Adaptive cellular power control

A mobile wireless communication device, comprising:

• a first transceiver that receives signals through a wireless non-cellular connection;
• a second transceiver that transmits signals through a wireless cellular connection;
• and
• a control processor coupled to the first and second transceivers, wherein the control processor mitigates interference in the mobile wireless communication device by:
• estimating a performance impact to signals received by the first transceiver from signals transmitted by the second transceiver;
• adjusting an actual transmit power of the second transceiver based on the performance impact estimation;
• and
• repeating periodically the estimating and adjusting while both the wireless non-cellular and wireless cellular connections are active;
• wherein the actual transmit power of the second transceiver is less than a requested transmit power for an uplink of the wireless cellular connection.

Computer readable medium for storing computer program code executable by a processor for mitigating interference in a mobile wireless communication device comprising:

• non-transitory computer program code for estimating a performance impact to signals received by a first transceiver of the mobile wireless communication device through a wireless non-cellular connection from signals transmitted by a second transceiver of the mobile wireless communication device through a wireless cellular connection;
• non-transitory computer program code for adjusting an actual transmit power of the second transceiver based on the performance impact estimation;
• and
• non-transitory computer program code for periodically repeating the estimating and adjusting while the wireless non-cellular and wireless cellular connections are active;
• wherein the actual transmit power of the second transceiver is less than a requested transmit power for an uplink of the wireless cellular connection.

An apparatus for adjusting transmit signals output by a cellular transceiver in a mobile wireless communication device, the apparatus comprising:

• means for estimating a performance impact to signals received by a non-cellular transceiver of the mobile wireless communication device from signals transmitted by the cellular transceiver;
• means for determining a requested transmit power level for the transmit signals output by the cellular transceiver, the requested transmit power level at least partially based on messages received from a network subsystem to which the cellular transceiver connects;
• means for adjusting an actual transmit power level of the transmit signals to a value different than the requested transmit power level when the performance impact to signals received by the non-cellular transceiver exceeds a threshold;
• and
• means for repeating the estimating, determining and adjusting periodically while the cellular and non-cellular transceivers are active.
