摘要： A terminal apparatus of the present invention receives setting of an initial DL BWP by using an RRC message, the setting of the initial DL BWP comprises setting a first parameter and a second parameter of a CORESET #0, a value of an identifier of the CORESET #0 is 0, the first parameter represents the size of the CORESET #0, and the second parameter represents the size of the initial DL BWP. The terminal apparatus of the present invention receives a DCI format that schedules a PDSCH in an active DL BWP, and identifies, based on a field in the DCI format, a resource block set to which the PDSCH is allocated. A value of the field is determined based on the size of the DL BWP, the start resource block, and the number of consecutively allocated resource blocks. The size of the DCI format in a USS is determined based on the size of the CORESET #0, and when the field is applied to the active DL BWP, the size of the DL BWP is the size of the CORESET #0.

摘要： A terminal apparatus and a base station apparatus efficiently communicate. A terminal apparatus including a receiver configured to receive an RRC message including first configuration information and to receive DCI on a PDCCH, a determination unit configured to determine a time parameter for transmitting a PUSCH, based on a bit sequence indicated by a first field of the DCI, and a transmitter configured to transmit the PUSCH, based on the time parameter. A relationship between the bit sequence and the time parameter is defined by a first parameter group in a case that a first condition is satisfied and that the first configuration information includes the first parameter group and the relationship between the bit sequence and defined by a second parameter group in a case that a second condition is satisfied and that the first configuration information includes the second parameter group.

摘要： 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.
