First Claim
1. A user equipment (UE) comprising:
- a transceiver to communicate through a wireless communication system;
a thermal finite-state-automaton comprising logic, at least a portion of which includes circuitry, the thermal finite-state-automaton comprising a plurality of system states and transitions between the plurality of system states, one or more of the plurality of system states based on a combination of network parameters for communicating through the wireless communication system and UE processing parameters, the plurality of system states comprising;
a default state 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 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, the peak performance configuration level to exceed the sustainable performance configuration level;
a recovery state 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, the reduced performance configuration level being less than the sustainable performance configuration level; and

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.
