  • Publication number: 20160353281
    Abstract: An aspect of the disclosure provides a method of admitting a session from a user device subscribed to a service with a virtual network operator. The method includes receiving a service request from said user device at an Access Point and selecting a network function Authentication and Authorization (AA) function (AAF) to confirm the user device is authorized for the requested service, and transmitting the request to the selected network function AAA function. The AAAF which processes the request may reside with the virtual network operator (VNO). However, the VNO may share its AAA database with other network entities (for example, Telecom Connectivity Service Providers (TCSPs) or InPs), and allow those entities to perform the AAA functions.

  • Patent number: 9485792
    Abstract: Methods and systems for providing efficient communications between two mobile stations served by the same base station or relay station are provided. A base station maintains information identifying which mobile stations it is serving. When a connection is set up between two mobile stations, if they are both being served by the same base station, the base station forwards traffic directly between the two mobile stations without forwarding it on to higher level network entities.

  • Publication number: 20160286568
    Abstract: Inter-cell interference can be reduced by re-assigning uplink scheduling responsibilities for a user equipment (UE) from a controller associated with a serving access point (AP) to a controller associated with a neighboring AP, as the controller associated with the neighboring AP may have better access to channel information corresponding to interference experienced by the neighboring AP as a result of uplink transmissions from the UE. After the re-assignment, the controller associated with the neighboring AP may independently schedule an uplink transmission parameter (e.g., a transmit power level, a modulation coding scheme level and/or a precoder) of the UE in a manner that mitigates inter-cell-interference in the neighboring cell.

    Abstract: Methods and systems for providing joint power control (PC) and scheduling in a wireless network are provided. 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.

  • Patent number: 9455919
    Abstract: Interference costs on virtual radio interfaces can be modeled as a function of loading in a wireless network to estimate changes in spectral efficiency and/or resource availability that would result from a provisioning decision. In one example, this modeling is achieved through cost functions that are developed from historical and/or simulated resource cost data corresponding to the wireless network. The cost data may include interference data, spectral efficiency data, and/or loading data for various links over a common period of time (e.g., a month, a year, etc.), and may be analyzed and/or consolidated to obtain correlations between interference costs and loading on the various links in the network. As an example, a cost function may specify an interference cost on one virtual link as a function of loading on one or more neighboring virtual links.

  • Patent number: 9455772
    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.

  • Publication number: 20160278027
    Abstract: A controller having access to channel information associated with a neighboring access point (AP) may communicate a mask to a served user equipment (UE). The mask may specify transmission parameters for an uplink transmission between the served UE and a serving AP such that a successful decoding probability of the uplink transmission at the neighboring AP exceeds a threshold. The mask may specify a maximum MCS level for the uplink transmission, a minimum transmit power level for the uplink transmission, and/or a precoder constraint for the uplink transmission that produces constructive interference at a spatial location of the neighboring AP. This may enable the neighboring AP to isolate the uplink transmission from uplink wireless signals using an interference cancellation technique, e.g., successive interference cancellation (SIC) techniques.

  • Publication number: 20160255581
    Abstract: Cell switch-off (CSO) methods for base stations (BSs) in a wireless network are provided. The CSO methods utilize quality of service (QoS) requirement information of user equipments (UEs) to determine which BS to switch off according to a pre-defined criteria. The criteria is defined so that impact of switching off a BS on the UEs may be reduced, and/or QoS requirements of at least some of the UEs may be satisfied if a BS was switched off.

  • Publication number: 20160255568
    Abstract: A wireless communication access path exists between an ingress station and an egress station. A logical communication tunnel is established between the ingress and egress stations directly or through any number of intermediate relay stations to handle session flows of PDUs. As PDUs arrive, the ingress station may determine and add information bearing on an identified QoS associated with the PDU to the PDUs before they are delivered to the downstream egress station(s) or intermediate relay station(s). The information may be used by the downstream stations to schedule the PDUs for further delivery. The information may also be used by the egress station to schedule the PDUs for delivery.
