    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 apparatus and a method for channel encoding and decoding in a communication or broadcasting system is provided. According to the present disclosure, the method for channel encoding in a communication or broadcasting system includes determining a block size Z, and performing encoding based on the block size and a parity check matrix corresponding to the block size, in which the block size is included in any one of the plurality of block size groups and the parity check matrix is different for each block size group.

    Abstract: A method and apparatus are provided for recovering data efficiently even when data loss has occurred over a channel or network. The packet transmission method includes arranging a first transmission packet in a source symbol in a first region of a source block; arranging a second transmission packet in a space starting with an empty space of a last source symbol where the first transmission packet is arranged, remaining after arranging the first transmission packet; arranging information related to the second transmission packet in a second region of the source block; performing Forward Error Correction (FEC) encoding on the source block; and transmitting the encoded source block.

    Abstract: A method for encoding and decoding information data using a polar code is provided. The method for encoding includes segmenting information data into a plurality of first packets, generating a plurality of second packets corresponding to the plurality of first packets by adding a corresponding packet Cyclic Redundancy Check (CRC) code to each of the plurality of first packets, fragmenting each of the plurality of second packets into a plurality of data blocks, polar code encoding each of the plurality of data blocks included in a corresponding second packet of the plurality of second packets, and generating a plurality of third packets corresponding to the plurality of second packets by concatenating each polar code encoded data block included in the corresponding second packet. The method for decoding includes decoding the third packet to obtain the information data based on the method for encoding.

    Abstract: A method and apparatus of transmitting/receiving a packet in a system are provided. The method includes dividing each symbol corresponding to each row of a two-dimensional array having a predetermined symbol size (T) as a width into a predetermined number (m) of regions, sequentially arranging source packets to be transmitted, starting from a first column of a first row of the two-dimensional array, setting a remaining part of a region in which last data of a source packet is allocated in a last row in which the source packet is arranged to a predetermined value, arranging a next source packet, starting from a starting point of a region next to the region in which the last data is allocated in the last row in which the source packet is arranged, constructing a source block by arranging all of the source packets in the two-dimensional array, FEC-encoding the source block, and transmitting the FEC-encoded source block.
