Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may attempt to establish a data session with a base station. The UE may transmit one or more session request messages including one or more route selection descriptors (RSDs) to the base station, and the UE may determine a successful RSD that may be compatible with the network based on a session accept message received from the base station. The UE may store the successful RSD at a location in memory for use in future session establishment procedures. For example, the UE may go out of service, and may re-acquire service with the same network. In such cases, the UE may transmit a session request message including the previously-accepted RSD to re-establish a data session with the base station.

Abstract: The present disclosure relates to methods and apparatus for display processing. For example, disclosed techniques facilitate regional processing of images for under-display device displays. Aspects of the present disclosure can identify a subsection of a set of frame layers, the identified subsection corresponding to a lower pixel density region, relative to at least one other region, of a display. Aspects of the present disclosure can also blend first pixel data for each frame layer corresponding to the identified subsection to generate second pixel data. Further, aspects of the present disclosure can populate a buffer layer based on the second pixel data. Additionally, aspects of the present disclosure can blend pixel data from the set of frame layers and the buffer layers to generate a blended image. Aspects of the present disclosure can also transmit the blended image for presentment via the display.

Abstract: Aspects presented herein relate to methods and devices for display processing including an apparatus, e.g., a DPU. The apparatus may configure at least one mask layer including a set of mask units associated with a set of physical sub-pixel values, the at least one mask layer being configured based on a target display configuration. The apparatus may also store the at least one mask layer to a device storage of a device. Further, the apparatus may retrieve the at least one mask layer from the device storage during a run-time period. The apparatus may also compare the target display configuration to a current display configuration of a display panel. The apparatus may also apply or refrain from applying the at least one mask layer to the display panel during the run-time period based on the comparison of the target display configuration to the current display configuration.

Abstract: Aspects presented herein relate to methods and devices for display processing including an apparatus, e.g., a DPU. The apparatus may receive each of a plurality of frames in a scene. The apparatus may also convert a data format for each of the plurality of frames to one or more DSC bit streams for each of the plurality of frames. Further, the apparatus may store the one or more DSC bit streams for each of the plurality of frames in a first memory or a first cache. The apparatus may also read the one or more DSC bit streams for each of the plurality of frames from the first memory or the first cache. The apparatus may also transmit, to a display panel, the one or more DSC bit streams for each of the plurality of frames.

Abstract: Methods and apparatus for graphics processing, such as producing a smooth transition between images of different dynamic ranges (e.g., Standard Dynamic Range (SDR) images and High Dynamic Range (HDR) images). An example method generally includes using a high frame rate during a transition period to allow properties of images to incrementally vary. The properties may include brightness (i.e., luminance), color gamut, tone mapping, among others. For example, during the transition period, a subset of HDR images are displayed at a second frame rate (e.g., 120 Hz) higher than a frame rate based on the HDR images (e.g., 30 Hz). Simultaneously, a brightness level (as well as other aspects) of the display panel is adjusted incrementally from an SDR brightness level to an HDR brightness level during the transition time period over the subset of the HDR images.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive first configuration information indicating a transmission time interval (TTI) bundling resource. The UE may receive second configuration information indicating semi-persistent scheduling (SPS) resources. The UE may detect, during a communication session, an SPS trigger for using the SPS resources in a subframe that is misaligned with a periodicity associated with the TTI bundling resource. The UE may determine whether the SPS trigger is valid based at least in part on a number of TTI bundling grants subsequent to the detection of the SPS trigger that are misaligned with the subframe associated with the SPS trigger. Numerous other aspects are provided.

Abstract: A user equipment (UE) may be equipped with multiple subscriber identity modules (SIMS) capable of supporting emergency calls. When an emergency call is detected, the UE may send emergency call requests to a network through the multiple SIMS. The UE may handle the emergency call through whichever SIM that receives the earliest successful response from the network. By utilizing multiple SIMS to establish the emergency call, both reliability and session response time may be enhanced.

Abstract: Certain aspects of the present disclosure provide methods and apparatus for generating, in a display panel, a virtual mask layer around a cutout region for a front camera. The front camera may be positioned under the display panel and receive light through the cutout region. The mask layer may hide defects of the cutout region that does not have functional pixels. The disclosed techniques may improve aesthetic appearance of displays having punch-hole cameras with reduced hole sizes and increased production quality conformance rate.
