Switching power between power amplifier systems in a remote radio head system

摘要

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.

1. A method of operating a remote radio head system to transmit first Radio Frequency (RF) signals at a first frequency band and to transmit second RF signals at a second frequency band, the method comprising:
receiving and processing first control data to determine a first duty cycle;in response to the first control data, switching power between a first power amplifier system and a second power amplifier system based on the first duty cycle, transmitting the first RF signals at the first frequency band through the first power amplifier system based on the first duty cycle, and transmitting the second RF signals at the second frequency band through the second power amplifier system based on the first duty cycle;
receiving and processing second control data to determine a second duty cycle;in response to the second control data, switching the power between the first power amplifier system and the second power amplifier system based on the second duty cycle, transmitting the first RF signals at the first frequency band through the first power amplifier system based on the second duty cycle, and transmitting the second RF signals at the second frequency band through the second power amplifier system based on the second duty cycle.
