Abstract
A terminal is disclosed including a transmission unit that transmits a Sounding Reference Signal (SRS) and a control unit that switches a carrier so as to transmit the SRS. The control unit determines a period during which no signal transmission is performed in radio frames used in a serving cell, based on a subcarrier spacing of a cell corresponding to a switching destination carrier.
