  • Patent number: 10285177
    Abstract: System and method for automatic communication with remote devices enabling remote control and monitoring of the devices. The primary target is for low-power, remote devices running narrow or relatively narrow bandwidths, though the method is not restricted for any payload limits. The system enables two devices on a fully automated basis to identify each other, sound the radio paths between them to discover spectrum characteristics, select and exchange a vector of currently unused and optimum frequency bands for communication. Once defined, the devices use the frequency bands for automatic communication. The method enables devices to configure themselves for exchange of data and then the transfer of data. The base station and/or end points have the ability to initiate a connection and data transfer and use software defined radios to implement this capability.

  • Patent number: 10237107
    Abstract: This application proposes multi-beam antenna systems using spherical lens with high isolation between antenna ports and compatible to 2×2, 4×4, 8×8 MIMO transceivers. Several compact multi-band, multi-beam solutions (with wideband operation, 40%+, in each band) are achieved by creating dual-band radiators movable on a track around one or more spherical lenses and by placing lower band radiators between spherical lenses. By using secondary lenses for high band radiators, coupling between low band and high band radiators is reduced. Beam tilt range and side lobe suppression are improved through phase shifting and/or a rotational angle of radiators. A wide beam tilt range (0-40 degree) can be achieved via the proposed multi-beam antenna systems. Each beam can be independently tilted. Based on proposed single and multi-lens antenna solutions, cell coverage improvements and stadium tribune coverage optimization are also achieved, together with a reduction in interference.

  • Patent number: 10171144
    Abstract: A low complexity multiple input multiple output transmitter that transmits a single codeword per channel is disclosed herein. Instead of sending multiple codewords per channel for transmissions that support higher data layer transmissions, the transmitter can send single codewords over multiple channels in order to improve spectral efficiency over a range of signal to interference plus noise ratios. For instance, if a downlink transmission to a user equipment (UE) has a rank of 4, capable of supporting 4 data layers, instead of sending 2 or more codewords over a single downlink control channel, the transmitter can schedule multiple control channels and transmit a single codeword per channel. The transmitter can also include in the signaling to the UE that the multi-codewords are included in multiple downlink control channels.

  • Patent number: 10135568
    Abstract: A relaying method performed by a half-duplex relay for a telecommunications system includes a reception stage of receiving codewords from sources during N uses of the transmission channel. The successive codewords correspond to B blocks, the first of which can be decoded independently of the other blocks. This stage includes a decoding step of estimating a message from each source based on received codewords. The relay performs an error detection and decision-taking step on messages decoded without error. The relay performs a stage of encoding a signal and forwarding it to a destination. The signal is representative of only messages decoded without error and includes channel encoding by an incremental redundancy code to obtain a channel encoded codeword. The relay passes from non-selective reception to selective reception after receiving B1 blocks and switches from the reception stage to the encoding and forwarding stage under control of the decision step.

  • Patent number: 10089853
    Abstract: Companion and accessory devices can be wirelessly leashed together in a manner that enables the devices to estimate their proximities to each other. One device can periodically attempt to detect a signal from the other device. For each attempt, the attempting device can store an indication of whether the signal was detected. If a number of times that the signal was undetected exceeds a threshold, then the attempting device can perform specified operations, such as alerting a user that the wireless leash was broken. As another example, one device can detect that a strength of a signal from the other device exceeds a threshold. In response, the detecting device can measure signal strengths more frequently. If the measuring device then detects that the signal strength exceeds another threshold, then the measuring device can cause specified operations to be performed, such as data synchronization between the devices or unlocking a device.

    Abstract: A wireless relay mitigates Radio Frequency (RF) interference. A receive antenna receives RF signals over a receive frequency band. An RF receiver processes the received signals to detect and transfer RF interference levels. The processing circuitry transfers control data to a tunable RF isolator that indicates the size of a guard band between the receive frequency band and a transmit frequency band. The guard band size is selected based on the RF interference levels for the receive frequency band at the receive antenna. The tunable RF isolator attenuates RF frequencies in the tunable guard band from corresponding RF transmit signals. A transmit antenna transfers the RF transmit signals over the transmit frequency band.

  • Patent number: 9538516
    Abstract: A method is provided for allowing a user equipment to receive data in a wireless communication system. The user equipment performs blind decoding for an enhanced physical downlink channel (EPDCCH) in which a downlink control information (DCI) is transmitted. The user equipment decodes data on a physical downlink shared channel (PDSCH) by using the DCI. If the DCI does not comprise demodulation reference signal information for decoding of the PDSCH, the PDSCH is decoded by using demodulation reference signal information associated with a resource block among a plurality of resource blocks in which the DCI is transmitted.
