1. A method performed by a wireless receiving node for receiving a data stream from one or more wireless transmitting nodes, the data stream comprising a sequence of data items, the method comprising:
receiving an indication of an algorithm from a wireless transmitting node of the one or more wireless transmitting nodes, wherein the algorithm is one of a plurality of candidate algorithms, wherein the indication comprises an index settable to a plurality of values associated with the plurality of candidate algorithms, and wherein the index is set to a value associated with the algorithm;
receiving a plurality of data packets from the one or more wireless transmitting nodes, each data packet comprising respective duplicate copies of data items belonging to the data stream; and
utilizing the algorithm to select, based on respective times at which the data packets are received, for each position in the sequence, one or more of the duplicate copies of data items for reconstruction of the data stream.
