Abstract: Disclosed is a method performed by a terminal in a wireless communication system, including performing rate matching for a code block based on a circular buffer, and transmitting, to a base station, uplink data based on the rate matching, wherein, in case that the rate matching is limited buffer rate matching (LBRM), a length of the circular buffer is determined based on a value obtained by dividing a transport block size (TBS) associated with the LBRM by a product of a number of code blocks of a transport block and a code rate associated with the LBRM.

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.
