Mobile terminal devices and methods for apportioning uplink transmission power in mobile communication devices

Abstract:

A method for apportioning uplink transmission power in a mobile communication device is disclosed including determining a maximum power limit for the mobile communication device, identifying a first wireless transmission scheduled to transmit at a first power and a first time according to a first radio access technology (RATI); identifying a second wireless transmission scheduled to transmit at a second power and a second time according to a second radio access technology (RAT2). An aggregate transmission power required for transmission is calculated and transmission is apportioned asymmetrically as to at least one of power and/or time between the first wireless transmission and the second wireless transmission where the required aggregate transmission power exceeds said maximum power limit. Transmitting at least one of said first and/or second wireless transmission according to said asymmetrical apportionment results in transmission within specified power limits.
