Abstract
(EN)
The present invention relates to a mobile terminal supporting a sounding reference signal (SRS). The present invention comprises: a plurality of antennas; a plurality of low noise amplifiers (LNAs) respectively formed between a combining unit for combining received signals and each antenna; a power amplifier (PA) for amplifying transmitted signals; a plurality of switches respectively formed between each of the plurality of LNAs and the combining unit and having paths formed between respective antennas and the PA by bypassing respective LNAs; a circulator connecting the PA to any one of the plurality of switches; and a switch control unit for controlling the plurality of switches such that each antenna is sequentially connected to the PA on the basis of the SRS transmission timing in which SRS information is transmitted.
