  • Publication number: 20240107414
    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for switching a secondary cell to a primary cell. A user equipment (UE) monitors a first radio condition of the UE for beams of a primary cell and a second radio condition for beams of one or more secondary cells configured for the UE in carrier aggregation. The UE transmits a request to configure a candidate beam of at least one candidate secondary cell as a new primary cell in response to the first radio condition not satisfying a first threshold and the second radio condition for the at least one candidate secondary cell satisfying a second threshold. A base station determines to reconfigure at least one secondary cell as the new primary cell. The base station and the UE perform a handover of the UE to the new primary cell.

  • Publication number: 20240105750
    Abstract: A CMOS image sensor includes PDAF pixels distributed in an array of image pixels in plan view. Each PDAF pixel includes m×m binned photodiodes, a PDAF color filter overlying the binned photodiodes and laterally surrounded by a first isolation structure, and a PDAF micro-lens overlying the PDAF color filter. A first horizontal distance between a center of the PDAF color filter and a center of the binned photodiodes varies depending on a location of the PDAF pixel in plan view in the CMOS image sensor. Additionally, the first isolation structure includes a first low-n dielectric grid, a second low-n dielectric grid underlying the first low-n dielectric grid, and a metal grid enclosed by the second low-n dielectric grid. The second low-n dielectric grid includes a filler dielectric material different from a second low-n dielectric grid material. Thus, quantum efficiency and uniformity of the CMOS image sensor are improved.

  • Patent number: 11941298
    Abstract: A host system initiates an abort of a command that has been placed into a submission queue (SQ) of the host system. The host system identifies at least one of a first outcome and a second outcome. When the first outcome indicates that the command is not completed and the second outcome indicates that the SQ entry has been fetched from the SQ, the host system sends an abort request to a storage device, and issues a cleanup request to direct the host controller to reclaim host hardware resources allocated to the command. The host system adds a completion queue (CQ) entry to a CQ and sets an overall command status (OCS) value of the CQ entry based on at least one of the first outcome and the second outcome.

  • Patent number: 11936418
    Abstract: A radar signal processing system with a self-interference cancelling function includes an analog front end (AFE) processor, an analog to digital converter (ADC), an adaptive interference canceller (AIC), and a digital to analog converter (DAC). The AFE processor receives an original input signal and generates an analog input signal. The ADC converts the analog input signal to a digital input signal. The AIC generates a digital interference signal digital interference signal by performing an adaptive interference cancellation process according to the digital input signal. The DAC converts the digital interference signal to an analog interference signal. Finally, the analog interference signal is fed back to the AFE and cancelled from the original input signal in the AFE processor while performing the front end process, reducing the interference of the static interference from the leaking of a close-by transmitter during the front end process.
