摘要： A terminal apparatus and a base station apparatus can efficiently perform communication. In a radio communication system, an object is to efficiently provide, by a base station apparatus and a terminal apparatus, a terminal apparatus, a base station apparatus, a communication method, and an integrated circuit. Included in the terminal apparatus are a transmitter configured to transmit a sounding reference signal and a receiver configured to receive a higher layer configuration applied to transmit power control. A configuration is made from a higher layer to estimate downlink path loss used for the transmit power control applied to the transmission of the sounding reference signal by using a downlink reference signal of an activated BWP. In a case that a specific reference signal is not configured for the downlink reference signal, a reference signal of a synchronization signal block identified through a random access procedure is applied.
