Method and apparatus for performing interleaving in communication system

A method for interleaving an input bit sequence by an interleaver of a communication system including multiple interleavers, the method comprising:

• setting, by the interleaver of the communications system, a common parameter received from a base station, wherein the common parameter is to be used by the multiple interleavers and includes a transmission block length of each of the multiple interleavers and a prime seed value;
• setting, by the interleaver, a unique parameter for the interleaver received from the base station, wherein the unique parameter is set in view of a correlation between bit sequences that are input to the multiple interleavers;
• calculating an information value of the interleaver by using the common parameter and the unique parameter;
• calculating a temporal index by using the information value of the interleaver;
• comparing, by the interleaver, the transmission block length for the interleaver with the temporal index which is determined based on the common parameter and the unique parameter;
• generating, by the interleaver, an interleaving pattern based on a result of the comparison;
• and
• interleaving, by the interleaver, the input bit sequence according to the generated interleaving pattern by using a prime-power based on the common parameter and the unique parameter.
