Method and apparatus for transmitting control and data information in wireless cellular communication system

A method performed by a base station in a wireless communication system, the method comprising:

• transmitting, to a terminal, downlink control information (DCI) associated with a transport block, wherein at least one code block is included in the transport block, and a new data indicator, one bit information for combining, and hybrid automatic repeat request (HARQ) process number information are included in the DCI;
• and
• transmitting, to the terminal, the at least one code block based on the new data indicator, the one bit information for combining, and the HARQ process number information included in the DCI,
• wherein in case that the new data indicator is associated with retransmission and a value of the one bit information for combining is 1, the transmitted at least one code block is combinable with an earlier transmitted at least one code block, and
• wherein in case that the new data indicator is associated with retransmission and the value of the one bit information for combining is 0, the transmitted at least one code block is not combinable with the earlier transmitted at least one code block.

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

• a transceiver configured to transmit and receive a signal;
• and
• a controller configured to:
• receive, from a base station, downlink control information (DCI) associated with a transport block, wherein at least one code block is included in the transport block, and a new data indicator, one bit information for combining, and hybrid automatic repeat request (HARQ) process number information are included in the DCI, and
• receive, from the base station, the at least one code block based on the new data indicator, the one bit information for combining, and the HARQ process number information included in the DCI,
• wherein in case that the new data indicator is associated with retransmission and a value of the one bit information for combining is 1, the received at least one code block is combinable with an earlier received at least one code block, and
• wherein in case that the new data indicator is associated with retransmission and the value of the one bit information for combining is 0, the received at least one code block is not combinable with the earlier received at least one code block.
