    Abstract: Techniques for closed loop power control in multi-transmission systems are discussed. One example system employing such techniques can include coupling circuitry configured to receive a transmission path signal comprising a plurality of signal components, wherein the plurality of signal components comprises at least a first signal component in a first frequency band and a second frequency component in a second frequency band distinct from the first frequency band; filter circuitry configured to receive the transmission path signal from the coupling circuitry, to separate the first signal component from the second signal component, and to separately output the first signal component and the second signal component; and power control circuitry configured to receive the first signal component and the second signal component, and to generate a first power control signal based on the first signal component and a second power control signal based on the second signal component.

    Abstract: An apparatus for determining information on a power variation of a transmit signal comprises a power amplifier module, an antenna module and a power variation determining module. The power amplifier module amplifies a radio frequency transmit signal and the antenna module transmits at least partly the amplified radio frequency transmit signal. The power variation determining module determines a weighted sum of a first feedback signal derived from the amplified radio frequency transmit signal and a second feedback signal derived from the amplified radio frequency transmit signal. The first feedback signal and the second feedback signal comprise different dependencies on a varying impedance at the antenna module. Further, the power variation determining module generates a power variation signal based on the weighted sum. The power variation signal comprises information related to a power variation of the amplified radio frequency transmit signal.

    Abstract: 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.
