ABSTRACT:
An apparatus and method are provided for transmitting a signal in a communication system using a low density parity check (LDPC) code. An LDPC codeword is generated by encoding an information word at a coding rate. A puncturing pattern is generated when a hybrid automatic repeat request (HARQ) scheme to be applied to the LDPC codeword is an incremental redundancy (IR) scheme. An additional pattern is generated when the HARQ scheme to be applied to the LDPC codeword is a partial chase combining (CC) scheme. A signal is transmitted by applying the puncturing pattern to the LDPC codeword at an associated coding rate when the HARQ scheme to be used is the IR scheme. A signal is transmitted by applying the additional pattern to the LDPC codeword at an associated coding rate when the HARQ scheme to be used is the partial CC scheme.
