Terminal apparatus, base station apparatus, and communication method

A base station apparatus comprising:

• a transmitter configured to transmit first RRC signaling;
• and
• a receiver configured to receive uplink control information transmitted on a PUCCH, wherein
• the first RRC signaling includes information indicating whether or not frequency hopping is applied to the PUCCH,
• transmit power of the PUCCH is given based on at least a parameter Δx, and
• the parameter Δx is given based on at least whether or not the frequency hopping is applied to the PUCCH.

A communication method used for a terminal apparatus, the communication method comprising the steps of:

• receiving first RRC signaling;
• determining transmit power of a PUCCH;
• and
• transmitting uplink control information on the PUCCH, wherein
• the first RRC signaling includes information indicating whether or not frequency hopping is applied to the PUCCH,
• the transmit power of the PUCCH is given based on at least a parameter Δx, and
• the parameter Δx is given based on at least whether or not the frequency hopping is applied to the PUCCH.
