1. A terminal apparatus comprising:

  • a reference signal generating section configured to generate a first Sounding Reference Signal (SRS) with a first transmission time interval and a second SRS with a second transmission time interval, the second transmission time interval being different from the first transmission time interval, both of the first SRS and the second SRS being reference signals for channel-quality estimation;

    an offset setting section configured to set a first offset value to control transmission power used to transmit the first SRS and to set a second offset value to control transmission power used to transmit the second SRS, second offset value being different from the first offset value; and

    a transmitting section configured to transmit the first SRS with the transmission power controlled based on the first offset value and to transmit the second SRS with the transmission power controlled based on the second offset value.
