ENABLING RADIO FREQUENCY MULTIPLEXING IN A WIRELESS SYSTEM

摘要

A communication device comprises a set of filters that are selectively coupled to different groups of front end ports and an antenna port to form a diplexer, a single filter or a no filter connection for transmission and reception of different data signals. A processor operates to selectively determine or combine filters and couple them to the front end ports and the antenna port based on an operational mode and a frequency separation of signals operating in different frequency ranges of different operating bands. The operational mode can alter between a carrier aggregation mode, in which more than one operating band is aggregated during transmission or reception, and a non-carrier aggregation mode, in which only one filter, no filters or the diplexer is bypassed. The insertion loss of the transmissions and receptions can also be actively decreased.

主权项

1. A communication device comprising:
an antenna port configured to concurrently transmit or receive data streams operating in different frequency bands; and a plurality of filters configured to selectively couple to the antenna port and selectively form a diplexer to combine or separate the data streams operating in the different frequency ranges, based on an operation mode and a frequency separation between the different frequency ranges of the data streams.
