Control channel to enable a low power mode in a wideband wireless communication system

Abstract

A wireless multi-carrier communication system having designated control sub-channels that enable a receiving device to operate in a low power decoding mode. A sending device may send control or payload information via the control sub-channels. The receiving device operates in a low-power decoding mode to decode the control sub-channels, yielding the control or payload information. If the sending device has payload information directed to the receiving device that can not fit within the control sub-channels, it sends the information to the receiving device in one or more payload sub-channels. The receiving device operates in a second, generally higher power decoding mode to decode the payload sub-channels, yielding the payload information.
