Abstract
An electronic device disclosed herein includes mechanisms for modeling and dynamically controlling transmission power of an electronic device. The electronic device determines a back-off function defining at least one transmission power adjustment that is effective to adjust a predicted average energy emanating from an electronic device over the future time interval to satisfy a power condition. Power of the electronic device is adjusted according to the back-off function responsive to satisfaction of a proximity condition.
Claims20
A method comprising:
- determining a back-off function defining at least one transmission power adjustment, the at least one transmission power adjustment effective to adjust a predicted average energy of an electronic device over a future time interval to satisfy a power condition;
- and
- adjusting transmission power of the electronic device according to the back-off function responsive to satisfaction of a proximity condition.
An apparatus including:
- a back-off module that determines a back-off function defining at least one transmission power adjustment, the at least one transmission power adjustment effective to adjust a predicted average energy of an electronic device over a future time interval to satisfy a power condition;
- and
- a power controller that adjusts power of at least one transmitter of the electronic device according to the back-off function.
A method comprising:
- determining a back-off step function with a variable step size, the back-off step function defining at least one transmission power adjustment effective to adjust a predicted average energy of an electronic device over a future time interval to satisfy a power condition while maximizing total transmission power of the electronic device over the future time interval;
- and
- adjusting the transmission power according to the back-off step function responsive to detection of a proximity event.
