1. A sleep controller for use in a receiver within a wireless transceiver, the controller comprising:
- a sleep control logic communicatively coupled to a processor to receive therefrom a timeline indicative of power reduction periods produced by the processor,said sleep control logic configured to shut down and power up at least some components of the receiver during power reduction periods in accordance with the time line independent of the processor,wherein a portion of the at least some components of the receiver are shut down in accordance with the timeline upon completion of a portion of signal processing of a communication signal received by the receiver,wherein the signal processing includes performing Fast Fourier Transform (FFT) processing to identify a burst snooze tag in an FFT descriptor of the signal.

Abstract
Disclosed are apparatus and methods for control of sleep modes in a transceiver or receiver. In particular, a transceiver is disclosed including a processor configured to determine timing information concerning sleep periods for at least a portion of components within the transceiver. The transceiver also includes a sleep control logic coupled to the processor to receive information concerning sleep periods from the processor and configured to effect shutting down of the at least a portion of the components of the transceiver during power reduction periods independent of the processor.
