  • Publication number: 20170064531
    Abstract: Visual information from camera sensors can be used to assign scheduling and/or transmission parameters in a wireless network. For example, the visual information can be used to visually discover a user equipment (UE) prior to initiating link discovery. This may be accomplished by analyzing the visual information to identify an absolute or relative position of the UE. The positioned may then be used to select antenna configuration parameters for transmitting a discovery signal, e.g., direction of departure (DoD), angle of departure (AoD), precoder. As another example, the visual information is used to predict a link obstruction over a radio interface between a UE and an AP. In yet other examples, the visual information may be used for traffic engineering purposes, such as to predict a traffic density or pair UEs with APs.

  • Publication number: 20170055276
    Abstract: A hierarchical link scheduling system and method is provided. A central controller gathers network information, including global parameters and long term demands, and determines an initial schedule for link activation based on these variables. A scheduler receives the initial schedule and modifies the initial schedule based on local parameters, inter-schedule negotiation, or other short term or localized requests. The scheduler activates the links according to the modified schedule. Accordingly, the scheduler can be responsible for modifying the initial schedule provided by central controller with localized or short term requests or demands, and providing the necessary parameters to enable link activation between nodes according to the modified schedule.

  • Publication number: 20170019817
    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.

  • Publication number: 20160381665
    Abstract: Dynamic point selection (DPS) can be implemented using access points having partial or no DPS synchronization. Specifically, a mobile device may broadcast a bounce back message to access points participating in DPS transmissions to signal that a data segment has been successfully received and/or decoded by the mobile device. The bounce back message may cause the access points to drop remaining packets corresponding to the data segment from their buffers without sending those remaining packets over their respective radio interfaces. The bounce back message may be broadcast over any wireless signaling channel, such as via radio link control (RLC) signaling. Moreover, different priorities may be assigned to encoded packets intended for DPS transmission based on whether the encoded packets are communicated over a primary or secondary backhaul path.

  • Publication number: 20160366623
    Abstract: Predicting mobile station migration between geographical locations of a wireless network can be achieved using a migration probability database. The database can be generated based on statistical information relating to the wireless network, such as historical migration patterns and associated mobility information (e.g., velocities, bin location, etc.). The migration probability database consolidates the statistical information into mobility prediction functions for estimating migration probabilities/trajectories based on dynamically reported mobility parameters. By example, mobility prediction functions can compute a likelihood that a mobile station will migrate between geographic regions based on a velocity of the mobile station. Accurate mobility prediction may improve resource provisioning efficiency during admission control and path selection, and can also be used to dynamically adjust handover margins.

  • Publication number: 20160353271
    Abstract: It is possible to achieve fast high-frequency link discovery by communicating location parameters identifying a spatial location of a mobile device over a low-frequency interface to a low-frequency access point (AP). The location parameters are then used to identify antenna configuration parameters (e.g., precoders, etc.) for communicating discovery signals between the mobile device and a high-frequency access point. In one embodiment, the low-frequency AP relays the location parameters to the high-frequency AP, which uses the spatial location of the mobile device to perform link discovery. In another embodiment, the low-frequency AP communicates high-frequency antenna configuration parameters to the mobile device over the low-frequency interface.

  • Patent number: 9503208
    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.

  • Patent number: 9380487
    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.
