  • Publication number: 20200053801
    Abstract: Techniques are described herein for collision handling in uplink transmissions. A user equipment (UE) may have more information to transmit during an uplink transmission than the allocated resources can handle. The UE may identify that an uplink transmission includes a plurality of different channels. The UE may exclude service types or scale the transmit power of service types based on performing a prioritization of the different channels in the uplink transmission. In some cases, the UE may prioritize ultra-reliable low-latency communications (URLLC) service types over enhanced mobile broadband (eMBB) service types. In some cases, the content of the URLLC service types and the content of the eMBB service types may be considered when prioritizing. The UE may be capable of configuring different sets of priority rules based on reliability thresholds and latency thresholds associated with the service types.

  • Publication number: 20200019749
    Abstract: Optical sensing is provided with a large sensing area in a thin package. For example, embodiments can operate in context of an under-display optical fingerprint sensor integrated into an electronic device, such as a smartphone. Responsive to reflected probe light passing through a display module, a reflective structure is configured to redirect the reflected probe light onto a refractive structure, and the refractive structure is configured to converge the reflected probe light into an input aperture of an optical sensor for detection. Some embodiments operate in context of an enhancement panel having micro-prism structures that tend to blur the reflected probe light. In such context, embodiments are configured for off-axis detection to prefer light passing through only certain micro-prism faces, thereby mitigating blurring.
