Abstract
A power amplifier circuit including a plurality of analog power amplifiers configured to generate a output power for an output signal; at least one processor configured to: select a highest output power signal; determine an input signal power of a modulated signal; determine an output signal power based on the input signal power; compare the output signal power and the highest output power; and disable a subset of the plurality of analog power amplifiers based on the comparison, wherein a remainder of the plurality of analog power amplifiers are configured to generate the output signal power.
Claims17
A power amplifier circuit comprising:
- a plurality of analog power amplifiers configured to generate output signal power;
- and
- at least one processor configured to:
- select a highest output signal power;
- determine an input signal power of a modulated signal, wherein the input signal power is based on a plurality of input signal user data symbols, wherein the plurality of input signal user data symbols include one or more resource blocks, wherein the input signal power is based on a count of the resource blocks in the plurality of input signal user data symbols, wherein the modulated signal comprises the plurality of input signal user data symbols;
- determine an output signal power based on the input signal power;
- compare the output signal power and the highest output signal power;
- enable a power headroom;
- and
- disable a subset of the plurality of analog power amplifiers based on the comparison, wherein a remainder of the plurality of analog power amplifiers are configured to generate the output signal power, wherein the output signal power includes the power headroom.
A method for reducing static power consumption comprising:
- selecting a highest output signal power;
- determining an input signal power of a modulated signal based on a plurality of input signal user data symbols, wherein the plurality of input signal user data symbols include one or more resource blocks, wherein the input signal power is based on a count of the resource blocks in the plurality of input signal user data symbols, wherein the modulated signal comprises the plurality of input signal user data symbols;
- determining an output signal power based on the input signal power;
- comparing the output signal power and the highest output power;
- and
- disabling a subset of a plurality of analog power amplifiers based on the comparison, wherein a remainder of the plurality of analog power amplifiers are configured to generate the output signal power.
