Abstract
(EN)
According to one aspect of the present invention for achieving the aforementioned or other purposes, a mobile terminal comprises: a first power amplifier for amplifying and outputting a first signal; a second power amplifier for amplifying and outputting a second signal; and a control unit for performing control such that each of the first power amplifier and the second power amplifier amplifies a signal of any one from among a plurality of communication systems, and thus a mobile terminal having an RF front-end common structure capable of supporting uplink MIMO in a plurality of wireless systems can be provided.
