An apparatus that is a terminal apparatus or a part thereof, the apparatus comprising: a measurement unit configured to measure multiple reference signal received powers, RSRPs, each of the multiple RSRPs corresponding to each of multiple second reference signals transmitted from a base station apparatus on a cell; a calculating unit configured to calculate a reference value of the RSRP of the cell by averaging N RSRPs of the multiple RSRPs or by averaging the N highest RSRPs of the multiple RSRPs; the apparatus characterized by comprising: a higher layer processing unit configured to receive, from the base station apparatus, an information through an upper layer signaling; a transmission power control unit configured to identify one or more first reference signals, the one or more first reference signals being identified by the information, wherein configurations for the first reference signals and configurations for the second reference signals are configurations of the same reference signal, and to determine a transmission power of a Physical Uplink Shared Channel, PUSCH, of the cell by using an RSRP corresponding to one of the one or more first reference signals. a measurement unit configured to measure multiple reference signal received powers, RSRPs, each of the multiple RSRPs corresponding to each of multiple second reference signals transmitted from a base station apparatus on a cell; a calculating unit configured to calculate a reference value of the RSRP of the cell by averaging N RSRPs of the multiple RSRPs or by averaging the N highest RSRPs of the multiple RSRPs; the apparatus characterized by comprising: a higher layer processing unit configured to receive, from the base station apparatus, an information through an upper layer signaling; a transmission power control unit configured to identify one or more first reference signals, the one or more first reference signals being identified by the information, wherein configurations for the first reference signals and configurations for the second reference signals are configurations of the same reference signal, and to determine a transmission power of a Physical Uplink Shared Channel, PUSCH, of the cell by using an RSRP corresponding to one of the one or more first reference signals. a higher layer processing unit configured to receive, from the base station apparatus, an information through an upper layer signaling; a transmission power control unit configured to identify one or more first reference signals, the one or more first reference signals being identified by the information, wherein configurations for the first reference signals and configurations for the second reference signals are configurations of the same reference signal, and to determine a transmission power of a Physical Uplink Shared Channel, PUSCH, of the cell by using an RSRP corresponding to one of the one or more first reference signals. to identify one or more first reference signals, the one or more first reference signals being identified by the information, wherein configurations for the first reference signals and configurations for the second reference signals are configurations of the same reference signal, and to determine a transmission power of a Physical Uplink Shared Channel, PUSCH, of the cell by using an RSRP corresponding to one of the one or more first reference signals.
