The RF front-end device is configured with an antenna terminal, a control terminal for receiving multiple control signals, and multiple input terminals for receiving multiple RF signals. The RF front-end device includes: a first switch unit having multiple first terminals connected to the multiple input terminals respectively; a power amplification unit, having an input terminal connected to a second terminal of the first switch unit, and an output terminal connected to the antenna terminal; and a control unit, where the control unit is connected to each of the control terminal and the power amplification unit, and is configured to control, based on a received target control signal, the power amplification unit to perform power amplification processing on a received target RF signal. The target control signal is one of the multiple control signals, and frequency bands of the multiple RF signals are different.

The present disclosure relates to a communication device and a communication control method. The communication device includes a radio frequency transceiver, multiple radio frequency modules, a radio frequency power supply, and an electric power supply. When the communication device is configured to support a standalone mode, the radio frequency power supply outputs a radio frequency voltage to individual radio frequency modules ready for transmission that are conductively connected to one transmission channel group, the radio frequency voltage being determined based on the power information of each radio frequency module. This can meet the higher power demand and greater radio frequency power consumption of each radio frequency module ready for transmission in the standalone mode. When the communication device is configured to support a combined mode of frequency bands of different transmission channel groups, the radio frequency power supply outputs the radio frequency voltage to a radio frequency module ready for transmission that are conductively connected to one transmission channel group, and the electric power supply outputs a power supply voltage to other radio frequency modules ready for transmission that are conductively connected to another transmission channel group. Different radio frequency modules simultaneously transmit radio frequency signals from different channel groups under the power supply of different power supplies, which can support the non-standalone mode and also the DSDA mode.
