame is accepted or rejected by the second station, wherein the TDLS peer Power Save Mode response frame is encapsulated in data frames.
