  • HARQ procedure with processing of stored soft-bits
    Patent number: 8850283
    Abstract: It is described a method for determining a received data block by employing a Hybrid Automatic Repeat Request procedure. The described method comprises calculating (104) first soft-information values being associated with a first reception of the data block, storing the calculated first soft-information values in a first buffer (121), and calculating (104) second soft-information values being associated with a second reception of the data block, wherein the second reception results from a retransmission of the data block following the first reception. The described method further comprises rate matching (128) a first soft data block comprising the calculated and stored first soft-information values, rate matching (118) a second soft data block comprising the calculated second soft-information values, and decoding (152) a combination of the rate matched first soft data block and the rate matched second soft data block.
