Abstract: An electronic device having multiple antenna groups for data communication may determine a temperature of a first antenna group and determine a power gain of a second antenna group. The electronic device may communicate using the second antenna group in response to determining that the temperature of the first antenna group exceeds a temperature threshold and the power gain of the second antenna group exceeds a gain threshold. In some embodiments, the electronic device may receive communication link preferences, determine an antenna group that is disposed outside of thermal hotspots of the electronic device, and determine a beam that enables the communication link preferences via the antenna group. The electronic device may then transmit or receive data via the antenna group by forming the beam.

Abstract: Some aspects relate to apparatuses and methods for selecting a receiving beam based on hybrid channel based beamforming and codebook based beamforming. A user equipment (UE) can determine, based on a first measurement related to signal to noise ratio (SNR) and predetermined threshold values, whether the UE is in a low SNR state. If the UE is in a low SRN state, the UE can derive an estimated channel covariance matrix RCH for channels at a set of antenna elements of the UE based on channel based bearmforming (CHBF). Afterwards, a set of test bears {0, . . . Ntest?1} is selected based on the channel covariance matrix RCH, and a set of codebook measurement beams is further selected based on the set of test beams. A receiving beam is selected based on a set of measurements performed on the set of codebook measurement beams at the measurement opportunity for codebook based beamforming (CBBF).

During regular device operation, conditions internal/external to the device is detected and the corresponding thermal throttling mode (from the LUT) is applied. In certain implementations, optimization algorithms are used in place of the LUT.

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.
