Abstract: 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.

Abstract: Included are a receiver receiving a PDCCH and a PDSCH scheduled by the PDCCH, and a transmitter transmitting, on a PUCCH, one or multiple HARQ-ACKs including at least a HARQ-ACK corresponding to a TB included in the PDSCH and an SR.
For the HARQ-ACK of two or less bits, a resource of the PUCCH is, from one or multiple PUCCH resources in a PUCCH resource set, based at least on a first value based at least on the number of bits of the one or multiple HARQ-ACKs transmitted in the PUCCH, regardless of the number of resources of the SR overlapping with the PUCCH.
For the HARQ-ACK of more than two bits, the resource of the PUCCH is, from the one or multiple PUCCH resources in the PUCCH resource set, based at least on a sum of the number of bits of the one or multiple HARQ-ACKs and the SR.-
