A terminal apparatus comprising: a control section (204, 302) that controls transmission power of a sounding reference signal using an offset value corresponding to transmission power of a data signal; and a transmitting section that transmits the SRS with the transmission power, wherein: the control section (204, 302) controls the transmission power of the SRS using a first offset value when an SRS transmission subframe is a predetermined subframe, and the control section (204, 302) controls the transmission power of the SRS using a second offset value when the transmission subframe is a subframe other than the predetermined subframe; and the second offset value is an offset value set for transmission to a serving cell, and the first offset value is greater than the second offset value, characterized in that when coordinated transmission is performed by a plurality of base station apparatuses including a first base station apparatus, and a second base station apparatus that is located within a coverage area of the first base station apparatus, the predetermined subframe is a subframe in which a trigger of an aperiodic SRS is transmitted from the first base station apparatus or the second base station apparatus. a control section (204, 302) that controls transmission power of a sounding reference signal using an offset value corresponding to transmission power of a data signal; and a transmitting section that transmits the SRS with the transmission power, wherein: the control section (204, 302) controls the transmission power of the SRS using a first offset value when an SRS transmission subframe is a predetermined subframe, and the control section (204, 302) controls the transmission power of the SRS using a second offset value when the transmission subframe is a subframe other than the predetermined subframe; and the second offset value is an offset value set for transmission to a serving cell, and the first offset value is greater than the second offset value, characterized in that when coordinated transmission is performed by a plurality of base station apparatuses including a first base station apparatus, and a second base station apparatus that is located within a coverage area of the first base station apparatus, the predetermined subframe is a subframe in which a trigger of an aperiodic SRS is transmitted from the first base station apparatus or the second base station apparatus. the control section (204, 302) controls the transmission power of the SRS using a first offset value when an SRS transmission subframe is a predetermined subframe, and the control section (204, 302) controls the transmission power of the SRS using a second offset value when the transmission subframe is a subframe other than the predetermined subframe; and the second offset value is an offset value set for transmission to a serving cell, and the first offset value is greater than the second offset value, characterized in that when coordinated transmission is performed by a plurality of base station apparatuses including a first base station apparatus, and a second base station apparatus that is located within a coverage area of the first base station apparatus, the predetermined subframe is a subframe in which a trigger of an aperiodic SRS is transmitted from the first base station apparatus or the second base station apparatus.
