The present invention related to a 5G or pre-5G communication system to be provided to support a higher data transmission rate since 4G communication systems like LTE. The present invention relates to a method and an apparatus for encoding a channel in a communication or broadcasting system supporting parity-check matrices having various sizes are provided. The method for a channel coding performed by an apparatus in a wireless communication system, the method comprising: identifying, using at least one processor of the apparatus, a number of input bits; identifying, using the at least one processor of the apparatus, a number of code blocks based on the number of the input bits and a maximum number of information bits corresponding to a largest parity-check matrix; identifying, using the at least one processor of the apparatus, a size of a code block based on the number of code blocks; identifying, using the at least one processor of the apparatus, the code block based on at least a part of the input bits and the size of the code block; identifying, using the at least one processor of the apparatus, a parity-check matrix based on the size of the code block; encoding, using an encoder of the apparatus, the code block based at least in part on the parity-check matrix; and transmitting, using a transceiver of the apparatus, at least a part of the encoded code block.
