Abstract
An apparatus and method for transmitting and receiving data in a wireless communication is provided. The method includes Low Density Parity Check (LDPC)-encoding LDPC information bits to generate a codeword, determining a number (Npunc) of bits to be punctured in parity bits of the codeword, determining a number (Npuncgroup) of parity bit groups in which all bits are punctured, and puncturing the all bits within 0th to (Npuncgroup−1)th parity bit groups indicated by a puncturing pattern, wherein the puncturing pattern is defined as an order of the parity bit groups defined as 29, 45, 43, 27, 32, 35, 40, 38, 0, 19, 8, 16, 41, 4, 26, 36, 30, 2, 13, 42, 46, 24, 37, 1, 33, 11, 44, 28, 20, 9, 34, 3, 17, 6, 21, 14, 23, 7, 22, 47, 5, 10, 12, 15, 18, 25, 31 and 39.
