## Abstract

An apparatus includes: a transmitter configured to transmit a transport block and HARQ-ACK on PUSCH; and a physical layer processing unit configured to calculate a number of coded bits for the HARQ-ACK, at least based on a number of SC-FDMA symbols NPUSCH-initialsymb for PUSCH initial transmission for the transport block, and modulation order for the transport block, wherein the number of the SC-FDMA symbols NPUSCH-initialsymb is given at least based on NLBT and a number of SC-FDMA symbols NULsymb included in an uplink slot, and a value of NLBT is 1 in a case that a time continuous signal of a first SC-FDMA symbol included in the PUSCH is generated based on a content of a resource element corresponding to a second SC-FDMA symbol following the first SC-FDMA symbol.
