Claim 17:
18. A device including a network node for network coding at a packet data convergence protocol (PDCP) layer, the device comprising:
at least one processing device;
a memory storing instructions for execution by the at least one processing device, the instructions when executed causing the at least one processing device to perform operations comprising:
selecting a coding coefficient from a location in a Vandermonde matrix, wherein the coding coefficient is based on a primitive element of the Vandermonde matrix, the primitive element being predefined for a user equipment (UE);
setting an identifier value identifying the location in the Vandermonde matrix corresponding to the selected coding coefficient;
encoding one or more packets each comprising a data unit, the encoding of at least one of the one or more packets comprising applying a function to data in each of the one or more packets, the function including the coding coefficient;
generating a message comprising at least one of the one or more encoded packets; and
causing transmission of the message to the UE independent of transmitting values of the coding coefficients to the UE.
