  • Patent number: 10296602
    Abstract: Methods, apparatus, systems, and computer-readable media for assigning a real-time clock domain timestamp to sensor frames from a sensor component that operates in a non-real-time time-domain. In some implementations, a real-time component receives capture instances that each indicate capturing of a corresponding sensor data frame by the sensor component. In response to a capture output instance, the real-time component or an additional real-time component assigns a real-time timestamp to the capture output instance, where the real-time timestamp is based on the real-time clock domain. Separately, a non-real-time component receives the corresponding sensor data frames captured by the sensor component, along with corresponding metadata. For each sensor data frame, it is determined whether there is a real-time timestamp that corresponds to the data frame and, if so, the real-time timestamp is assigned to the sensor data frame.

  • Patent number: 10014568
    Abstract: Embodiments described herein relate a mobile communication device and techniques to suppress deterioration of antenna characteristics. The mobile device includes metallic members that are disposed around, or in portions of a casing of the mobile device. The metallic member is grounded directly to a ground plane of the mobile device at a first predetermined position. The grounded metallic member forms a stub line that cancels a flow of electric current though the metallic member. Furthermore, the metallic member is also connected to the ground plane, at a second predetermined location, via a resonant circuit. The mobile device is capable of adjusting a phase of the antenna current flowing through the device, when the mobile device is being operated by a user, and thus suppresses deterioration of antenna characteristics in certain desired frequency bands.

  • Patent number: 10004011
    Abstract: In a cellular communications network, a measurement report is requested to enable handover conditions to be established. In one approach, a measurement report is based on satisfaction of an event. Signalling for this measurement report includes one or more parameters on the basis of which the event is defined, including a trigger time defining a time period over which the event should be satisfied for the report to be triggered. In one approach, speed dependent scaling is applied to a parameter other than the trigger time, in the defined event. In another approach, a handover scenario, concerning the nature of the cell in which the user equipment is operational, and optionally that of a neighboring cell, governs the definition of a trigger event.

  • Patent number: 9998169
    Abstract: A phase rotator corrects the IQ imbalance in a wireless transceiver. The phase rotator is a part of a compensation system that detects and separates reception impairment images from transmission impairment images. The disclosed phase rotator introduces a phase shift between the transmission channel and the reception channel without perturbing the phase mismatch and the gain mismatch in the reception path. The phase rotator includes a first local oscillation (LO) circuit that generates a first LO signal at a first carrier frequency and a second LO circuit that generates a second LO signal at a second carrier frequency that deviates from the first carrier frequency for a phase rotation period. The phase rotation period is sufficiently long such that the frequency deviation can introduce a prescribed phase shift between the first LO signal and the second LO signal.

  • Patent number: 9948276
    Abstract: In a high-frequency module, first and second inductors that adjust attenuation characteristics of a first filter of a filter component, are separated from each other such that the first and second inductors readily magnetic field couple with each other. Consequently, an amount of wiring used to define a first wiring electrode inside the filter component is reduced and a number of layers of a package substrate and the profile of the filter component are reduced. Consequently, variations in the attenuation characteristics of the first filter caused by the first wiring electrode electromagnetic-field coupling with another wiring electrode are prevented. The attenuation characteristics of the first filter is easily adjusted and improved by adjusting the inductance value of the second inductor.

  • Patent number: 9912441
    Abstract: The present invention relates to a device and a system for transmitting data messages which can be received by different types of receivers. A device and system are disclosed where data transmissions are based on data messages (2) comprising two parts, a first part (20) being encoded in accordance with a communication protocol, such as the wireless MBus protocol, and a second part (21) which comprises error-correcting information for enabling a receiver device to correct errors in the data message (2), such as parity information related to turbo coding. The first part (20) forms an independent sub data message which can be received independently of the content of the second part (21). The sub data message can be received as is within a first communication range (6), and the entire data message can by virtue of the error correction information, and subsequent error correction, be received within a second longer communication range (7).

  • Patent number: 9906280
    Abstract: A closed loop MIMO feedback system is described in which the number of available antenna ports is less than the number of antenna elements. In one implementation, sounding reference signals, received from a number of UEs, may be used, by a base station, to generate and transmit a number of OFDMA Channel State Information Reference Signals (CSI-RSs). The OFDMA CSI-RSs may be determined based on the top eigen beams associated with an average channel covariance matrix determined based on the received sounding reference signals. A UE, in response to receiving the OFDMA CSI-RSs, may determine a preferred eigen beam and transmit a quantized version of the preferred eigen beam back to the eNB. Subsequent communications with the UE may be made using beamforming techniques that are based on the quantized version of the preferred eigen beam.
