4. A system comprising a terminal and a base station, wherein
the terminal comprises:
a receiver that receives a configuration of a physical uplink shared channel (PUSCH), receives a medium access control-control element (MAC CE), and receives downlink control information scheduling the PUSCH; and
a controller that controls transmission of the PUSCH, and
the base station transmits the configuration, transmits the MAC CE, and transmits the downlink control information,
when the configuration includes a list including values of a sounding reference signal resource indicator (SRI) field and IDs of reference signals for pathloss reference for the PUSCH, when the IDs correspond to the values respectively, when the MAC CE indicates a specific ID of a reference signal for pathloss reference corresponding to a specific value among the values, and when the downlink control information includes an SRI field indicating the specific value the specific value, the controller uses, for pathloss estimation of the PUSCH, the reference signal corresponding to the specific ID, and
when the reference signals are not configured, and when the MAC CE indicates a transmission configuration indication (TCI) state for a physical downlink control channel (PDCCH), the controller uses, for pathloss estimation of the PUSCH, a downlink reference signal in the TCI state with a quasi co-location type of a spatial reception parameter.
