Abstract

A reduction in interference improves throughput and increase opportunity for communication by each terminal apparatus. A base station apparatus that communicates with a terminal apparatus transmits information relating to a transmit power for a UE-specific reference signal in a state of being included in downlink control information, in a case of a predetermined transmission mode. A terminal apparatus that communicates with a base station apparatus includes a reception unit that receives downlink control information which includes information relating to a transmit power for a UE-specific reference signal, from the base station apparatus, in a case of a predetermined transmission mode, and a reception signal is demodulated based on the downlink control information.
