摘要： A data receiver configured to receive a signal having at least two partial data packets, the data receiver being configured to estimate a state of a transmission channel, to obtain first channel state information, to demodulate a first set of received symbols from different data packets, to obtain a first set of received encoded bits, wherein the data receiver is configured to decode the first set of received encoded bits to determine, a first set of estimated encoded bits which corresponds more likely to a first set of transmitted encoded bits than the received encoded bits, and to map the first set of estimated bits to estimated transmission symbols using a mapping rule matching a transmitter-side mapping rule to obtain a first set of estimated transmission symbols, and to determine second channel state information using the first set of estimated transmission symbols.

摘要： Embodiments provide transfer methods. The method includes a step of transferring data of a first class from a data transmitter to a data receiver, wherein the data of the first class is transferred divided onto a first plurality of sub-data packets using a first hopping pattern. Furthermore, the method includes a step of transferring data of a second class from the data transmitter or a different data transmitter to the data receiver, wherein the data of the second class is transferred divided onto a second plurality of sub-data packets using a second hopping pattern, wherein transmission pauses between sub-data packets transferred according to the first hopping pattern are smaller than transmission pauses between sub-data packets transferred according to the second hopping pattern.

摘要： In embodiments, data transmitters and data receivers use, in a first mode, a first hopping pattern and a second hopping pattern for a repeated transfer of data, and, in a second mode, a third hopping pattern for the single transfer of data, wherein the hopping patterns of the first mode and the second mode are different so that a collision probability in the repeated transmission of data by a further data transmitter in a respectively different mode may be decreased and the transmission reliability may therefore be increased.
