    Abstract: According to one aspect of the present disclosure, a method for uplink synchronization is provided, wherein the method includes receiving, by a user equipment (UE), a radio resource control (RRC) message from a network, the RRC message comprising a first Timing Advance Group (TAG) identity (ID) and a second TAG ID different than the first TAG ID. The method also includes transmitting, by the UE, a first signal over a component carrier in accordance with a timing advance associated with the first TAG ID and a second signal over the component carrier in accordance with a timing advance associated with the second TAG ID.

    Abstract: A computing system and a method are provided for determining a network traffic routing path through a service function chain (SFC). A joint network slicing and traffic engineering problem is provided that may be solved to identify network slicing configuration and traffic engineering parameters to provide a set of function nodes, the SFC, and the network traffic routing path from the source node to the destination node. The joint network slicing and traffic engineering problem P may be solved by minimizing a resource objective associated with the joint network slicing and traffic engineering problem, in accordance with a set of one or more constraints. Instructions may be transmitted to a network orchestrator to create the service function chain in a network slice on the set of network nodes in accordance with the identified network slicing configuration and traffic engineering parameters, to provide the network traffic routing path.

    Abstract: System and method embodiments are provided for traffic engineering (TE) in software defined networking (SDN). The embodiments enable a complete end-to-end TE solution between a user equipment (UE) and a source/destination across a radio access network (RAN). In an embodiment, a method in a network component for TE in a SDN includes receiving TE information from a first core network component in a core network, a RAN component, wherein the RAN is communicably coupled to the core network, wherein the TE information includes a TE objective; and determining a TE decision between at least one UE and a second core network component in the core network according to the TE information and the TE objective, wherein the TE decision comprises information for at least one end-to-end path solution between the at least one UE and the second core network wherein the path traverses the core network and the RAN.
