Managing electrical current in a portable computing device when two or more communications overlap in drawing power during a transmission

摘要

A method and system for managing electrical current within a portable computing device (“PCD”) includes assigning a priority to two or more communications supported by the PCD. A present level of a power supply for the PCD may be monitored by a communications power (“CP”) manager module. Next, the CP manager module may determine if the two or more communications may be transmitted at the present level of the power supply. If the two or more communications cannot be transmitted at the present level of the power supply, then the CP manager module may determine if a timing of at least one of the communications may be adjusted. The CP manager module may also determine a theoretical power level adjustment for at least one of the communications. The two or more communications may be transmitted with any calculated timing off sets and power level adjustments.

1. A method for managing electrical current within a portable computing device (“PCD”), the method comprising:
assigning a priority to two or more communications supported by the PCD which may overlap in drawing power during a transmission; monitoring a present level of a power supply for the PCD; determining if the two or more communications which may overlap in drawing power during the transmission may be transmitted at the present level of the power supply; if the two or more communications which may overlap in drawing power during the transmission cannot be transmitted at the present level of the power supply, then determining if a timing of at least one of the communications may be adjusted; if the timing of the at least one of the communications may be adjusted, then calculating a timing offset for the at least one of the communications; determining if the two or more communications may be transmitted at the present level of the power supply and with the timing offset so that power drawn for the communications is offset; and determining a theoretical power level adjustment for at least one of the communications if the two or more communications cannot be simultaneously transmitted at the present level of the power supply and with the timing offset.
