Method and apparatus for data transmission in wireless cellular communication system

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

• a transceiver configured to transmit and receive a signal;
• and
• a controller configured to encode an information bit, generate an encoded bit, perform rate matching on the encoded bit, and transmit the rate-matched encoded bit to an base station,
• wherein the rate matching is performed in the case in which limited buffer rate matching (LBRM) is configured by a higher layer, based on a transport block size (TBS) when a preset condition is applied.

A method of transmitting a signal by an base station in a wireless communication system, the method comprising:

• encoding an information bit and generating an encoded bit;
• performing rate matching on the encoded bit;
• and
• transmitting the rate-matched encoded bit to a terminal,
• wherein the rate matching is performed in the case in which limited buffer rate matching (LBRM) is configured by a higher layer, based on a transport block size (TBS) when a preset condition is applied.
