Abstract: Various aspects of the present disclosure include methods, components and wireless devices configured to determine appropriate generalized system-wide thermal management policies and settings in wireless devices depending upon whether communication activities are driving or otherwise causing thermal conditions. In various aspects, a processor may determine workload characteristics and select and apply an appropriate thermal management policy/solution (or thermal configuration, settings etc.) based on the determine workload characteristics. The processor may determine workload characteristics based upon data from two or more temperature sensors within the wireless device. The processor may select a generalized system-wide thermal management policy suitable for operating when communication activities (e.g., 5G communication activities) are generating so much heat that CPU-centric thermal management policies are in appropriate.

Abstract: Various embodiments of systems and methods are disclosed for determining a thermal power envelope. One method comprises determining a set of component and operating point combinations for a plurality of components in a portable computing device. Each component and operating point combination in the set defines an available operating point for each of the plurality of components. The portable computing device is iteratively set to each of the component and operating point combinations in the set. At each of the component and operating point combinations, power consumption data and skin temperature data is collected from a plurality of temperature sensors. An enhanced thermal power envelope is generated comprising the power consumption data and the skin temperature data for each of the component and operating point combinations.

Abstract: Systems, methods, and computer programs are disclosed for providing optimal power/performance thermal mitigation in a portable computing device having a plurality of processing cores. An exemplary method comprises storing a power sweep table defining a power consumption value for each of a plurality of core frequency and core count combinations for an integrated circuit having a plurality of processing cores. A search table is generated by filtering the power sweep table based on one or more configuration parameters associated with the integrated circuit. A target power level is selected to sustain a thermal power envelope for the integrated circuit. The search table is traversed to find one of the plurality of core frequency and core count combinations having a corresponding power consumption value that matches the target power level.

Abstract: Various embodiments of methods and systems for intelligent thermal power management implemented in a portable computing device (“PCD”) are disclosed. To reduce or increase power consumption in the PCD, embodiments adjust one or more performance settings for active components in a given use case, the settings of which contribute to power consumption associated with an aggregate power consumption. The selection of active processing components for performance setting adjustment is a function of the change in user experience versus the change in power consumption that will likely result from the setting adjustment.

Abstract: A Sustained Thermal Power Envelope may be generated by monitoring a circuitry-level temperature in a portable computing device, monitoring a skin temperature of the portable computing device, monitoring an ambient temperature, operating the portable computing device during multiple time periods during which a circuitry-level temperature remains substantially constant, determining an average skin temperature during each time period, adjusting the skin temperature data by subtracting the ambient temperature, and generating data pairs of adjusted skin temperature and the power consumed during the time period.
