1. A terminal apparatus comprising:
reception circuitry configured to receive a radio resource control (RRC) message including a first RRC parameter for notifying which one of a first repetition transmission type and a second repetition transmission type is to be configured; and
transmission circuitry configured to transmit, on a Physical Uplink Shared CHannel (PUSCH), a transport block scheduled by a downlink control information (DCI) format, wherein
the transmission circuitry performs, by applying the first repetition transmission type in a case that the first repetition transmission type is configured by the first RRC parameter, a repetition transmission of the transport block based on a first number of repetition transmissions,
the transmission circuitry performs, by applying the second repetition transmission type in a case that the second repetition transmission type is configured by the first RRC parameter and a second RRC parameter for indicating the first number of repetition transmissions and a second number of repetition transmissions is included in the RRC message, the repetition transmission of the transport block based on the second number of repetition transmissions,
for the first repetition transmission type, the repetition transmission of the transport block is performed only once within one slot,
for the second repetition transmission type, the repetition transmission of the transport block is performed one or more times within one slot,
the first number of repetition transmissions is indicated by the second RRC parameter in a case that the second RRC parameter is included in the RRC message,
the first number of repetition transmissions is indicated by a third RRC parameter for indicating the first number of repetition transmissions in a case that the second RRC parameter is not included in the RRC message and the third RRC parameter is included in the RRC message, and
the second number of repetition transmissions is indicated by the second RRC parameter included in the RRC message.
