Abstract

A thermal finite-state-automaton includes system states and transitions between the system states. The system states may be based on a combination of network parameters for communicating through the wireless communication system and UE processing parameters. A default state is for operation of the UE at a sustainable performance configuration level for the network parameters and the UE processing parameters to maintain a UE temperature below a first temperature threshold. A high state is for operation of the UE during up to a maximum time duration at a peak performance configuration level for the network parameters and the UE processing parameters. A recovery state is for operation of the UE during at least a minimum time duration at a reduced performance configuration level for the network parameters and the UE processing parameters. An emergency shutdown state is triggerable by the UE temperature exceeding a second temperature threshold.
