    Abstract: Embodiments of the disclosure provide methods and systems for sidelink resource allocation in user equipment (UE) groups. The method includes, receiving, by a UE, from a radio access network (RAN) node, a first resource configuration message including configuration information for sidelink resources indicated by a sidelink resource grant and conditions for using sidelink resources of the sidelink resource grant. The method further includes receiving, from a second UE of the UE group, a second sidelink resource configuration message, the second sidelink resource configuration message including an activation indicator to activate at least a portion of the sidelink resources indicated by the sidelink resource grant. The method further includes determining the sidelink resources to be used for sidelink transmissions by combining the first and second sidelink resource configuration messages. The method further includes using the determined sidelink resources for data transmissions.

    Abstract: An apparatus receives an indication of a set of geographic zones and a set of control transmission wireless resource units. For each one of the geographic zones, corresponding control transmission wireless resource unit are specified for use while in that the geographic zone. While in a first zone of the geographic zones, a control transmission is transmitted, reserving a first data transmission wireless resource unit for use by the apparatus for sidelink (SL) data communication. The control transmission is performed using control transmission wireless resource units corresponding to the first zone. The data transmission wireless resource unit is selected from a pool of data transmission wireless resource units and each member of the pool of data transmission wireless resource units is available for use across a set of geographic zones. Different members of the pool of data transmission wireless resource units are concurrently.

    Abstract: Systems and methods for network functions virtualization (NFV)-management and orchestration (MANO) are provided where a virtualized network function (VNF)-forwarding graph (FG) including a plurality of VNFs is generated based on a customer request. The plurality of VNFs are instantiated at corresponding NFV infrastructure (NFVI)-points of presence (PoPs). A network service (NS) request including the generated VNF-FG may be constructed and added to a NS catalog.

    Abstract: An embodiment of a method for network resource management comprises performing joint traffic engineering and physical layer power control on a controller and using a routing and power control optimization process that comprises a combined alternating direction method of multipliers (ADMM) process and a power management process. First and second commands are generated at the controller according to optimization parameters determined by the routing and power control optimization process. The first and second commands are transmitted from the controller to nodes connected to the controller. The first commands are for modifying transmission parameters for links between nodes and the second commands are for modifying transmission parameters for connections between nodes and user devices.

    Abstract: Wireless network specific (WN-specific) key can be used to provide access protection over the radio access link. A WN-specific key may be associated with (or assigned to) a wireless network, and distributed to access points of the wireless network, as well as to user equipments (UEs) following UE authentication. The WN-specific key is then used to encrypt/decrypt data transported over the radio access link. The WN-specific key can be used in conjunction with the UE-specific keys to provide multi-level access protection. In some embodiments, WN-specific kays are shared between neighboring wireless networks to reduce the frequency of key exchanges during handovers. Service-specific keys may be used to provide access protection to machine to machine (M2M) services. Group-specific keys may be used to provide access protection to traffic communicated between members of a private social network.

    Abstract: Aspects of this disclosure provide techniques for dynamically configuring flow splitting via software defined network (SDN) signaling instructions. An SDN controller may instruct an ingress network node to split a traffic flow between two or more egress paths, and instruct the ingress network node, and perhaps downstream network nodes, to transport portions of the traffic flow in accordance with a forwarding protocol. In one example, the SDN controller instructs the network nodes to transport portions of the traffic flow in accordance with a link-based forwarding protocol. In other examples, the SDN controller instructs the network nodes to transport portions of the traffic flow in accordance with a path-based or source-based transport protocol.
