Methods And Apparatus For Reducing Power Consumption In CDMA Communication Device
First Claim
Patent Images
1. A method in a code division multiple access (CDMA) communication device comprising the acts of:
- operating in a voice call during which voice or audio information is communicated in frames over forward and reverse links;
causing a transmitter to enter and be maintained in a low power state during a voice inactivity period of the voice call, for stopping transmission of lowest rate frames that would otherwise be sent during the voice inactivity period; and
causing the transmitter to be exited from the low power state for resuming transmission for the voice call.

Abstract
Methods and apparatus for reducing power consumption of a code division multiple access (CDMA) communication device are described. The CDMA communication device operates in a voice call during which voice or audio information is communicated in frames over forward and reverse links. During voice inactivity periods of the voice call, a transmitter of the CDMA communication device is controlled to enter and be maintained in low power states, for stopping transmission of lowest rate frames that would otherwise be sent during the voice inactivity period.

9. A code division multiple access (CDMA) communication device, comprising:
-
a receiver; a transmitter which includes a power amplifier (PA); a processor coupled to the receiver and the transmitter; the processor being adapted to; operate the receiver and the transmitter in a voice call during which voice or audio information is communicated in frames over forward and reverse links; cause the transmitter to enter and be maintained in a low power state during a voice inactivity period of the voice call, for stopping transmission of lowest rate frames that would otherwise be sent via the transmitter during the voice inactivity period; and cause the transmitter to be exited from the low power state for resuming transmission for the voice call. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. A code division multiple access (CDMA) communication system, comprising:
-
a base station adapted to communicate in accordance with CDMA communications; a portable electronic device adapted to communicate with the base station in accordance with CDMA communications; the portable electronic device being adapted to operate in a voice call during which voice or audio information is communicated in frames over forward and reverse links with the base station; the portable electronic device being further adapted to, in response to identifying that there is no voice activity at the portable electronic device during the voice call;
cause a transmitter to enter and be maintained in a low power state during a voice inactivity period of the voice call, for stopping transmission of lowest rate frames that would otherwise be sent from the portable electronic device during the voice inactivity period; andthe portable electronic device being further operative to cause the transmitter to be exited from the low power state for resuming transmission for the voice call. - View Dependent Claims (19, 20, 21, 22)
