  • Patent number: 10367721
    Abstract: Aspects of the disclosure relate to mechanisms for interworking between legacy and next generation radio access technologies (RATs) in a communication network. In some examples, a handover from a legacy access network to a next generation access network may be performed via a next generation core network. A handover request received at a next generation core network serving node may include an identifier of a next generation target cell. The next generation core network serving node may identify another next generation core network serving node to which the handover may be forwarded based on the target cell identifier or may select the next generation access network based on the target cell identifier. The next generation core network serving node may then communicate with the next generation access network to complete the handover.

  • Patent number: 10367708
    Abstract: Embodiments are directed to transmitting network coding (NC) traffic in heterogeneous networks having both NC and non-NC nodes. A non-NC node, upon receiving the first NC encoded packet will return an error in acknowledgement to the source NC node. The source NC node maintains a table of directly neighbor nodes that indicates whether or not NC is supported. The source NC node decodes the packet for any non-NC destination node and sends the encoded packet to NC nodes per the table. For a non-NC node in the network, the source NC node will send an encoded packet and based on an acknowledgement, the table entry for that node is updated. If NC is supported, the source sends the encoded packet, otherwise it sends the decoded packet.
