Abstract: The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data transfer rate beyond a 4th generation (4G) communication system, such as long term evolution (LTE). The present disclosure provides a method and an apparatus for efficiently performing encoding and decoding of an information bit in a wireless communication system. The present disclosure relates to an operation method of a transmitting terminal in a wireless communication system, the method comprising the steps of: generating padding bits on the basis of information bits; generating an input bit sequence including the padding bits and the information bits; generating a message by encoding the input bit sequence by using a polar code; and transmitting the message.

Abstract: A method for encoding streaming data according to one embodiment of the present invention comprises: a step of dividing a forward error correction (FEC) source block into one or more FEC sub-blocks; a first encoding step of FEC encoding said one or more FEC sub-blocks; a second encoding step of encoding said FEC source block; and a step of generating third encoded data including first encoded data encoded in the first encoding step and second encoded data encoded in the second encoding step. According to one embodiment of the present invention, a streaming service can be smoothly provided to multiple users in various environments or in a communication environment that varies according to movement or changes in a communication state. Further, a plurality of pieces of parity information can be transmitted to provide a streaming service which is capable of high reliability data recovery.
Abstract translation: 根据本发明的一个实施例的用于编码流数据的方法包括：将前向纠错（FEC）源块划分成一个或多个FEC子块的步骤; 对所述一个或多个FEC子块进行FEC编码的第一编码步骤; 编码所述FEC源块的第二编码步骤; 以及生成包括在第一编码步骤中编码的第一编码数据和在第二编码步骤中编码的第二编码数据的第三编码数据的步骤。 根据本发明的一个实施例，可以在各种环境中或在根据通信状态的移动或变化而变化的通信环境中向多个用户平滑地提供流服务。 此外，可以发送多条奇偶校验信息以提供能够进行高可靠性数据恢复的流服务。
