A mobile device configured to operate within a wireless communication network includes a Maximum Transmit Power Level (MTPL) controller. In order to meet specific absorption rate (SAR) limit requirements during simultaneous transmissions or during a dual connection mode, the mobile device employs a compact look-up table containing MTPL values and offset values. The MTPL controller generates runtime MTPL values for instances when the mobile device is operating in a stand-alone mode and for instances when the mobile device is operating in a simultaneous transmission mode. In the simultaneous transmission mode, the runtime MTPL value is generated by offsetting an MTPL value by an offset value.
