PURPOSE: An error restoring method is provided to shorten the time for retransmitting an error information block (e.g. deteriorated frame) and to improve the throughput of a communication channel where information is transported by applying a data puncture operation to information transmitted by a communication system, based on information on a received signal. CONSTITUTION: A receiver of a user device receives an information block via a forward link. Feedback or error restoration data extracted by a processor is contained in the received information block and it is decided whether previous information transmitted by the user device is to be retransmitted. The user device transmits appropriate decoding status data to information which is transmitted at present and time, when the information block is retransmitted is reduced. The insertion of decoding status data into transmitted information is called data puncture.
