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.

A method of power detection in a carrier aggregation system, the method comprising:
- generating a time division duplexing carrier aggregated signal, the time division duplexing carrier aggregated signal including a time division duplexing aggregation of at least a first carrier associated with a first power amplifier and a second carrier associated with a second power amplifier;
- detecting, using a directional coupler in a signal path between a frequency multiplexing circuit and an antenna, an indication of power of the first carrier;
- and
- detecting, using the directional coupler, an indication of power of the second carrier.
A method of power detection in a carrier aggregation system, the method comprising:
- generating a frequency division duplexing carrier aggregated signal at a terminal of a frequency multiplexing circuit, the frequency division duplexing carrier aggregated signal including a frequency division duplexing aggregation of at least a first carrier associated with a first power amplifier and a second carrier associated with a second power amplifier;
- detecting, using a first directional coupler, an indication of power of the first carrier;
- and
- detecting, using a second directional coupler, an indication of power of the second carrier.
A carrier aggregation system comprising:
- a first power amplifier associated with a first carrier;
- a second power amplifier associated with a second carrier;
- a frequency multiplexing circuit configured to perform frequency domain multiplexing, the frequency multiplexing circuit including a terminal configured to provide a carrier aggregated signal, the carrier aggregated signal including an aggregation of at least the first carrier and the second carrier;
- and
- a directional coupler operatively coupled to the frequency multiplexing circuit, the directional coupler configured to provide an indication of power of an individual carrier of the carrier aggregated signal.
