Method and apparatus for mapping uplink control information in wireless communication system

An operating method of a base station in a wireless communication system, the operating method comprising:

• transmitting downlink control information (DCI) for scheduling physical uplink shared control channel (PUSCH) transmission;
• and
• receiving, from the terminal, uplink control information (UCI) on a PUSCH based on a number of modulation symbols per layer for transmission of the UCI,
• wherein the number of modulation symbols per layer for transmission of the UCI is determined based on a number of code blocks associated with an uplink shared channel (UL-SCH), CUL-SCH, a value Kr for an r-th code block of the code blocks and a number of bits of the UCI, OACK,
• wherein in case that the DCI includes code block group transmission information (CBGTI) and the CBGTI indicates that the r-th code block associated with the UL-SCH of the PUSCH transmission is not for transmission, the value Kr for the UCI is determined as 0, and
• else, the value Kr for the UCI is determined as a size of the r-th code block for the UL-SCH of the PUSCH transmission.

A terminal in a wireless communication system, the terminal comprising:

• a transceiver;
• and
• a processor coupled with the transceiver and configured to:
• receive downlink control information (DCI) for scheduling physical uplink shared control channel (PUSCH) transmission,
• determine a number of modulation symbols per layer for transmission of uplink control information (UCI) based on a number of code blocks associated with an uplink shared channel (UL-SCH), CUL-SCH, a value Kr for an r-th code block of the code blocks and a number of bits of the UCI, OACK,
• wherein in case that the DCI includes code block group transmission information (CBGTI) and the CBGTI indicates that the r-th code block associated with the UL-SCH of the PUSCH transmission is not for transmission, the value Kr for the UCI is determined as 0, and
• else, the value Kr for the UCI is determined as a size of the r-th code block for the UL-SCH of the PUSCH transmission;
• and
• transmit, to a base station, the UCI on the PUSCH based on the number of modulation symbols per layer.
