Patent ID: 8588696

Claim:
A method of mitigating interference in an active mobile wireless communication device including a wireless cellular transceiver and a wireless non-cellular transceiver co-located in the mobile wireless communication device, the method comprising: estimating a receive signal quality for the wireless non-cellular transceiver that includes interference from signals transmitted by the wireless cellular transceiver; adjusting an actual transmit power of the wireless cellular transceiver based on the estimated receive signal quality, wherein adjusting the actual transmit power of the wireless cellular transceiver comprises: determining an unadjusted digital gain setting for a variable gain transmit amplifier in the wireless cellular transceiver based on one or more messages received through a downlink of the wireless cellular connection, determining a digital gain adjustment value based on the estimated receive signal quality, generating an adjusted digital gain setting for the variable gain transmit amplifier by combining the unadjusted digital gain setting and the digital gain adjustment value, and setting a gain of the variable gain transmit amplifier using the adjusted digital gain setting; and repeating periodically the estimating and adjusting; wherein the actual transmit power of the wireless cellular transceiver is less than a requested transmit power for the wireless cellular transceiver.
