System and method for dropping and adding an air interface in a wireless communication system

A device for dropping an air interface, the system comprising:

• a transceiver configured to concurrently communicate over a first air interface and a second air interface;
• and
• a processor configured to determine:
• whether a violation of a power constraint indicative of a power imbalance has occurred by:
• measuring a receive power of the first air interface and a receive power of the second air interface;
• determining a difference between the measured receive power of the first air interface and the measured receive power of the second air interface, and
• determining whether a value of the determined difference is greater than a predefined threshold, indicating the power imbalance;
• and
• whether the second air interface is in an idle state if the power constraint is violated;
• wherein the processor is configured to provide an instruction to the transceiver to drop the second air interface if it is determined that the power constraint is violated and the second air interface is in the idle state.

A device for dropping an air interface, the device comprising:

• means for concurrently communicating over a first air interface and a second air interface;
• means for determining whether a violation of a power constraint indicative of a power imbalance has occurred by:
• measuring a receive power of the first air interface and a receive power of the second air interface;
• determining a difference between the two measurements, and
• determining whether a value of the difference is greater than a predefined threshold, indicating the power imbalance;
• means for determining whether the second air interface is in an idle state if the power constraint is violated;
• and
• means for dropping the second air interface, if it is determined that the power constraint is violated, and if it is determined that the second air interface is in the idle state.
