1. A user equipment (UE), comprising: reception circuitry configured to receive, from a base station, system information including a first configuration of a first initial uplink (UL) bandwidth part (BWP) and a second configuration of a second initial UL BWP wherein the second configuration includes a first Radio Resource Control (RRC) parameter, the first RRC parameter configures a cell-specific physical uplink control channel (PUCCH) resource set on the second initial UL BWP, and the cell-specific PUCCH resource set includes one or more PUCCH resources, and to receive a physical downlink control channel (PDCCH) with a Downlink Control Information (DCI) format scheduling a physical downlink shared channel (PDSCH), and transmission circuitry configured to transmit, on a PUCCH resource of the one or more PUCCH resources, a PUCCH with HARQ-ACK information in response to the PDSCH in the second initial UL BWP, wherein whether the UE uses a first formula or a second formula to calculate a physical resource block (PRB) index of the PUCCH resource is determined based on one, more or all of a first frequency domain location of the first initial UL BWP, a first bandwidth of the first initial UL BWP, a second frequency domain location of the second initial UL BWP, and a second bandwidth of the second initial UL BWP, wherein the first formula uses a size of the second initial UL BWP as one of terms of the first formula, and the second formula does not use the size of the second initial UL BWP as one of terms of the second formula.
