主权项

1. A radio frequency transmit-receive apparatus, comprising:
a first antenna unit, configured to receive a first carrier aggregation signal, and to input the first carrier aggregation signal to a duplexer; the duplexer, configured to receive the first carrier aggregation signal from the first antenna unit, to divide the first carrier aggregation signal into first carrier signals, and to input each of the first carrier signals to a signal selecting unit corresponding to a frequency band; the signal selecting unit, configured to select a first channel to receive, in a time division duplex (TDD) timeslot, one of the first carrier signals from the duplexer, and to input the one of the first carrier signals to a radio frequency unit; and the radio frequency unit, configured to receive the first carrier signals from the signal selecting unit, and to demodulate each of the first carrier signals into respective first analog baseband signal; wherein the radio frequency unit is further configured to modulate second analog baseband signals into respective second carrier signals, and to send the second carrier signals to the signal selecting unit; wherein the signal selecting unit is further configured to select a second channel to receive, in the TDD timeslot, the second carrier signals from the radio frequency unit, and to send the second carrier signals to the duplexer; wherein the duplexer is further configured to receive the second carrier signals from the signal selecting unit, to combine the second carrier signals to obtain a second carrier aggregation signal, and to input the second carrier aggregation signal to the first antenna unit; and wherein the first antenna unit is further configured to receive the second carrier aggregation signal from the duplexer, and to transmit the second carrier aggregation signal.
