Abstract: 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).

Abstract: Systems and methods of providing policy and charging control in an information-centric network are described. An interest packet is transmitted from a content consumer to a holder through a gNB, ICN-PoA and ICN-GW. The interest packet has a prefix identifying content to be retrieved and a type field indicating an interest packet. The ICN-PoA modifies the interest packet to include a type of service (TS) field having the identity of the consumer and then transmitted to the ICN-GW when the content is neither created nor cached inside the 5G network. A data packet that includes the prefix, a type field indicating a data packet and the TS field is returned from the ICN-GW. The data packet is modified by the ICN-PoA to remove the TS field and transmitted to the consumer. The interest and data packets are logged and reported to an ICN-CF for generation of charging records.

Abstract: Systems and methods of handover in an information-centric network are described. The ICN-CF receives an update request from an ICN ICN-AMF indicating handover of a UE from a source NG-RAN to a target NG-RAN. The ICN-CF transmits, to an ICN router, an update request to update a PIT and/or FIB table to enable data communications with the UE after handover. The request includes the UE and target NG-RAN, and if the source and target ICN-PoA are different, the source and target ICN-PoA and the ICN-GW.
