Patent ID: 7620871

Claim:
A method for determining an error rate in a data transmission from a transmitter/receiver station to a transmitter/receiver device, wherein a first data block and at least one further, redundant data block different from the first data block are generated by the transmitter/receiver station from an original data block and, in the event of an error transmission of the first data block, a further, redundant data block is requested by the transmitter/receiver device, comprising the steps of: transmitting a first data block by the transmitter/receiver station, receiving the first data block by the transmitter/receiver device, decoding the first data block received in a decoding block, checking the first data block for transmission errors, requesting a further, redundant data block for error correction, if an error is determined in the transmitted data of the first data block, receiving the request in the transmitter/receiver station, retransmitting the first data block, and determining the rate of the incorrectly received first data blocks, without error correction, and wherein a further, redundant data block is additionally transmitted by the transmitter/receiver station in the event of a request for a further data block, in order to compare the determined error rate without error correction with an error rate with error correction by incremental redundancy.
