Reducing power consumption by taking advantage of superior in-circuit duplexer performance

An apparatus comprising:

• a receiver;
• a transmitter that outputs a signal that passes in a signal path from an output of the transmitter to an input of the receiver;
• and
• a circuit that determines a transmitter-to-receiver isolation parameter based at least in part on a measurement of the signal, wherein the circuit sets a power consumption setting of a portion of the apparatus based on the determined transmitter-to-receiver isolation parameter.

A method comprising:

• (a) tuning a transmitter to output a signal in a transmit band;
• (b) tuning a receiver to receive in the transmit band;
• (c) using the receiver to determine a transmit band leakage power at an input of the receiver in the transmit band;
• and
• (d) if the determined transmit band leakage power is below a predetermined amount then using a lower power setting for the receiver whereas if the determined transmit band leakage power is above the predetermined amount then using a higher power setting for the receiver.

An apparatus comprising:

• a transmitter configured to output a signal in a transmit band;
• a receiver tuned to receive in the transmit band such that the receiver receives the signal output by the transmitter and generates a receive power reading indicative of a power of the signal as received by the receiver;
• and
• a processor configured to determine a transmit band leakage power at an input of the receiver in the transmit band based at least in part on the receive power reading, wherein if the determined transmit band leakage power is below a predetermined amount then the processor causes the receiver to be set to use a lower power setting whereas if the determined transmit band leakage power is above the predetermined amount then the processor causes the receiver to be set to use a higher power setting.

An apparatus comprising:

• a transmitter;
• a receiver;
• and
• means for determining a transmit band leakage power of a signal output by the transmitter in a transmit band and received on an input of the receiver, wherein the means is for determining the transmit band leakage power based at least in part on a receive power reading indicative of a power of the signal as received on the input of the receiver, wherein if the determined transmit band leakage power is below a predetermined amount then the means causes the receiver to be set to use a lower power setting whereas if the determined transmit band leakage power is above the predetermined amount then the means causes the receiver to be set to use a higher power setting.

A processor-readable medium storing a set of processor-executable instructions, wherein execution of the set of processor-executable instructions by a processor is for:

• causing a transmitter to be tuned to output a signal in a transmit band;
• causing a receiver to be tuned to the transmit band such that the receiver receives the signal output by the transmitter and generates a receive power reading indicative of a power of the signal as received by the receiver;
• and
• determining a transmit band leakage power at an input of the receiver in the transmit band based at least in part on the receive power reading, wherein if the determined transmit band leakage power is below a predetermined amount then the receiver is set to use a lower power setting whereas if the determined transmit band leakage power is above the predetermined amount then the receiver is set to use a higher power setting.
