A terminal apparatus and a base station apparatus communicate efficiently. A terminal apparatus includes: a reception unit configured to receive an RRC message including first configuration information and receive downlink control information including a first field by a physical downlink control channel; and a transmission unit configured to perform one or more repetitive transmissions of a physical uplink shared channel based on the first configuration information and the first field. The first configuration information is information for configuring at least a starting symbol of a time resource corresponding to an index indicated by the first field, a number of symbols allocated to one PUSCH corresponding to the index indicated by the first field, and a nominal number of repetitive transmissions corresponding to the index indicated by the first field.
