Apparatus and method for transmitting/receiving data in communication system

摘要

An apparatus and method for generating a parity bit sequence to be transmitted or received over a plurality of frames in a communication system are provided. The method includes puncturing a first parity bit sequence by encoding, the first parity bit sequence with a first puncturing pattern; outputting, as a basic parity bit sequence, non-punctured parity bits that are remaining after the puncturing of the first parity bit sequence with the first puncturing pattern; puncturing a second parity bit sequence that is punctured by puncturing of the first parity bit sequence with the first puncturing pattern, the second parity bit sequence with a second puncturing pattern; and outputting, as an additional parity bit sequence, non-punctured parity bits that are remaining after the puncturing of the second parity bit sequence with the second puncturing pattern.

1. A method for generating and transmitting a parity bit sequence by a transmission device in a communication system, comprising:
generating a basic masking pattern according to a basic puncturing pattern; masking a parity bit sequence with the basic masking pattern; outputting, as a basic parity bit sequence, non-punctured parity bits that are remaining after the masking of the parity bit sequence with the basic masking pattern; generating a first secondary masking pattern according to a secondary puncturing pattern; generating a first additional masking pattern based on the basic masking pattern and the first secondary masking pattern, masking the parity bit sequence with the first additional masking pattern; outputting, as a first additional parity bit sequence, non-punctured parity bits that are remaining after the masking of the parity bit sequence with the first additional masking pattern; and transmitting, from the transmission device to a receiving device of the communication system, the output basic parity bit sequence and the output first additional parity bit sequence, wherein the first additional parity bit sequence is transmitted in a frame preceding a particular frame in which the basic parity bit sequence is transmitted.
