Patent ID: 8195250

Claim:
A method for controlling power among first and second wireless modems in a mobile communication device, comprising: commencing a communication activity at the first wireless modem; asserting a power control indicator while commencing the communication activity at the first wireless modem by setting a power cap flag used by a baseband processor of the second wireless modem; restricting a transmit power level of the second wireless modem to a reduced transmit power level while the power control indicator is asserted, the reduced transmit power level being lower than a maximum transmit power level of the second wireless modem and allowing the second wireless modem to perform communication activity; ceasing the communication activity at the first wireless modem; de-asserting the power control indicator in response to ceasing the communication activity at the first wireless modem; and commencing a communication activity at the second wireless modem, wherein the transmit power level of the second wireless modem is allowed to exceed the reduced transmit power level while the power control indicator is de-asserted; wherein the first and second wireless modems are commonly powered by a battery source.
