Base station apparatus, terminal apparatus, and communication method

A terminal apparatus that communicates with a base station apparatus, the terminal apparatus comprising:

• wireless reception circuitry configured and/or programmed to receive, from the base station apparatus, configuration information of a higher layer, and downlink control information and a UE-specific reference signal that have been multiplexed, and a downlink shared channel;
• and
• demultiplexing circuitry configured and/or programmed to demultiplex the downlink control information and the UE-specific reference signal that have been multiplexed, wherein
• in a case where the configuration information of a higher layer includes predetermined configuration information, receiving the downlink control information including information relating to a transmit power for the UE-specific reference signal,
• wherein the information relating to the transmit power for the UE-specific reference signal is an information indicating a power offset of a transmit power for a predetermined signal with respect to the transmit power for the UE-specific reference signal, and
• the transmit power for the predetermined signal is a sum of a transmit power for the downlink shared channel and a transmit power for an interference signal.
