Abstract:
The present disclosure relates to a pre-5 th -Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4 th -Generation (4G) communication system such as Long Term Evolution (LTE). The present disclosure discloses a method for effective retransmission when HARQ is applied to data encoded with a low density parity check (LDCP) code. A data transmission method of the transmitter may include: initially transmitting data encoded with an LDPC code to a receiver; receiving a negative acknowledgement (NACK) from the receiver; determining retransmission related information for data retransmission; and retransmitting, in response to the NACK, LDPC-encoded data based on the retransmission related information.

Claim (Index 13):
A receiver capable of information reception, the receiver comprising:\n a controller configured to control to:\n identify a bit sequence based on a signal received from a transmitter, \n generate log likelihood ratio (LLR) values based on the identified bit sequence, and \n output information bits by performing low density parity check (LDPC) decoding on the generated LLR values based on a parity check matrix selected from among a plurality of parity check matrices, \n wherein a start point of the bit sequence is determined based on a redundancy version index and the selected parity check matrix.
