    Abstract: A method of a user equipment (UE) in a wireless communication system is provide. The method includes: receiving, from a base station, physical downlink shared channel (PDSCH) configuration information including a higher layer parameter for a modulation and coding scheme (MCS) table; identifying the MCS table for a PDSCH based on the higher layer parameter for the MCS table; receiving, from the base station, the PDSCH; and decoding, based on the identified MCS table, the PDSCH, wherein, in case that the higher layer parameter for the MCS table indicates a 1024-quadrature amplitude modulation (QAM), the MCS table for the PDSCH is identified as an MCS table with a maximum modulation order of 10, and wherein the MCS table with the maximum modulation order of 10 includes a set of combinations comprising a modulation order and a target code rate, the set of combinations including: (10, 805.5/1024), (10, 853/1024), (10, 900.5/1024), and (10, 948/1024).

    Abstract: Disclosed are a communication scheme and a system thereof for converging IoT technology and a 5G communication system for supporting a high data transmission rate beyond that of a 4G system. The disclosure can be applied to intelligent services (for example, services related to a smart home, smart building, smart city, smart car, connected car, health care, digital education, retail business, security, and safety) based on the 5G communication technology and the IoT-related technology. A decoding method includes: performing decoding through an inner code; detecting an error through an outer code; determining a re-encoding method; and performing re-encoding. A method for processing a signal includes decoding a first layer signal to determine first LDPC information bits, encoding the first LDPC information bits and a first parity bits to determine second parity bits; identifying a part of the first LDPC information bits, and decoding a second layer signal.

    Abstract: Disclosed are: a communication method for merging, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system; and a system thereof. The present disclosure can be applied to intelligent services (for example, smart home, smart building, smart city, smart car or connected car, healthcare, digital education, retail, security and safety related services, and the like) on the basis of a 5G communication technology and an IoT-related technology. A method by which a transmitter in a communication system transmits signals, according to one embodiment of the present specification, comprises the steps of: determining depth information for generating a mother code size and a parity bit; applying a polar code sequence corresponding to an information bit; generating, on the basis of the mother code size and the depth information, a codeword including a parity bit associated with at least two bits among a plurality of bits to which the polar code sequence is applied; and transmitting the generated codeword.
