Method and apparatus for determining downlink feedback information in wireless communication system

A method performed by a base station (BS) in a communication system, the method comprising:

• transmitting, to a terminal, first information configuring a code block group (CBG) based uplink (UL) transmission;
• receiving, from the terminal, UL data including one or more CBGs;
• and
• transmitting, to the terminal, second information indicating a positive-acknowledgement (ACK) or a negative-acknowledgement (NACK) according to a reception result for the UL data.

A terminal in a communication system, the terminal comprising:

• a transceiver;
• and
• a controller configured to:
• receive, from a base station (BS), first information configuring a code block group (CBG) based uplink (UL) transmission,
• transmit, to the BS, UL data including one or more CBGs, and
• receive, from the BS, second information indicating a positive-acknowledgement (ACK) or a negative-acknowledgement (NACK) according to a reception result of the BS for the UL data.
