Abstract
A remote radio head system (RRH) transmits first Radio-Frequency-signals (signals) at a first frequency-band (band) and second signals at a second band. The RRH receives and processes first control-data (data) to determine a first duty-cycle (cycle). In response to the first data and based on the first cycle, the RRH switches power between a first power amplifier system (PA) and a second PA and transmits the first signals at the first band through the first PA and transmits the second signals at the second band through the second PA. The RRH receives and processes second data to determine a second cycle. Responding to the second data and based on the second cycle, the RRH switches power between the first PA and the second PA and transmits the first signals at the first band through the first PA and transmits the second signals at the second band through the second PA.
