20090199265 | ANALYTICS ENGINE - Aspects of the subject matter described herein relate to a mechanism for assessing security. In aspects, an analytics engine is provided that manages execution, information storage, and data passing between various components of a security system. When data is available for analysis, the analytics engine determines which security components to execute and the order in which to execute the security components, where in some instances two or more components may be executed in parallel. The analytics engine then executes the components in the order determined and passes output from component to component as dictated by dependencies between the components. This is repeated until a security assessment is generated or updated. The analytics engine simplifies the work of creating and integrating various security components. | 08-06-2009 |

20110197277 | SYSTEM AND METHOD FOR PRIORITIZING COMPUTERS BASED ON ANTI-MALWARE EVENTS - Tracking malware state information assigned to computers in an enterprise network is described. A computer may transition from a current malware state to a new malware state in accordance with a plurality of stored rules and detection of an anti-malware event on the computer. Examples of anti-malware events include, but are not limited to, detection of new malware on the computer or cleaning of the computer. The malware state information for computers on the network may be mapped to a risk level representing an amount of risk that infected computers present to other computers on the network. The results of a risk level assessment for the computers on the network may be output via a user interface to enable an administrator of the network to prioritize servicing of computers with detected malware. | 08-11-2011 |

20090274253 | JOINT ESTIMATION OF MIMO CHANNELS AND NOISE CORRELATION FOR WIRELESS SYSTEMS WITH MULTIPLE RECEIVE ANTENNAS - A radio communication sent by a transmitter having M transmit antennas is received by a receiver having N receive antennas, where M is a positive integer greater than or equal to one and N is positive integer greater than one. Thus, N output signals, one for each receive antenna, are received. The signal transmitted from each transmit antenna includes predetermined pilot symbols known by the receiver and information symbols to be determined by the receiver. Weights for estimating each of M×N single-input/single-output channels between transmit and receive antennas are determined based on jointly processing pilot symbols received on all of the N receive antennas. The M×N channels are estimated based on the determined weights, and those estimated channels are used to determine the information symbols. An iterative procedure is used to estimate the M×N channels using a noise correlation matrix estimate and to estimate the noise correlation matrix using the M×N channel estimates. | 11-05-2009 |

20090069054 | Method and Apparatus for Linearly Precoding Downlink Transmissions to Reduce Temporal Variations in Interference - According to one or more method and apparatus embodiments taught herein, network base stations reduce temporal variations in the interference perceived by mobile stations operating within the network by slowing down the rate at which they change or otherwise update the linear precoding settings applied to their transmitted Orthogonal Frequency Division Multiplex (OFDM) signals in comparison to the rate at which the base stations perform link adaptation. That is, the precoding-related component of measured interference (e.g., other-cell interference) at the mobile stations is made quasi-stationary with respect to channel quality reporting and link adaptation intervals by fixing the preceding settings used by each base station over time intervals substantially longer than the channel reporting/link adaptation intervals. | 03-12-2009 |
20090103558 | Hybrid Contention-Based and Schedule-Based Access to a Communication Link - One or more embodiments taught herein provide a hybrid access arrangement using a contention-based channel and a scheduled channel on a communication link. As a point of significant efficiency, given users transmit autonomously on the contention-based channel, without need for scheduling overhead. However, if a contention overload occurs on the contention-based channel, the involved users are identified from unique signature sequences included in their user transmissions. The identified users are temporarily managed as scheduled users on the scheduled channel, which supplements the contention-based channel and therefore may use limited communication link resources in comparison to the contention-based channel. Users not involved in the contention overload generally continue operating on the contention-based channel. | 04-23-2009 |
20120058767 | SIGNALING SUPPORT FOR ANTENNA SELECTION USING SUBSET LISTS AND SUBSET MASKS - A communication device is described herein that has control (or at least partial control) over which virtual antenna(s) in one or more base stations to use for transmissions. In one embodiment, the mobile phone performs the following steps: ( | 03-08-2012 |
20120114060 | MULTIPLE-INPUT, MULTIPLE-OUTPUT COMMUNICATION SYSTEM WITH REDUCED FEEDBACK - In MIMO systems, two or more transmit signals are transmitted from different antenna clusters having one or more transmit antennas each. A precoding circuit weight the transmit signals transmitted from each transmit antenna using a common set of frequency independent antenna weights for all antenna clusters. The antenna weights are computed based on correlations between transmit antennas in the same antenna cluster. | 05-10-2012 |

20090111381 | METHOD AND APPARATUS FOR UTILIZING A DIRECTIONAL BEAM ANTENNA IN A WIRELESS TRANSMIT/RECEIVE UNIT - A method and apparatus for utilizing a switched beam directional antenna in a wireless transmit/receive unit (WTRU) is disclosed. A wireless communication system includes a serving cell, a neighbor cell and a WTRU. The WTRU is configured to generate and steer a directional beam in a plurality of directions. Once the WTRU registers with the wireless communication system, the WTRU receives messages transmitted by the serving cell. The WTRU measures signal quality of messages received in each of a plurality of predetermined directions while steering the directional beam antenna. The WTRU selects a particular one of the directions having the best signal quality. As the WTRU constantly moves, the WTRU monitors signal quality in the selected direction, and switches to another direction when the signal quality in a current direction drops below a predetermined threshold. | 04-30-2009 |
