  • Publication number: 20220239458
    Abstract: Methods and apparatus for implementing a repeater are described. In various embodiments the repeater determines uplink/downlink timing information either from information broadcast from a base station or from monitoring received signals and/or gaps between received signals. In various embodiments while the repeater may decode control information to determine uplink/downlink time periods, user data is not decoded and re-encoded. In various embodiments interference between uplink and downlink circuitry is reduced or minimized by controlling gains, combining weights and/or power to amplifiers in the repeater based on the mode of operation. A stored information can include sets of different weights and/or parameters for the mode of operation and/or beam forming antenna pattern in use at a given time.

  • Patent number: 11218976
    Abstract: A communications device including an array antenna assembly including a plurality of transmit chains, each with a transmit power amplifier, synchronously captures transmit power measurements for each power amplifier. A baseband transmitter in the communications device determines when a predetermined symbol in a protocol, e.g. a PSS SSB symbol, is to be transmitted and sends, e.g. via a SPI, a capture command to command each of the ADCs corresponding to the power amplifiers to synchronously capture a power measurement. Power measurements are captured at the boundary of the predetermined symbol, and the power measurements represent average transmit power levels corresponding to the symbol. The power measurements are communicated to the baseband transmitter which processes the data using calibration tables and taper information. Processed power measurements are compared to desired transmitter target levels and errors are determined. Based on the errors the gains of one or more TX chains are adjusted.

  • Patent number: 11171613
    Abstract: Controllable radio frequency power amplifiers (RFPAs), e.g., in a Hybrid-MIMO array, which are being driven at lower power levels, are operated at conditions such that their inherent EVM and ACLR are intentionally further increased. This increase of inherent EVM and ACLR is done in a precise manner, and the increased inherent EVM and ACLR are cancelled or reduced by the EVM and ACLR of the input Array DPD signal. The net result is improved EVM and ACLR performance over a broader range of angles. Exemplary methods and apparatus for increasing distortion include individual or combinations of: i) changing the DC bias a RFPA based on average operating power level; ii) changing supply voltage, e.g. Vcc, of a RFPA based on average operating power level, iii) adding a controllable non-linear element, such as a diode or varactor, at the input of the RFPA, based on the average operating power.

  • Publication number: 20210274371
    Abstract: Methods and apparatus for selecting a beam mode and/or beam for communicating with one or more devices are described. The beam mode selection maybe and sometimes is between a broad beam mode of operation and a narrow beam mode of operation with respect to a particular device. Communication with one or more device may happen at a given time with the preferred beam mode and/or choice for an individual device sometimes being replaced with a beam mode and/or beam choice which is preferable from an overall system perspective, e.g., because it allows data transmission and/QoS requirements to multiple devices to be supported better than would be achieved if the preferred beam mode and/or beam selection made with respect to an individual device was used. The beam mode and/or beam selected for traffic data communication sometimes is different from the beam mode and/or beam used for communicating control channel information.

  • Patent number: 9935685
    Abstract: A network such as an in-vehicle powerline communication (PLC) network may allow PLC nodes to communicate over existing powerlines. Provided in the present disclosure are exemplary techniques for synchronizing network nodes (e.g., PLC nodes) with a network clock for the network so that data generated at each node may share a common time reference. For example, a synchronization (sync) signal may be generated by a master node and broadcast to other PLC nodes over a PLC channel, which may also carry data frames to and from other PLC nodes. The network clock may be autonomously generated by the master node or may be tied to an external clock.

  • Patent number: 9485695
    Abstract: A mobile communications device initiates a handoff from its current base station (BS) sector network attachment point to a new BS sector. The mobile sends a handoff request over its current wireless link to the current BS sector, which forwards the request to the new BS sector. The new BS sector processes the request assigning dedicated resources. Information identifying the allocated resources is conveyed from the new BS sector via the current BS sector to the mobile. The mobile determines the time of the allocated dedicated segments based upon a received beacon signal from the new BS sector with known timing relationships to dedicated segments. The mobile breaks the original wireless link just prior to the time of the first assigned dedicated segment. The mobile communicates information on the assigned dedicated segments to perform registration operations establishing a new wireless link.

  • Patent number: 9428127
    Abstract: A mobile computing device is operated to control a vehicle. A digital key for accessing a vehicle is stored for accessing the vehicle. Profile information is associated with the digital key for configuring operation and/or use of a vehicle. The profile information may include one or more outside parameters for implementing one or more pre-entry vehicle configurations. When one or more proximity conditions are detected as being satisfied as between the mobile computing device and the vehicle, a communication is sent to the vehicle in order to cause the vehicle to implement one or more pre-entry vehicle configurations. The communication can be based on the digital key and may specify the one or more outside parameters.

  • Patent number: 9358940
    Abstract: In response to detecting the entry condition, a determination is made as to when multiple mobile computing devices are present within the vehicle. An occupancy zone is determined for each multiple mobile computing device that is determined as being present within the vehicle. Profile information is determined for each mobile computing device. At least one of an operational or usage facet of the vehicle can be configured at each occupancy zone in which one of the mobile computing devices is determined to be present. The operational or usage facet of the vehicle at a location of each occupancy zone can be based at least in part on the profile information determined from the mobile computing device that is deemed to be present at that occupancy zone.
