Base station apparatus, terminal apparatus, communication method, and integrated circuit
A terminal apparatus includes a receiver and a transmitter. The receiver is configured to receive a radio resource control (RRC) parameter and a physical downlink control channel (PDCCH) including a downlink control information (DCI) format and scheduling a physical uplink shared channel (PUSCH). The transmitter is configured to transmit the PUSCH with frequency hopping within one slot. The RRC parameter indicates one or a plurality of frequency offset values. The PUSCH includes a first frequency hop and a second frequency hop within the one slot. In a case that a cyclic redundancy check (CRC) scrambled with or other than a temporary cell-radio network temporary identifier (TC-RNTI) is added to the DCI format, a frequency offset between the first frequency hop and the second frequency hop is based on a size of an initial uplink (UL) bandwidth part (BWP) or the RRC parameter, respectively.
