The article presents the results error control technique whereby a forward error correction scheme is combined with request for retransmission of errorneous data (hybrid automatic repeat-request). The senders encodes the data using Code Division Multiple Access 2000 standard turbo-code with puncture technique prior to transmission. Encoded bits are saved according to a puncturing matrix and send to receiver. The additional information (redundancy) added by the code is used by the receiver to recover the original data. First burst includes only data symbols from systematic output of turbo-coder. Non-errors data reconstructed without retransmission and decoding, minor and major errors are corrected via a request for retransmission block of puncture turbo-code symbols.
