摘要： A channel encoding method in a communication or broadcasting system is provided. The channel encoding method includes reading a first sequence corresponding to a parity check matrix, converting the first sequence to a second sequence by applying a certain rule to a block size corresponding to a parity check matrix and the first sequence, and encoding information bits based on the second sequence. The block size has at least two different integer values.

摘要： Fifth Generation (5G) or pre-5G communication system for supporting a data transfer rate higher than that of a fourth Generation (4G) communication system, such as Long Term Evolution (LTE), and subsequent systems. The present disclosure provides a method for transmitting a signal by a transmission terminal in a communication system using a Low Density Parity Check (LDPC) code. The method include receiving a change request for changing a coding rate of the LDPC code, from a reception terminal; determining a first coding rate based on the change request; and transmitting information on the first coding rate in respond to the change request, to a reception terminal, wherein the change request for changing the coding rate comprises at least one of information indicating a coding rate determined by the reception terminal, or information indicating a state of the reception terminal.

摘要： The present disclosure relates to a 5th Generation (5G) or a pre-5G communication system provided to support a higher data transmission rate than a system beyond a 4th Generation (4G) communication system such as Long Term Evolution (LTE). The purpose of the present disclosure is to maximize adaptive transmission performance by designing a puncturing order and a repetition order individually in optimized order. An operation method of a transmission device for adaptive transmission of a codeword according to an embodiment of the present disclosure includes generating a codeword using a polar code and transmitting a packet including at least one codeword indicated by a repetition order when bit repetition is needed. The repetition order is determined based on at least one of channel polarization or channel quality information.

摘要： The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). An operation method of a receiving device in a wireless system includes receiving a polar codeword generated by a polar code, generating a majority of decoding paths by decoding a bit value corresponding to one index that is selected among a majority of indexes indicating respective bits included in the polar codeword, determining a first candidate group that includes at least one decoding path among the majority of decoding paths, and determining, as a second candidate group, at least one decoding path passing a CRC check among the first candidate group. A number of the at least one decoding path included in the first candidate group is determined based on a result of a CRC check performed prior to the CRC check.

摘要： Disclosed is a method for controlling interference for D2D communication. The method includes: identifying whether a position of a first user device belongs to a first area that satisfies a predetermined criterion; and if the position of the first user device is identified to belong to the first area, determining some resources constituting dedicated resources of the first area, among available resources of a signal for discovering a counterpart user device of D2D communication by the first user device, as resources of the signal.
