Patent ID: 7983204

Claim:
A wireless communication device comprising: a housing; a controller coupled to the housing, the controller configured to control the operations of the wireless communication device; memory coupled to the controller; a transceiver coupled to the controller, the transceiver configured to send and receive wireless signals; the receive signal includes at least a control channel and a packet data channel, the control channel being configured to provide the modulation and encoding and/or decoding information necessary to process a subsequent packet of data received by the transceiver or in preparation for transmission by the transceiver; a monitoring module for monitoring the control channel and controlling a dynamic scaling module, the monitoring module reads a parameter field from the control channel which is used to determine that the data message has certain processing needs meeting a certain threshold; the dynamic scaling module configured to provide energy savings by varying the voltage and frequency of a controller, substantially real-time, according to the processing needs determined by the monitoring module, including: (i) a performance mode including a performance voltage and performance frequency when the certain threshold is met; and (ii) a default mode including a default voltage and default frequency when the certain threshold is not met.
