    Abstract: Systems and methods are disclosed for providing base station localization. In one embodiment the system includes a network including a base station such as a 5G gNodeB (gNB); a Hetnet Gateway (HNG) in communication with the gNB, wherein the HNG includes a location server and wherein the HNG virtualizes and abstracts a collection of base stations and provides a complex network under its purview as a simple base station to a mobile packet core network; a plurality of Hyper Sync Network (HSN) nodes in communication with the gNB and the HNG, wherein the plurality of HSN nodes listen to User Equipments (UEs) to locate the UEs and to synchronize clocks on the gNB with the collection of HSN nodes or other gNBs; and an Evolved Serving Mobile Location Center (E-SMLC) server in communication with the HNG and for reporting the location of a UE.

    Abstract: A method is disclosed of providing a 5G network location service, comprising: receiving, at a gNodeB, a measurement request from a Location Management Function (LMF) device; initiating, by the gNodeB in response to receiving the measurement request, a location determining SRS; sending, by the gNodeB, a Sounding Reference Signal (SRS) schedule to a master Hyper Speed Network (HSN) node; receiving, by the gNodeB, a message having the User equipment (UE) location; and using, by the gNodeB, the UE location as an NG-Radio Access Network (NG-RAN) Access Point location in a measurement response.

    Abstract: A gateway for X2 interface communication is provided, including: an X2 internal interface for communicating with, and coupled to, a plurality of radio access networks (RANs); and an X2 external interface for communicating with, and coupled to, a destination outside of the plurality of RANs, the X2 external interface further including a single X2 endpoint for the plurality of radio access networks, such that the X2 external interface provides a single interface for an external macro cell or core network to interact with the plurality of radio access networks. The gateway may further include a handover module for maintaining X2 signaling associations and transactions for incoming and outbound handovers, including X2 to S1 and S1 to X2 translation.

    Abstract: Systems and methods are disclosed to address inter-cell interference in a heterogeneous network. In one embodiment, a system is disclosed, comprising: a coordinating node situated between a radio access network and a core network; and a first base station in the radio access network in communication with the coordinating node, wherein: the coordinating node has a coordinating scheduler with a first scheduling period; the first base station has a first base station scheduler with a second scheduling period shorter than the first scheduling period; the coordinating scheduler is configured to send a resource reservation list and a resource restriction list to the first base station scheduler once during each first scheduling period; and the first base station is configured to receive the resource reservation list and the resource restriction list and to use the resource reservation list and the resource restriction list when performing mobile device resource scheduling.

    Abstract: A method for topology hiding is disclosed, comprising: receiving, at a gateway, the gateway positioned between a core network and a radio access network, a configuration information request from a base station; analyzing, at the gateway, a topology of the radio access network, the radio access network including the base station; grouping, at the gateway, the base station into a first group based on the topology; sending, from the gateway to the base station, a grouping message to indicate that the base station be placed in the first group; and terminating connections from the core network to one or more base stations in the first group at the gateway as a back-to-back proxy, thereby hiding the topology of the radio access network from the core network.
