WIPO Patent Application WO/2014/175156

A1

Provided is a mobile communication terminal that can use both a state of simultaneously performing communications by use of two bands and a state of performing a communication by selection of one band to achieve appropriate adaptation. A mobile communication terminal of the present invention comprises: an antenna; a band-A transmission/reception circuit; a band-B transmission/reception circuit; a variable multiplexer; a recording unit that records a plurality of pieces of setting information for the variable multiplexer; and a filter control unit. The filter control unit controls the variable multiplexer in accordance with the setting information. The plurality of pieces of setting information include a piece of setting information corresponding to the state of simultaneously performing communications by use of both bands A and B, a piece of setting information corresponding to the state of performing a communication by use of only the band A and to a state of standby using the band A, and a piece of setting information corresponding to the state of performing a communication by use of only the band B and to a state of standby using the band B. The filter control unit sets the variable multiplexer on the basis of the setting information corresponding to any one of the states.
