Methods, apparatus and machine-readable media relating to transmission and reconstruction of data streams using data duplication

A method performed by a first wireless transmitting node for transmitting a data stream to a wireless receiving node, the data stream comprising a sequence of data items, the method comprising:

• causing transmission of a plurality of data packets to the wireless receiving node, by one or more wireless transmitting nodes, comprising the first wireless transmitting node, each data packet comprising respective duplicate copies of data items belonging to the data stream;
• and
• causing transmission to the wireless receiving node of an indication of an algorithm to be used by the wireless receiving node 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, 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.
