Allocating transmit power among multiple air interfaces
First Claim
1. A method for allocating power among multiple air interfaces for a communication device supporting simultaneous transmission over multiple air interfaces, the method comprising:
- determining a first power level that is used for transmitting over a first air interface;
determining an available power level for transmitting over a second air interface;
comparing a difference between the available power level and the first power level to a power differential threshold;
setting a second power level for transmitting over the second air interface to the available power level in response to a determination that the difference between the available power level and the first power level fails to exceed the power differential threshold;
setting the second power level for transmitting over the second air interface to an adjusted power level in response to a determination that the difference between the available power level and the first power level exceeds the power differential threshold, wherein a difference between the adjusted power level and the first power level fails to exceed the power differential threshold; and
generating a power-based payload constraint based on at least the second power level.

Abstract
Systems and methods for allocating transmit power among multiple interfaces in a wireless communication system are disclosed. In one embodiment, the method comprises determining a first power level that is used for transmitting over a first air interface, determining a maximum power level available for transmitting over a second interface, comparing the first power level to the maximum power level, determining a second power level that is used for transmitting over the second air interface based on the comparison of the first power level to the maximum power level, and generating a power-based payload constraint based on the second power level.
