Abstract: The present disclosure relates to a 5G communication system or a 6G communication system for supporting higher data rates beyond a 4G communication system such as long term evolution (LTE). A method performed by a receiving node in a wireless communication system is provided. The method comprises receiving, from a transmitting node, a codeword comprising at least one information bit, estimating a bit value of a first information bit of the at least one information bit as a first estimation bit value, and determining whether a log-likelihood ratio (LLR) indicating a probability ratio between bit values that are able to be estimated as the bit value of the first information bit is included in a first interval. In case that the LLR is included in the first interval, the method further comprises determining the bit value of the first information bit as a first estimation bit value or a second estimation bit value which is different from the first estimation bit value, by comparing a reliability value determined based on the LLR with at least one threshold.
