    Abstract: Embodiments are provided for uplink measurement based mechanism and control using user equipment (UE) centric sounding signals. The mechanism provides an alternative to DL-measurement dominated system control. Based on UL-measurements at TPs, the network obtains knowledge of users' channel and timing information, traffic, and interference, and is thus able to perform better control, including TP and UE clustering and optimization, and power control and link adaptation. In an embodiment method, a TP receives one-to-one mapping information indicating a plurality of UE IDs and a plurality of sounding channels assigned to the corresponding UE IDs. When the TP detects a sounding reference signal (SRS) from a UE, the TP is able to identify the UE using the detected SRS and the one-to-one mapping information. The TP then obtains measurement information for the identified UE, enabling better control and communications for uplink and downlink transmissions between multiple TPs and the UE.

    Abstract: The present invention facilitates efficient and effective power management for wireless telecommunications. In one embodiment, presented approaches enable power savings in devices with a limited power supply (e.g., mobile devices operating on battery power supply, photocell, etc.). In one exemplary implementation, power smart channels facilitate power conservation. Power smart channel communications can be transmitted at lower power levels than conventional or normal channel communications. Presented power smart channel methods and systems can be implemented in a wireless cellular communication environment where power smart channels are established and used in accordance with various aspects and configurations of the components (e.g., location, remaining battery charge, multiple resource bands, etc.) in the wireless cellular communication environment.

    Abstract: There are disclosed systems, devices, and methods for distributing pre-fetch data. A parent node obtains pre-fetch data comprising at least one of: i) data expected to be of interest to a particular user, pre-fetched by the parent node from at least one data source; and (ii) at least one identifier identifying data expected to be of interest to the particular user, for pre-fetching the identified data at a child node. The parent node selects first and second subsets of the pre-fetch data for transmission, respectively, to first and second child nodes, the selecting based on at least a predicted future location of the particular user and a respective geographic location of the first and second child nodes; and transmits the first and second subsets of the pre-fetch data, respectively, to the first and second child nodes.

    Abstract: Increased resource utilization efficiency can be improved by modeling path costs during admission and path-selection. Specifically, path costs for candidate paths are modeled based on load characteristics (e.g., current load, load variation, etc.) of links in the candidate paths. Path costs can represent any quantifiable cost or liability associated with transporting a service flow over the corresponding path. For example, path costs can correspond to a probability that at least one link in the path will experience an outage when transporting the service flow, a price charged by a network operator (NTO) for transporting the traffic flow over the candidate path, or a total network cost for transporting the flow over a candidate path. The candidate path having the lowest path cost is selected to transport a service flow.

    Abstract: An aspect of the disclosure provides a method of network slice management performed by a Communication Service Management Function (CSMF). The method includes receiving service requirements and receiving capability exposure information. The method further includes transmitting network slice requirements in accordance with the service requirements and capability exposure information. In some embodiments the capability exposure information is received from a Network Slice Management Function (NSMF). In some embodiments the network slice requirements are transmitted to the NSMF. Other aspects are directed to methods implemented by an NSMF and a Network Sub-Slice Management Function (NSSMF). Other aspects are directed to the network functions themselves.
