  • Patent number: 9526020
    Abstract: Monitoring non-supported wireless spectrum within a coverage area of a distributed antenna system (DAS) in which a listening module connected to a remote unit of the DAS monitors non-supported wireless frequencies (i.e., frequencies that are outside the frequency ranges supported by the downlink and uplink signals of the DAS), via one or more antennas. The listening module also transmits the wireless frequencies to a monitoring module connected to head-end equipment (HEE) of the DAS. In that manner, a monitoring module can use an existing DAS infrastructure to monitor non-supported portions of the wireless spectrum at remote locations. In addition to avoiding the need to run a parallel DAS infrastructure, the disclosed arrangements are also useful in shared spectrum environments and other environments where efficient spectrum utilization is desired.

  • Patent number: 9521580
    Abstract: Methods and systems are provided for reducing the potential of interference between a cell tower and a neighboring EMR source. At a base station, such as an eNodeB, it is determined that a sector of the cell tower has the potential for interference with the EMR source based on, for instance, monitoring of network parameters, a computation of the sector's azimuth, and a distance between the sector and the EMR source. Time intervals are computed corresponding to when the EMR source emits EMR in a direction of the sector of the base station, Uplink and downlink transmissions to and from the sector of the cell tower are ceased during the computed time intervals.

  • Patent number: 9495673
    Abstract: The present invention provides a solution to the needs described above through a system and method for a wireless universal mobile product interface (WUMPI). Generally, products/objects have their own interface, or man-machine-interface (MMI). Technically, the wireless universal mobile product interface of the present invention (WUMPI) innovates this space by replacing the product's MMI by implementing reverse software control via wireless transmission channel and or Bluetooth wireless technologies to control the mobile device's screen—replacing the local software component on the mobile device which controls what is shown on the screen in terms of a man-machine interface (MMI). This enables a product/object within the area of the mobile device to take over control via the wireless transmission channel or other wireless capability of the mobile device and to “extend” the product interface to the mobile device that came within its control range, or the product/object's personal area network (PAN).

  • Patent number: 9383203
    Abstract: A specific emitter identification (SEI) method and apparatus is capable of identifying and tracking objects within a geographical area of interest wherein the system and method has not been preprogrammed to look for particular signals. The system and method receives all of the emitted electromagnetic signals emitted from area of interest. The system and method next performs high order statistical analysis on the received signals and determines which signals emanate from possible targets of interest and which likely emanate from background clutter/noise by comparing the relative degrees of Gaussianness of the signals (for example using entropy measurements). The least Gaussian signals are deemed to likely be signals from potential targets of interest while those which are more Gaussian are deemed to be likely from background clutter or noise.

  • Patent number: 9386505
    Abstract: A method performed by a user equipment (UE) is described. The method includes receiving a physical cell identifier information element (IE) from an evolved node B (eNB). The physical cell identifier IE is associated with a secondary cell (SCell) that is on an unlicensed Long-Term Evolution (LTE) carrier frequency. The method also includes determining a physical-layer cell identity (PCI) of the SCell based on the physical cell identifier IE. The method further includes applying the PCI as a parameter for physical channels or signals on the SCell.

  • Patent number: 9380468
    Abstract: In one embodiment a method of identifying interference in a wireless network is disclosed. The wireless network comprises a first base station and a second base station. The method comprises detecting an increase in an error rate in a wireless connection between the first base station and a first wireless device; comparing a reference signal power received by the first wireless device from the first base station with a threshold value; and determining that the increase in error rate is due to interference from a wireless connection between the second base station and a second wireless device if the reference signal power is greater than the threshold.

  • Patent number: 9350853
    Abstract: Methods and systems for monitoring communication of mobile communication terminals, such as cellular phones. An off-air monitoring system reconstructs both directions of a call conducted between two mobile terminals by receiving only downlink channels. The off-air monitoring system receives multiple downlink transmissions transmitted by base stations in a wireless communication network. The system uses the received downlink transmissions to reconstruct the bidirectional call content of calls conducted between wireless terminals. In order to reconstruct the bidirectional content of a given call, the system identifies and correlates the two downlink transmissions of that call from among the multiple received downlink transmissions.

  • Patent number: 9351304
    Abstract: Methods, systems, and devices are described for predicting a current random access transmission power detectable by a base station based on historical transmission power information. In one aspect, a mobile device may access a historical transmission power associated with a current state of the mobile device, with the historical transmission power based on mobility patterns of the mobile device. Based at least in part on the accessed historical transmission power, the mobile device may predict a current random access transmission power of the mobile device, where the predicted current random access transmission power is configured to elicit a random access response from a base station. In one aspect, the techniques described herein may reduce a number of power ramp steps taken by the mobile device during a random access procedure, reduce interference from the mobile device during the random access procedure, or both based on the predicted current random access transmission power.

  • Patent number: 9344302
    Abstract: A transceiver for orthogonal frequency division multiplex communication has a transmitter module (1) and a receiver module (2). The transmitter (1) has an l-path (3) and a Q-path (4) to receive signals on a number of subcarriers provided by a signal generator (9). The receiver module (2) has a receiver l-path (7) and a receiver Q-path (8) to deliver signals to a processor (15). IQ imbalance is calculated for each of the transmitter and receiver by the signal generator sending a sample signal (Xl(k), XQ(k)) over a one of the transmitter paths. The signal is then applied to one or each of the inputs to the receiver paths (7,8) to generate receiver output signals Yl(k), YQ(k), RQ(k). The processor (15) is responsive to the output signals to calculate the transmitter and receiver IQ imbalance for that subcarrier. A calibrator (19) and compensator (20) are responsive to the calculated IQ imbalance to correct or compensate each subcarrier of the transceiver band.
