Abstract: Apparatus and methods are provided for thermal throttling for UE configured with multi-panel transceiving on FR2. In one novel aspect, the UE prioritizes throttling actions based on signal qualities of each transceiving panel. In one embodiment, the switching to the target panel from the active panel is selected as the highest priority throttling action when the signal quality of the target panel is similar to the active panel. In another embodiment, the UE further determines if the quality of the target panel is sufficient to support mmW transceiving before switching to the target panel. In one embodiment, the UE reduces one or more antennae of an active panel when the signal quality difference between the active panel and the target panel is bigger than a predefined gap threshold.

Abstract: A light emitter that operates through a display may cause display artifacts, even when the light emitter operates using non-visible wavelengths. Display artifacts caused by a light emitter that operates through a display may be referred to as emitter artifacts. To mitigate emitter artifacts, operating conditions for a display frame may be used to determine an optimal firing time for the light emitter during that display frame. The operating conditions used to determine the optimal firing time may include emitter operating conditions, display content statistics, display brightness, temperature, and refresh rate. Operating conditions from one or more previous frames may be stored in a frame buffer and may be used to help determine the optimal firing time for the light emitter during a display frame. Pixel values for the display may be modified to mitigate emitter artifacts.
