Abstract
An ARQ data transmission scheme in which the overhead due to the ARQ control data is reduced to resolve the problem of the throughput deterioration. The error correction code for the original data is used for each re-transmission block or sub-block, and the block or sub-block corresponding to each re-transmission block or sub-block is found by carrying out the error correction operation with respect to each block or sub-block to be re-transmitted which is stored in the memory, so that there is no need to include the block or sub-block number for identifying each block or sub-block in the re-transmission frame, and consequently the ratio of the ARQ control data with respect to the transmission data can be made relatively smaller and the throughput can be improved.
