A method for network coding at a packet data convergence protocol (PDCP) layer by a next-generation NodeB (gNB) includes selecting a coding coefficient from a location in a Vandermonde matrix. The method includes setting an identifier value identifying the location in the Vandermonde matrix corresponding to the selected coding coefficient. The method includes encoding one or more packets each comprising a PDCP data unit. The encoding of at least one of the one or more packets includes applying a function to data in the packet, the function including the coding coefficient. The method includes generating a message comprising the at least one encoded packet. The method includes transmitting the message to a user equipment (UE).
