Terminal apparatus, base station apparatus, communication method, and integrated circuit

A terminal apparatus comprising:

• transmission circuitry configured to and/or programmed to transmit a transport block and HARQ-ACK on a PUSCH, and
• physical layer processing circuitry configured to and/or programmed to determine a number of coded bits for the HARQ-ACK at least based on a number of SC-FDMA symbols NPUSCH-initialsymb for an initial transmission of the PUSCH for the transport block, wherein
• the number of the SC-FDMA symbols NPUSCH-initialsymb is given based on NLBT and a number of SC-FDMA symbols included in a uplink slot NULsymb, and
• the NLBT is 1 in a case that a signal of a SC-FDMA symbol with index I is generated based on a content for resource elements corresponding to a SC-FDMA symbol with index I+1.

A base station apparatus comprising:

• reception circuitry configured to and/or programmed to receive a transport block and HARQ-ACK on a PUSCH, and
• physical layer processing circuitry configured to and/or programmed to determine a number of coded bits for the HARQ-ACK at least based on a number of SC-FDMA symbols NPUSCH-initialsymb for an initial transmission of the PUSCH for the transport block, wherein
• the number of the SC-FDMA symbols NPUSCH-initialsymb is given based on NLBT and a number of SC-FDMA symbols included in a uplink slot NULsymb, and
• the NLBT is 1 in a case that a signal of a SC-FDMA symbol with index I is generated based on a content for resource elements corresponding to a SC-FDMA symbol with index I+1.
