Abstract

Embodiments of methods for optimizing power savings in a wireless device by maintaining sleep in sub-frames of an extended Listen Window, in an I.E.E.E. 802.16m communication system. In one embodiment, the Listen Window is extended into the Sleep Window, wherein at least one sub-frame remains designated for sleep. The power savings may be used when HARQ retransmissions are scheduled or for VoIP transmissions and so forth.
