  • Patent number: 10039112
    Abstract: Upon receiving a request for a virtual network and before admitting the requested virtual network, a virtual service provider controller may assess the ability of the virtual service provider network to meet conditions specified in the request. In particular, the virtual service provider controller may consider details of the traffic expected in the requested virtual network in the context of existing traffic on the virtual service provider network. Consideration may be given to geographic distribution of traffic, type of traffic, and key performance indices. Indeed, traffic of different types may be homogenized through the use of weighting factors to simplify the assessment. Upon determining that the virtual service provider network may not be able to meet the conditions, the virtual service provider controller may attempt to obtain additional resources from an infra-structure provider network or may attempt to adjust resources allocated to already admitted virtual networks.

  • Publication number: 20180205418
    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.

In one example, a method includes generating a near-optimal power pattern for PC and scheduling in accordance with long term channel statistics. The near-optimal PC solution may be generated by first generating a set of possible power patterns in accordance with likely scheduling scenarios, then statistically narrowing the set of possible power patterns to identify the most commonly used power patterns, and finally selecting one of the most commonly used power patterns as the near-optimal power pattern. In another example, a table of optimal PC solutions are provided for performing distributed PC and scheduling in an adaptive and/or dynamic manner.
