1. A terminal comprising:
a transmitter that reports capability information supporting a transmission configuration indication (TCI) state of uplink (UL);
a receiver that receives downlink control information (DCI) indicating a UL TCI state identifier, and receives, by higher layer signaling, a mapping between the UL TCI state identifier and a parameter related to uplink (UL) shared channel (PUSCH) transmission power control; and
a processor that determines, based on the UL TCI state identifier and the mapping, a parameter used for the PUSCH transmission power control after the transmitter reports the capability information,
wherein the processor determines, based on a configuration of power control of a PUSCH by a Sounding reference signal Resource Indicator (SRI), a parameter used for the PUSCH transmission power control in response to the transmitter not reporting the capability information, and
wherein the configuration includes an identifier of a PUSCH path loss reference Reference Signal (RS) and a closed loop index.
