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: Communication device may include a transmitter and a receiver respectively coupled to one or more antennas to communicate (e.g., transmit or receive signals) with a base station. The communication device may receive an operating characteristic of a cellular modem within the communication device operating in a first cellular configuration and determine if the operating characteristic are greater than a threshold. The operating characteristic may include power and/or temperature. The threshold may include a power budget and/or a temperature threshold. If the operating characteristic is greater than the threshold, then the communication device may determine a control effort value based on the operating characteristic and the threshold. The communication device may map the control effort value to a second cellular configuration, which may correspond to reduced operating characteristics in comparison to the first cellular configuration. The communication device may then cause the cellular modem to operate in the second cellular configuration.
