Patent ID: 8711978

Claim:
A communication method using soft decision in a wireless access system, the method comprising: receiving, by a receiver, first code blocks from a transmitter; arranging the received first code blocks in descending order of their soft decision levels; transmitting a retransmission request message requesting a retransmission of at least one of the first code blocks having a soft decision level lower than a predetermined soft decision level; receiving at least one of second code blocks retransmitted in response to the retransmission request message; rearranging the first code blocks and the retransmitted second code blocks in descending order of their soft decision levels; and performing a first random linear decoding on a first code block set, wherein the first code block set is constructed of the rearranged first code blocks and the rearranged second code blocks arranged in descending order of their soft decision levels, wherein the first code blocks and the second code blocks are random-linear-coded.
