Abstract
A first wireless communication device may be operable to communicate with one or more other wireless communication devices to schedule access to a medium that is shared by the first wireless communication device and the one or more other wireless communication devices. After one or more medium access periods are scheduled for the first wireless communication device, the first wireless communication device may transmit data onto the medium upon receiving a medium reservation message which designates the first wireless communication device during the one or more medium access periods scheduled for the first wireless communication device. One or more portions of the first wireless communication device may be configured to operate in a first mode during medium access periods scheduled for the first wireless communication device, and configured to operate in a power-saving mode at times other than the medium access periods scheduled for the first wireless communication device.
