Title:
CARRIER AGGREGATION CONTROL METHOD, RADIO FREQUENCY FRONT-END DEVICE, CIRCUIT, TERMINAL AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/088854
Kind Code:
A1
Abstract:
Disclosed are a carrier aggregation control method, a radio frequency front-end device, a radio frequency circuit, a terminal device and a readable storage medium. The carrier aggregation control method comprises acquiring a CA combination type to be generated, and a corresponding first uplink signal and second uplink signal; processing the first uplink signal by means of a multiplexer combination and a radio frequency switch, so as to obtain a first carrier aggregation signal; processing the second uplink signal by means of multiplexing a common carrier processing module, so as to obtain a second carrier aggregation signal; and finally, combining the first carrier aggregation signal and the second carrier aggregation signal by means of a diplexer, so as to obtain a CA combined uplink signal. According to the present application, multiple CA combinations can be simultaneously realized, and costs are saved on, thereby taking both the performance and costs into consideration.
