Abstract
A method of amplifying signals for transmission includes generating a signal in each of a plurality of subsystems. The subsystems each implement one of a plurality of radio access networks such that at least two different radio access networks are implemented. The method further includes amplifying signals generated by the subsystems with a power amplifier capable of amplifying input signals to a maximum power. The method also includes generating in each subsystem a power demand indicative of a power requested by that subsystem. Additionally, the method includes assigning a portion of the maximum power to each subsystem based upon the demands.
Claims20
A transmission apparatus comprising:
- a power amplifier, having an input and an output, the power amplifier operable to amplify signals input at the input and output the amplified signals at the output for onward transmission, the power amplifier being capable of amplifying input signals to a maximum power;
- a plurality of signal generating subsystems, each operable to provide, in use, a signal to be amplified to the input of the power amplifier;
- and
- a power control circuit, operable to assign a portion of the maximum power to each subsystem for amplification of each subsystem's signal;
- wherein each subsystem is operable to provide the power control circuit with a power demand indicative of the power required by that subsystem, wherein each power demand comprises at least two portions, each portion being indicative of power requested for transmitting a subset of the signals provided by that subsystem, and
- wherein the power control circuit is operable to vary the assignment of each subsystem's portion based upon the demands and to prioritize one of the portions from each of the subsystems over the others;
- and
- wherein the subsystems, in use, each implement one of a plurality of radio access networks such that at least two different radio access networks are implemented.
