  • Patent number: 11122259
    Abstract: A test voltage sample and hold circuitry is disclosed in a readout circuitry of an image sensor. This circuitry samples a voltage at demand value based on a ramp voltage shared by the ADC comparators of the readout circuitry. The value of the sampled voltage is controlled by a control circuitry which is able to predict and calculate at what time a ramp generator may carry the demand voltage value. The sampled voltage is held by a hold capacitor during readout of one row and is accessed during the next row by the control circuitry as test data to drive a device under test (DUT) which may be any portion of the image sensor to be tested. Measured data out of the DUT is compared with expected data. Based on the result of the comparison, a signal indicates the pass or fail of the self-test concludes a self-test of the DUT.

  • Publication number: 20210274441
    Abstract: A method, a device, and a non-transitory storage medium provide a false grant detection service. An end device may receive downlink control information when in a discontinuous reception active state. The downlink control information may include a new downlink transmission grant or a new uplink transmission grant. When downlink data pertaining to the new downlink transmission grant is unsuccessfully decoded, the end device may identify the new downlink transmission grant as a potential false grant and invoke a verification procedure. Depending on the result of the verification procedure, the end device may or may not start a discontinuous reception inactivity timer depending on whether the potential false grant is deemed a false grant or a valid grant. Similarly, the end device may invoke a verification procedure for a new uplink transmission grant. The detection of false grants may minimize the waste of power for the end device.

  • Publication number: 20210258835
    Abstract: Systems and methods described herein bring a 5G standalone-capable end device back into 5G service to leverage the 5G network's data capacity as soon as a VoLTE call is over. A network device receives a fallback connection, for a 5G New Radio (NR) standalone-capable end device, from a second network to the first network to support a voice call on the end device, wherein the fallback connection supports a voice-over-LTE call. The network device detects an end of the VoLTE call and initiates, in response to the detecting, a handover of the end device back to the second network, wherein the initiating occurs while the end device is in a radio resource control (RRC) connected mode.
