Patent ID: 8340161

Claim:
A method of transmitting data in a radio access system, the method comprising: generating one or more block sets using a plurality of blocks, wherein the plurality of blocks are divided from an input data; coding a first block set of the one or more block sets to produce a first coded block set; transmitting a predetermined number of coded blocks in the first coded block set to a receiver; receiving a signal indicating a state of a channel environment from the receiver; and packing an increased or decreased number of coded blocks, as compared to the predetermined number of coded blocks, according to the signal and transmitting the packed coded blocks to the receiver, wherein, if the signal indicates that the channel environment is better than a predetermined threshold, a second block set of the one or more block sets is coded to produce a second coded block set, a coded block is borrowed from the second coded block set, and the increased number of coded blocks are packed and transmitted to the receiver, and wherein random coefficients used for coding the first block set and the second block set are identical to each other.
