Abstract (en)
[origin: WO2004015910A1] The invention relates to a method for data transmission in a communication system, whereby a transmission-end input data flow with serially successive data is transmitted via a time-variant transmission channel. According to said method, the transmission-end input data flow is divided into individual words. An a priori reliability value is determined for each position of a transmittal data block by means of transmission-end modulation methods and coding methods, and the words of the input data flow are associated with corresponding positions of the transmittal data block according to the a priori reliability values, and transmitted. An a posteriori reliability value is formed on the receiving end for each word of the transmittal data block. The words having an a posteriori reliability value falling below a pre-determined minimum value are re-requested and re-transmitted by acknowledgement of the corresponding positions.
