Abstract
Aspects of this disclosure relate to detecting power associated with an individual carrier of a carrier aggregated signal. In an embodiment, an aggregated carrier including at least a first carrier and a second carrier is provided. An indication of power of the first carrier of the aggregated carrier is detected. Separately from detecting the indication of power of the first carrier, an indication of power of the second carrier of the aggregated carrier is detected. The power associated with a radio frequency (RF) signal provided to an RF source associated with the first carrier can be adjusted based on the indication of power of the first carrier.
Claims21
A method of detecting power associated with individual carriers of a carrier aggregated signal, the method comprising:
- providing an aggregated carrier including at least a first carrier and a second carrier;
- detecting an indication of power of the first carrier of the aggregated carrier;
- and
- separately from detecting the indication of power of the first carrier, detecting an indication of power of the second carrier of the aggregated carrier.
A method of controlling power associated with individual carriers of a carrier aggregated signal, the method comprising:
- detecting an indication of power of a first carrier of an aggregated carrier;
- adjusting a first power associated with a first power amplifier based at least partly on the indication of power of the first carrier, the first power amplifier being associated with the first carrier;
- separately from detecting the indication of power of the first carrier, detecting an indication of power of a second carrier of the aggregated carrier;
- and
- adjusting a second power associated with a second power amplifier based at least partly on the indication of power of the second carrier, the second radio power amplifier being associated with the second carrier.
A method of controlling power associated with an individual carrier of a carrier aggregated signal, the method comprising:
- detecting, using a directional coupler, an indication of power of a single carrier of an aggregated carrier, the aggregated carrier including at least the single carrier and a second carrier;
- and
- adjusting, using a feedback control circuit that is coupled between an output of the directional coupler and a power amplifier, a power associated with the power amplifier based at least partly on the indication of power of the single carrier.
