1. A user equipment (UE) comprising:
reception circuitry configured to receive, from a base station apparatus, a physical downlink control channel with a downlink control information (DCI) format;
transmission circuitry configured to perform physical uplink shared channel (PUSCH) repetition transmissions of a transport block (TB) scheduled by the DCI format; and
control circuitry configured to:
determine, based on a value of a time resource assignment field in the DCI format, a starting symbol of a first PUSCH in a first slot, and a first number of consecutive symbols counting from the starting symbol, and
determine, in a case that the first number of consecutive symbols counting from the starting symbol exceed a last symbol of the first slot, the first PUSCH within the first slot and a second PUSCH within a slot next to the first slot, wherein
a number of symbols of the first PUSCH is a second number of symbols from the starting symbol in the first slot to the last symbol of the first slot,
a number of symbols of the second PUSCH is a number of symbols given by subtracting the second number from the first number,
in a case that a number of first consecutively available symbols for PUSCH transmission within a transmission occasion of the first PUSCH exceeds a predetermined value, a repetition of the TB is performed in the first consecutively available symbols of the first PUSCH,
in a case that the number of the first consecutively available symbols for PUSCH transmission within the transmission occasion of the first PUSCH does not exceed the predetermined value, the repetition of the TB is not performed in the transmission occasion of the first PUSCH,
in a case that a number of second consecutively available symbols for PUSCH transmission within a transmission occasion of the second PUSCH exceeds the predetermined value, a repetition of the TB is performed in the second consecutively available symbols of the second PUSCH, and
in a case that the number of the second consecutively available symbols for PUSCH transmission within the transmission occasion of the second PUSCH does not exceed the predetermined value, the repetition of the TB is not performed in the transmission occasion of the second PUSCH.
