Abstract

A wireless communication device, such as an IEEE 802.11 station, receives an indication 615 that a second device, such as an IEEE 802.11 access point, has a data message intended for the first device 620. Low-power timing information is determined for the first device 630 and is included in a data request message sent to the second device 640. If a response to the data request message has been received 650, the wireless device enters a low-power state or mode corresponding to the low-power timing information 600. The low-power timing information may comprise discontinuous reception (DRX) pattern parameters indicating one or more durations that the wireless device will spend in a low-power state or mode and a non-low-power state or mode.
