5. A system comprising a terminal and a base station, wherein the terminal comprises:
a receiver that receives a downlink control information (DCI) format 0_0 for scheduling a physical uplink shared channel (PUSCH); and
a processor that, when one or more physical uplink control channel (PUCCH) resources are configured on an active uplink bandwidth part (BWP) of a cell for the PUSCH and all of the one or more PUCCH resources do not include spatial relation information, determines, based on quasi co-location (QCL) assumption of a certain control resource set, a spatial relation for the PUSCH,
wherein, when the one or more PUCCH resources are configured on the active uplink BWP and all of the one or more PUCCH resources do not include spatial relation information, the processor estimates, based on the QCL assumption, pathloss for the PUSCH and controls, based on the pathloss for the PUSCH and transmission power control (TPC) command value included in the DCI format 0_0, transmission power of the PUSCH, and the base station comprises:
a transmitter that transmits the PUSCH to the terminal.
