Abstract: A method and an apparatus for transmitting data in a wireless communication system are provided. A length of a circular buffer associated with rate matching is identified. Rate matching is performed for a code block based on the circular buffer. The data is transmitted based on the rate matching. In case that the rate matching is limited buffer rate matching (LBRM), the length of the circular buffer associated with the LBRM is determined based on a value obtained by dividing a reference transport block size (TBS) by a product of a number of code blocks and a reference code rate for the LBRM.
