(57) Abstract :
A method for an electronic receiver of processing a packet of a hybrid automatic repeat request (HARQ) system is disclosed. The
method comprises receiving a first transmission of the packet, wherein the first transmission comprises a first plurality of soft
symbol values and determining whether the first plurality of soft symbol values meets a stop criterion. If it is determined that the
first plurality of soft symbol values does not meet the stop criterion, a subset of the first plurality of soft symbol values is
determined, wherein the subset comprises a number of soft symbol values of the first plurality of soft symbol values, the number
being greater than zero and less than the first plurality. The subset of the first plurality of soft symbol values is stored in a HARQ
buffer. A second plurality of soft symbol values, comprised in a second transmission of the packet received by the electronic
receiver, is combined with the stored subset of the first plurality of soft symbol values to produce a third plurality of combined
soft symbol values. Corresponding arrangement, receiver, device, and computer program product are also disclosed.
