Data mapping method and apparatus in wireless communication system

A method, performed by a user equipment (UE) of transmitting and receiving data in a wireless communication system, the method comprising:

• receiving code block group transmission information (CBGTI) for at least one code block (CB) included in a transport block (TB);
• determining a length of a sequence for the at least one CB based on the number of CBs of the TB or the number of scheduled CBs of the TB according to the CBGTI;
• and
• decoding the at least one CB based on the determined length of the sequence.

A base station for transmitting and receiving data in a wireless communication system, the base station comprising:

• a transceiver;
• at least one memory storing instructions;
• and
• at least one processor configured to execute the stored instructions to:
• determine whether a code block (CB), one of a plurality of CBs included in a transport block (TB), is scheduled for a transmission based on code block group transmission information (CBGTI),
• in response to the CB being scheduled for the transmission, determine a length of a sequence for the CB based on a number of CBs of the TB or a number of scheduled CBs of the TB,
• generate the sequence for the CB according to the determined length of the sequence, and
• control the transceiver to transmit a signal including the generated sequence.
