Abstract: 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). According to an embodiment of the disclosure, in a wireless communication system, a remote terminal transmits a relay request message to a target relay terminal. The remote terminal performs an IP allocation procedure with the target relay terminal. The remote terminal performs relay communication with the target relay terminal on the basis of the IP allocation procedure. The IP allocation procedure is performed using an IP address which has been used in previous relay communication with a source relay terminal.

Abstract: 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.

Abstract: 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.
