  • Publication number: 20160192370
    Abstract: A base station may establish a wireless connection with a mobile device. The base station may determine an index value for each of a plurality of carriers that may be used for the wireless connection. The index value for a respective carrier may be determined based on a quantity of idle mode devices using the respective carrier in an idle mode. The base station may generate a carrier order that indicates a priority for each of the plurality of frequencies. The carrier order may be generated based on sorting the plurality of carriers based on the index values for the plurality of carriers. The base station may send order information indicating the carrier order to the mobile device via the wireless connection.

  • Patent number: 9337963
    Abstract: A transmission method for multi-antenna retransmission is provided, comprising steps of: generating the bits to be transmitted by respective antennas; mapping the bits to be transmitted by the respective antennas into symbols; and multiplying by a constant the vector constituted by the mapped symbols transmitted by multiple antennas, wherein the resulting vector is orthogonal to the matrix constituted by the symbols previously transmitted by multiple antennas, and transmitting the orthogonal symbols. According to the method of the present invention, the remapped symbols transmitted by the respective antennas and the symbols previously transmitted by the respective antennas constitute a matrix that has an orthogonal property. The orthogonal property can be used to effectively detect signals. In addition, the method has a reception algorithm with low complexity and brings about significant performance gains over conventional methods.

  • Publication number: 20160061957
    Abstract: Examples are provided that enable a cellular network location assist to confirm a position determined using a sensor of a mobile device. As a result of global positioning system signals becoming unavailable due to the mobile device traveling indoors, the mobile device implements a sensor-based position determination that provides a position of the mobile device as the mobile device travels about a location. In order to confirm the reliability of the sensor-based position determination, the mobile device, after passage of time or after traveling some estimated distance, requests location assistance indications from the cellular network. A processor of the mobile device receives the location assistance indications and generates a directional vector based on several of the location assistance indications. Using the directional vector, the processor confirms the reliability of the dead reckoning position.

  • Patent number: 9251465
    Abstract: This disclosure provides a computer-program product, system, method and apparatus for accessing a representation of a category or item and accessing a set of multiple transactions. The transactions are processed to identify items found amongst the transactions, and the items are ordered based on an information-gain heuristic. A depth-first search for a group of best association rules is then conducted using a best-first heuristic and constraints that make the search efficient. The best rules found during the search can then be displayed to a user, along with accompanying statistics. The user can then select rules that appear to be most relevant, and further analytics can be applied to the selected rules to obtain further information about the information provided by these rules.

  • Publication number: 20150242484
    Abstract: Methods, processes and computer-program products are disclosed for use in a parallelized computing system in which representations of large sparse matrices are efficiently encoded and communicated between grid-computing devices. A sparse matrix can be encoded and stored as a collection of character strings wherein each character string is a Base64 encoded string representing the non-zero elements of a single row of the sparse matrix. On a per-row basis, non-zero elements can be identified by column indices and error correction metadata can be included. The resultant row data can be converted to IEEE 754 8-byte representations and then encoded into Base64 characters for storage as strings. These character strings of even very large-dimensional sparse matrices can be efficiently stored in databases or communicated to grid-computing devices.

  • Publication number: 20150242762
    Abstract: Systems and methods for performing analyses on data sets to display canonical rules sets with dimensional targets are disclosed. A cross-corpus rule set for a given Topic can be generated based on the entire corpus of data. A first dimensional rule set can be generated based on a first context (e.g., based on the same Topic but using a first sub-domain of the corpus of data). A second dimensional rule set can be generated based on a second context (e.g., based on the same Topic but using a second sub-domain of the corpus of data). Key dimensional differentiators (e.g., for each dimension, or context, of the Topic) can be determined based on a comparison of the general rule set, the first dimensional rule set, and the second dimensional rule set. A canonical rule set visualization can be displayed. The visualization can highlight the dimensional selectors (e.g., those tokens, or nodes, that differ between the first dimensional rule set and the second dimensional rule set).

  • Patent number: 8923877
    Abstract: An approach is provided for mitigating interference from Long Term Evolution (3GPP LTE) terminals to adjacent frequency bands. A platform determines whether a region associated with transmission of one or more resource blocks are an interfering region according to predetermined criteria, where one or more resource blocks are assigned a primary carrier as a default carrier for the transmission. The platform selects a secondary carrier for the one or more resource blocks instead of the primary carrier if the region is determined to be interfering.
