BAND28 FREQUENCY BAND BASED RADIO FREQUENCY APPARATUS AND COMMUNICATION METHOD THEREFOR

WIPO Patent Application WO/2017/024806

A1

Disclosed are a Band28 frequency band based radio frequency apparatus and a communication method therefor. The apparatus comprises: a first duplexer for signal transceiving of a first frequency band; a second duplexer for signal transceiving of a second frequency band; and a processor for choosing a duplexer to transceive a signal according to a frequency band to which a signal frequency belongs, wherein an overlapped frequency band belongs to a first frequency band and a test frequency point belongs to a second frequency band, the first and second frequency bands are combined to be a Band28 frequency band, and the second duplexer may suppress the overlapped frequency band, to satisfy the requirement of a full frequency band as Band28.
