Publication number: 20240147376Abstract: 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.Type: ApplicationFiled: September 22, 2023Publication date: May 2, 2024Inventors: Chih-Chieh Lai, Feng-Wen Weng, Yu-Hung Huang, Chi-Hsiang Lin
