  • Publication number: 20160173218
    Abstract: Base stations (BSs) can remove inter-BS interference components from received uplink signals using downlink information communicated over a backhaul network. The downlink information is associated with downlink transmissions of neighboring base stations, and is used to remove the inter-BS interference in accordance with interference cancellation techniques, e.g., signal interference cancellation (SIC), etc. The downlink information includes information associated with downlink transmission of the interfering BSs, such as information bits (e.g., data), parity information, control information, modulation and coding scheme (MCS) parameters, forward error correction (FEC) parameters, and other information. Additionally, inter-BS interference can be suppressed using channel information of interference channels using interference suppression techniques, e.g., interference rejection combining (IRC), etc.

  • Publication number: 20160150460
    Abstract: Methods and apparatus optimize settings of a wireless communication network via an abstractor. The abstractor receives an event sent by the wireless communication network. The abstractor receives one or more proposed settings from one or more optimizers of the wireless communication network. The abstractor transmits one or more predicted values to the one or more optimizers. The predicted values predict the effect that the one or more proposed settings will have on the wireless communication network.

  • Patent number: 9344123
    Abstract: Historical decoding in accordance with signal interference cancellation (SIC) or joint processing may reduce the amount of data that is re-transported across a network following an unsuccessful attempt to decode a data transmission. In one example, historical decoding is performed in accordance with interference cancellation by communicating information related to interfering data (rather than information related to serving data) following a served receiver's unsuccessful attempt to decode an interference signal. The information related to the interfering data may be the information bits carried by the earlier interfering data transmission or parity information (e.g., forward error correction (FEC) bits, etc.) related to the earlier interfering data transmission.

  • Publication number: 20160050670
    Abstract: Embodiments are provided for assessing radio resource requirements using virtual bin virtualization. An embodiment method includes receiving a service request from a user equipment (UE) in a geographical bin. Resource requirements are then obtained, from a lookup table (LUT), for a serving radio node and neighbor radio nodes associated with the geographic bin of the UE. The LUT comprises a plurality of entries that map combinations of path losses of wireless links for the serving radio node and neighbor radio nodes to corresponding combinations of resource requirements. The entries of the path losses further include one or more service specific and network node parameters for the serving radio nodes and neighbor radio nodes, which are also mapped to the resource requirements. The obtained resource requirements are then assessed, including deciding whether to serve the UE according to the resource requirements and to resource availability.

  • Patent number: 9264900
    Abstract: Fast mobile device authentication can be achieved during inter-domain handovers between administrative domains operating under a federated service agreement using pseudonym identifications (PID). Specifically, the mobile device may derive a PID when obtaining authentication in a first wireless network, and then use the PID to obtain fast authentication in a second wireless network. The PID may be generated during an Elliptic curve Diffie-Hellman (ECDH) authentication procedure using public keys associated with the mobile device and the first wireless network. The PID (or a derivative thereof) may then be provided to an authentication server in a second wireless network for validation. The PID may be validated by the second authentication server via online or offline validation procedures. The PID can also be used as an electronic coupon for accessing the second network.

  • Publication number: 20160037379
    Abstract: Embodiments are provided for traffic scheduling based on user equipment (UE) in wireless networks. A location prediction-based network scheduler (NS) interfaces with a traffic engineering (TE) function to enable location-prediction-based routing for UE traffic. The NS obtains location prediction information for a UE for a next time window comprising a plurality of next time slots, and obtains available network resource prediction for the next time slots. The NS then determines, for each of the next time slots, a weight value as a priority parameter for forwarding data to the UE, in accordance with the location prediction information and the available network resource prediction. The result for the first time slot is then forwarded from the NS to the TE function, which optimizes, for the first time slot, the weight value with a route and data for forwarding the data to the UE.

  • Publication number: 20150373687
    Abstract: Spoofed radio control signaling instructions can be used to dynamically adapt management of the radio interface by radio control processors. More specifically, spoofed radio control signaling can be communicated to an accelerator application instantiated on a device-side of a radio control processor. The accelerator application can pre-process the spoofed radio control signaling before forwarding the instructions to a generic radio control processor. In one example, the generic radio control processor has a universal configuration that is capable of being adapted to different telecommunication protocols based on the spoofed radio control signaling. In another example, the spoofed radio control channel signaling is translated into control instructions at the accelerator application, which are forwarded to the generic radio control processor. The control instructions govern processing of downlink data channel transmissions and/or specify parameters of uplink transmissions.

  • Publication number: 20150032495
    Abstract: Embodiments are provided to enable a user controlled path selection for servicing content requests from users. In an embodiment, a user device sends a cost request for a service to a network, and in return receives cost information for the service from the network. The user device then determines, according to the cost information, cost for one or more paths across the network. Upon determining acceptable cost for a path from the paths, the user device selects the path for receiving the service. In another embodiment, a network node coupled to links receives loading information from neighbor nodes coupled to neighbor links, and evaluates cost using loading information for the links and the received loading information for the neighbor links. When the network node receives a cost request from a user for a service, the node returns cost information for the service.

  • Publication number: 20140308962
    Abstract: Embodiments are provided for a location-based network discovery and connection establishment, which take advantage of location/positioning technology of user equipment (UE) and resolve issues above of the blind search approaches. The location-based network discovery and connection establishment schemes use UE location information and a network access MAP to speed up network discovery, and remove the need for continuous search and measurement by the UE. The schemes also reduce the search space. A wireless network access map (MAP) is provided to the UE. The UE uses the MAP information with UE current location information to reduce the search space and speed up network discovery and radio connection establishment with the network. Network operators can use this network access MAP to control the network access and manage the network load distribution. The network access MAP can be customized for each UE.
