Patent number: 9826527Abstract: This application pertains to systems, apparatus and methods for decreasing interference in wireless networks caused by User Equipments (UEs) entering compressed mode. Under certain generally accepted communication protocols, a UE can transmit at a higher power relative to normal transmissions when it enters compressed mode. These high power transmissions can cause interference both for UEs within the same cell (e.g., small cells or macrocells) as well as for UEs in neighboring cells. This interference can be minimized by using the presently disclosed systems, apparatus and methods to schedule time slots for UEs to go into compressed mode such that the distance in time between any two UEs going into compressed mode across one or more neighboring cells is maximized. By spreading out the interference effect of UEs going into compressed mode over time, overall interference in the wireless network can be decreased.Type: GrantFiled: October 31, 2014Date of Patent: November 21, 2017Assignee: Cisco Technology, Inc.Inventor: Sushanth Chandappa Kulal

Patent number: 9810759Abstract: A closed-loop calibration scheme is configured to allow a device to remain in continuous operation. A signal generator device provides a pseudorandom sequence for a signal received by a magnetic field magnetic field sensor, such as a Hall-effect sensor. A signal decoder circuit receives the output signal and decouples the generated spread spectrum signal from the interference by measuring the gain in the overall signal. The decoder device distinguishes the known spread spectrum signal from any perturbation effects of particular bandwidths. A processing circuit then outputs a signal that has an operation parameter that has been adjusted to compensate for the perturbation effects. The processing circuit provides the receiver circuit with the compensation signal, hence forming a closed-loop calibration configuration.Type: GrantFiled: January 14, 2016Date of Patent: November 7, 2017Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Arup Polley, Russell Melvin Rosenquist, Terry Lee Sculley

In one embodiment, location identification services are provided via a gateway device using data extracted from a wireless signal. The data is used to estimate a location of a device (based on comparison to previously gathered and/or reference data). In another embodiment, infrared (IR) or other short range wireless signals are broadcast from the client devices to a set-top-box (STB), and the STB or gateway correlates the signals to a location within the premises. A profiling process is used to establish specific locations within a premises, and associate location-specific services therewith.Type: GrantFiled: October 9, 2014Date of Patent: October 10, 2017Assignee: TIME WARNER CABLE ENTERPRISES LLCInventors: Peter Stern, Chris Cholas, Roger Graham Stafford

Patent number: 9787439Abstract: A data transmitting method applied with HARQ for transmitting data from a data transmission side to a data reception side. The data transmission side allocates a process, which is a transmission unit of the same data, to new transmission data and transmits the new transmission data, cyclically continues to transmit the same data of the new transmission data or an error correction code of the same data in a process same as the process until generation of another new transmission data, and allocates, when another new transmission data is generated, the process of the cyclically continued transmission to the other new transmission data and cyclically transmits the other new transmission data. The data reception side performs data combination by the HARQ using the received data to normally receive data and detect a data error or data non-reception and monitors a communication connection state with the data transmission side.Type: GrantFiled: November 28, 2014Date of Patent: October 10, 2017Assignee: Mitsubishi Electric CorporationInventor: Masaaki Kusano

Patent number: 9781763Abstract: Embodiments of the present invention relate to a radio link reestablishment method and a controller. The method includes: if after sending downlink signaling or downlink data for designated times, a controller receives no corresponding acknowledgment returned by a user equipment in a cell dedicated channel state, or the controller receives a radio link failure indication message sent by a base station corresponding to the user equipment, the controller instructs the user equipment to re-search for a cell to trigger a cell update procedure, thereby improving reliability of a communications service, and ensuring normal running of the communications service.Type: GrantFiled: December 24, 2013Date of Patent: October 3, 2017Assignee: Huawei Technologies Co., Ltd.Inventors: Zhichao Shen, Qinwen You, Yong Liu

Patent number: 9779394Abstract: One or more devices may receive multiple data records from a sensor device when the sensor device receives an indication from a network device, associated with a service provider network, to provide the multiple data records via the service provider network. Each of the multiple data records may include analytics data collected by the sensor device. The one or more devices may store the multiple data records; receive, from a client device, a data request for one or more of the multiple data records meeting particular criteria; form, based on receiving the data request, processed data including the one or more of the multiple data records meeting the particular criteria; and provide the processed data to the client device.Type: GrantFiled: May 15, 2013Date of Patent: October 3, 2017Assignee: Cellco PartnershipInventors: Tracy J. Smith, Donna L. Polehn

Patent number: 9781663Abstract: Systems and methodologies are described that facilitate efficient cell acquisition in a wireless communication system. In one aspect, a reference signal for use in cell acquisition can be constructed in a bandwidth-agnostic manner such that it contains a common central portion in a predetermined frequency band that is independent of a bandwidth utilized by an associated wireless communication system. The central portion can be constructed as a two-dimensional block in time and frequency that spans a default cell search bandwidth, a predetermined bandwidth specified by synchronization codes or other signals, or another suitable bandwidth. A reference signal can then be constructed form the central portion by tiling or expanding the central portion such that it spans the entire system bandwidth.Type: GrantFiled: August 26, 2014Date of Patent: October 3, 2017Assignee: QUALCOMM IncorporatedInventors: Juan Montojo, Byoung-Hoon Kim, Durga Prasad Malladi, Tao Luo

Patent number: 9780900Abstract: UE that are able to cancel interference from CRS, a PDSCH, a PDCCH, or a PCFICH may do so without explicitly signaling the capability to the serving eNB. The serving eNB may transmit to the UE a plurality of cell identifiers to indicate from which cells interference should be canceled. The UE receives CRS, PDSCH, PDCCH, or PCFICH from the serving eNB and cancels CRS, PDSCH, PDCCH, or PCFICH interference, respectively from the signal received from the eNB. The UE cancels the interference from the cells that correspond to the cell identifiers. The UE may then transmit a report to the eNB with a quality measurement without the interference.Type: GrantFiled: September 25, 2014Date of Patent: October 3, 2017Assignee: QUALCOMM IncorporatedInventors: Aleksandar Damnjanovic, Juan Montojo
