    Abstract: The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transmission rate beyond the 4G communication system such as LTE. A decoding method using a polar code according to an embodiment of the present disclosure comprises the steps of: determining a first function for decoding input bits and a second function, which is independent from a log likelihood ratio (LLR) value of a previous input bit by the first function; and decoding the input bits in parallel using the first function and the second function. Also, the method comprises the steps of: determining an internal frozen bit using at least one input frozen bit which has a predetermined value of a predetermined position from among the input bits; and determining LLR values for layer bits sequentially from the higher layers of N layers.

    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.
