COMMUNICATIONS APPARATUS AND METHOD FOR CONTROLLING RF SIGNAL PROCESSING COMPONENTS IN COMMUNICATIONS APPARATUS

The invention relates to a communications apparatus and a method for controlling RF signal processing components in the communications apparatus. The communications apparatus comprises a first radio module, a second radio module, and a radio frequency (RF) front-end circuit. The first radio module comprises at least a first baseband signal processing device and a first radio transceiver and provides at least a first wireless communications service in compliance with a first protocol. The second radio module comprises at least a second baseband signal processing device and a second radio transceiver and provides at least a second wireless communications service in compliance with a second protocol. The RF front-end circuit is coupled to the first radio module and the second radio module and comprises a plurality of RF signal processing components. A portion of the RF signal processing components capable of processing both a plurality of RF signals of the first radio module and a plurality of RF signals of the second radio module are coupled to both the first radio module and the second radio module for being shared by the first radio module and the second radio module. The first radio module and the second radio module are capable of establishing a dedicated wireless connection, simultaneously, via the RF front-end circuit.
