摘要： The terminal apparatus receives one or more first blocks including a synchronization signal, receives first information and second information identifying one of the first blocks, and transmits a random access preamble in an available PRACH occasion identified based at least on the first information and the second information. At least one bit sequence of bit sequences indicatable by the second information indicates a PRACH occasion index indicating a physical random access channel occasion available for transmission of the random access preamble among PRACH occasions associated with the first block in an association period identified based on a physical random access channel configuration period indicated by higher layer signaling and the number of one or more first blocks.

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.
