Method and apparatus for transmitting uplink control indicators in a wireless communication system

A base station apparatus comprising:

• reception circuitry configured to receive a transport block and hybrid automatic repeat request-Acknowledgement (HARQ-ACK) on a physical uplink shared channel (PUSCH), and
• physical layer processing circuitry configured to determine a number of coded bits for the HARQ-ACK at least based on a number of single-carrier frequency-division multiple access (SC-FDMA) symbols for an initial transmission of the PUSCH for the transport block (NPUSCH-initialsymb),
• wherein:
• NPUSCH-initialsymb is given based on an NLBT and a number of SC-FDMA symbols included in an uplink slot (NULsymb),
• the NLBT is 1 in a case that a signal of an SC-FDMA symbol with an index I comprises a portion of a content for resource elements corresponding to an SC-FDMA symbol with an index I+1,
• the SC-FDMA symbol with the index I is an earliest symbol in time among the NULsymb symbols in an uplink slot, and
• the SC-FDMA symbol with the index I+1 is a second earliest symbol in time among the NULsymb symbols in the uplink slot.
