Abstract
A method for power saving in a wireless local area network and a device using the same are provide. The device wakes up at a start of a wakeup time and receives a wakeup physical layer protocol data unit (PPDU) during the wakeup time. The device updates a timing synchronization function (TSF) timer in accordance with a value in the wakeup PPDU.
Claims15
A method for power saving in a wireless local area network, the method performed by a station comprising:
- waking up at a start of a wakeup time;
- during the wakeup time, receiving a wakeup physical layer protocol data unit (PPDU), the wakeup PPDU including a timing synchronization function (TSF) field indicating a value of a TSF timer;
- and
- updating the TSF timer based on the TSF field,
- wherein the wakeup PPDU includes a legacy-Short Training field (L-STF), a legacy-Long Training field (L-LTF) 320, a legacy-SIGNAL field (L-SIG), a wakeup physical (PHY) header and wakeup information, and
- wherein the wakeup PHY header includes a sync field and a receiver ID field, the sync field indicating a start of the wakeup PHY header, the receiver ID field indicating the station to receive the wakeup PPDU.

A device for power saving in a wireless local area network, the device comprising:
- a transceiver configured to receive and transmit radio signals;
- and
- a processor coupled with the transceiver and configured to:
- wake up at a start of a wakeup time;
- during the wakeup time, control the transceiver to receive a wakeup physical layer protocol data unit (PPDU), the wakeup PPDU including a timing synchronization function (TSF) field indicating a value of a TSF timer;
- and
- update the TSF timer based on the TSF field,
- wherein the wakeup PPDU includes a legacy-Short Training field (L-STF), a legacy-Long Training field (L-LTF) 320, a legacy-SIGNAL field (L-SIG), a wakeup physical (PHY) header and wakeup information, and
- wherein the wakeup PHY header includes a sync field and a receiver ID field, the sync field indicating a start of the wakeup PHY header, the receiver ID field indicating the station to receive the wakeup PPDU.
