    Abstract: The disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The disclosure relates to encoding and decoding by using a polar code in a wireless communication system, and an operation method of a transmission-end apparatus includes determining segmentation and the number of segments, based on parameters associated with encoding of information bits, encoding the information bits according to the number of check bits, and transmitting the encoded information bits to a reception-end apparatus.

    Abstract: This disclosure relates to a 5G or pre-5G communication system for supporting a higher data transfer rate than a 4G communication system such as LTE. The present invention relates to a method for encoding and decoding a channel in a communication or broadcasting system, comprising the steps of: determining an input bit size (CBS); determining a code rate (R); determining a size (Z) of a block; comparing the determined CBS and code rate with predetermined reference values; determining an LDPC sequence to perform LDPC encoding according to the comparison result; and performing LDPC encoding and decoding on the basis of the LDPC sequence and the block size. Further, the present invention comprises the steps of: determining a code rate (R) indicated by a modulation and coding scheme (MCS) index; determining a transport block size; and determining either a first basic matrix or a second basic matrix as a basic matrix on the basis of the transport block size and the code rate.

    Abstract: The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data transmission rate than a 4th generation (4G) communication system such as long-term evolution (LTE). Disclosed is a method performed by a terminal that may comprise: receiving configuration information for a CSI report from a base station; acquiring a channel quality indicator (CQI) table on the basis of the configuration information for the CSI report; and transmitting CSI including a CQI according to the CQI table to the base station, wherein the CQI table is configured on the basis of a first CQI table of a case where transport block error probability is 0.1 and a second CQI table for a case where transport block error probability is 0.00001. The method performed by the terminal may further comprise: receiving configuration information relating to a physical uplink shared channel (PUSCH) or a physical downlink shared channel (PDSCH) from the base station; identifying a modulation and coding scheme (MCS) table on the basis of the configuration information relating to the PUSCH or PDSCH; and acquiring a transport block size (TBS) on the basis of the MCS table, wherein the MCS table is configured on the basis of a first MCS table configured by default and a second MCS table configured for low spectral efficiency (SE) in the base station.
