1. A terminal device comprising:
reception circuitry configured to receive a downlink control information (DCI) format for scheduling a physical uplink shared channel (PUSCH), which is mapped to X0 slots for a PUSCH repetition; and
transmission circuitry configured to transmit the PUSCH, wherein:
a size of a transport block transmitted in the PUSCH is determined by NRE=X1*min(156, NaRE)*nPRB,
the NaRE is determined by NRBsc*Nshsymb−NPRBDMRS−NPRBoh,
the nPRB is a number of physical resource blocks (PRBs) allocated for the PUSCH,
the NRBsc is a number of subcarriers per resource block (RB),
the Nshsymb is a number of orthogonal frequency division multiplex (OFDM) symbols allocated for the PUSCH in a duration,
the NPRBDMRS is a number of resource elements allocated for demodulation reference signals (DMRS) for the PUSCH in 1 PRB,
the NPRBoh is indicated by a first radio resource control (RRC) parameter,
the X1 is a first operator which controls the size of the transport block and is provided by a second RRC parameter,
the size of the transport block is determined by NRE=X1*min(156, NaRE)*nPRB in a case that a period for which one redundancy version (RV) is allocated spans more than one slot,
the X1 is different from the X0, and
the size of the transport block is determined by NRE=min(156, NaRE)*nPRB in a case that the period spans one slot.
