  • Patent number: 11018702
    Abstract: A multi-radio access technology (RAT) circuit is provided. The multi-RAT circuit includes a radio frequency (RF) circuit(s) coupled to an interconnect medium(s). The RF circuit(s) includes a power head circuit configured to receive a local oscillation (LO) pilot and an RF signal via the interconnect medium(s). The power head circuit generates an LO signal based on the LO pilot without requiring a synthesizer. Accordingly, the power head circuit modulates the RF signal to a carrier band based on the LO signal for transmission in a millimeter wave (mmWave) spectrum. By generating the LO signal and modulating the RF signal to the carrier band in the power head circuit, it may be possible to minimize attenuation and/or interference to the RF signal. Further, it may also be possible to share the interconnect medium(s) with existing RATs, thus helping to reduce size, power, and cost impacts associated with supporting an mmWave RAT.

  • Patent number: 10856165
    Abstract: A communication device is arranged to operate in a cellular communication system and report Channel State Information, CSI, including a channel quality by a Channel Quality Indicator, CQI, which reports a CQI set. The communication device comprises a receiver arranged to receive antenna-specific reference signals, a channel estimator arranged to evaluate channel conditions from the reference signals to determine values of a CQI set, a reporting processor arranged to determine whether a bounded differential reporting format prevents values of the CQI set to be accurately reported, and to determine a CQI set such that the bounded differential reporting format allows the values of the CQI set to be reported to reduce under-reporting or over-reporting errors that arise from the use of the bounded differential reporting format, and to form a CSI report including the values of the CQI set using the bounded differential reporting format, and a transmitter arranged to send the CSI report.

  • Patent number: 10827335
    Abstract: A self-learning 5G cognitive emergency-management system responds to a triggering condition by instructing a network to open an ad hoc channel to Internet of Things (IoT) devices associated with a mass assembly of users. The system begins tracking the movements of the assembly members by performing trilateration procedures on each user's IoT device. Using artificial intelligence or cognitive analytics, the system identifies and correlates patterns in the aggregated movements of the assembly with other tracked parameters received from the IoT devices and with contextual information retrieved from extrinsic sources. The system infers aggregated user sentiment from these correlations and determines whether the movements or sentiment suggest that an unexpected event is having an adverse impact on the assembly. If so, the system takes corrective action, such as notifying an emergency-management resource or transmitting information or instructions to the assembly members.
