BASE STATION DEVICE AND TERMINAL DEVICE

WIPO Patent Application WO/2019/150889

A1

This terminal device communicates with a base station device, and comprises a reception unit that receives control information, and a transmission unit that transmits data in accordance with the control information. The reception unit receives at least RRC and DCI. Included in the RRC are settings for a target received power, fractional TPC and closed loop TPC indexes, which are used for transmission of a PUSCH, and information designating, as parameters for transmission power control to be switched by the DCI, at least the target received power, fractional TPC and closed loop TPC indexes. When the DCI designating switching of a transmission power value is detected, the transmission power used for data transmission is differentiated from a transmission power value calculated by parameters reported as the parameters for the transmission power control to be switched.
