Abstract:
1. A method for communication, comprising: in a wireless communication terminal, modulating data to produce a composite, aggregated-spectrum signal comprising at least first and second signals in respective first and second spectral bands, amplifying the modulated data in at least two of the signals using a common Power Amplifier (PA) having a power constraint, and transmitting the modulated data in the first and second spectral bands from the wireless communication terminal to a base station at respective first and second power levels, wherein the first and second power levels are controlled individually; while communicating with the base station, receiving at the wireless communication terminal one or more instructions from the base station to set the first power level; setting the first power level so as to modify a ratio between the first power level and the second power level, wherein the first power level is set based on the instructions; and setting the power levels of the at least two of the signals so as to comply with the power constraint of the PA.
